Alaska Cruise Weather: May-July Overview

Erica Silverstein

• February 8, 2021

Alaska is known for its unpredictable and often erratic weather, so many travelers hesitate over which month to book their sailing. 

While winter months carry a certain magical allure, most opt for spring or summer trips due to vibrant landscapes, extended daylight hours, and milder temperatures. 

It’s also during this period that travelers can indulge in fishing and wildlife-viewing opportunities.

Check out our guide to Alaska cruise weather for May, June, and July. In addition to monthly stats, discover the other seasonal variations that can help you pick the perfect time to cruise. 

Alaska Cruise Weather: May

In May, Alaska cruise temperatures average between 40 and 55 degrees Fahrenheit. 

May tends to be slightly rainier than June and July, with a slight chance of snow earlier in the month. 

Ketchikan, a popular stop for cruise ships, is one of the rainiest places in North America. It averages about 9.5 inches of rain in May. So if you’re cruise includes a visit to Ketchikan, it wouldn’t hurt to pack your rain gear. 

Ketchikan averages 16 hours of daylight in May; you’ll get even longer days as you travel north to Anchorage and still more if you take a cruise tour up to Fairbanks. 

However, daylight hours in May are a few hours shorter than what you’ll experience if you travel around the spring equinox in late June. 

Expect to see plenty of snow-capped peaks in May. If you travel up into the hills or mountains on a shore excursion, it’s common to find snow still on the ground. As such, you’ll want to pack waterproof hiking boots and warm, waterproof layers (don’t forget gloves and hats) to handle any wet or chilly spring weather. 

Mosquitos aren’t a problem in May. They’re in the summer, so you don’t have to worry about pesky insects while enjoying your vacation. 

If you’re planning a cruise tour to Denali National Park and Preserve, it’s worth noting that the bus service doesn’t begin until late May. The road through the park is only partially open until early June. 

For nature lovers, you’ll be glad to know that May marks the beginning of the salmon-fishing, whale-watching, and wildlife-viewing seasons. 

Although you can spot whales and go fishing any time during the Alaska cruise season, late May and early June are considered the best for seeing mammals because this is when moms and babies search for food. 

If budget is as big a concern as Alaska cruise weather, May is one of the cheapest months to sail due to shoulder-season discounts.

Alaska Cruise Weather: June

If you’re planning an Alaska cruise in June, temperatures average a low of 45 and a high of 62. 

June is tied with July as the least rainy month, with Ketchikan receiving an average rainfall of less than 7.5 inches.

Alaska cruise weather in late June is some of the best, with 18 hours of daylight and plenty of sun. If you’re lucky, it might even get warm! 

With drier ground in June than in May, Alaska cruisers can start to hike in earnest. 

Whether on your own or with a guide, be sure to pack appropriate gear, such as backpacks with bear bells, water bottles, snacks, and—most importantly—bug spray. The mosquitos start being a nuisance in June. 

For other shore excursions, layering is your best bet. You might need a fleece jacket in the morning but find yourself stripping down to a T-shirt by early afternoon. A packable rain jacket is always good to have on hand since you never know when you’ll get caught in a summer squall. 

The warmer Alaska weather makes June (and July) the best times to see calving glaciers during scenic cruise days. 

June is also one of the best months for whale-watching; late June and early July are the best times for bear-spotting excursions. 

Because of the fine Alaska weather in late June, it’s an excellent time to plan a cruise tour to Denali. The roads are open, days long and dry, and there’s an increased chance of seeing active wildlife.

Cruise fares in June will be higher than in May but better than in the prime summer months.

Alaska Cruise Weather: July

July offers the best Alaska cruise summer weather. It has the least rain (less than 7.5 inches in Ketchikan), long days (17 to 18 hours of daylight), and a warm climate. Temperatures average a low of 48 and a high of 65.

Pack your sunglasses, sunscreen, and your bathing suit for a top-deck dip after your shore tour. Despite the positive forecast, you’ll still want to pack light layers and rain gear that you can don for glacier viewing or visits, forested hikes, or the always-possible rain shower.

Fishing enthusiasts will do their best cruising in July since most types of salmon are running during this month. As with June, it’s an ideal month for wildlife viewing, whether you seek out bears, moose, or Humpback whales.

The glaciers along your route will be cracking like mad, so make sure your July cruise swings by Hubbard Glacier, Glacier Bay, or other scenic cruising destinations. 

You’ll have the full range of cruise tour destinations open to you if you travel in July. But be warned: Cruise fares average the highest this month because the Alaska cruise weather in July is so nice, and more families are traveling because school is out for the summer.

Frequently Asked Questions

What is the best time to cruise alaska .

The answer entirely depends on your travel goals.  In general, the best time to cruise Alaska is from July to September due to milder weather and longer daylight hours. During these months, tour destinations and attractions are open and fully operational, so you can enjoy the full Alaskan experience. 

However, May and June also come with their own perks. For one, they’re excellent months for wildlife viewing. The landscape becomes alive with hundreds of migratory birds, and you’ll have a good chance to spot bears, whales, and other wildlife. 

Furthermore, May and June bring competitive pricing for cruises compared to the peak season in July. This can be advantageous for budget-conscious travelers. 

What is the best time of year to see the northern lights in Alaska cruise?

Northern lights in Alaska usually appear during the aurora seasons, which typically fall in April, August, and September. It’s less likely to occur between May and July due to the extended daylight hours and the midnight sun

Can I still see glaciers during an Alaska cruise from May to July?

Yes! In fact, most glacier excursions are best done in summer and early fall months, which coincidentally falls between May and July and extends till September. Glacial activities, such as calving, are more pronounced during these periods due to warmer temperatures.

Alaska Cruise Weather by Month

The Alaska cruise season generally runs from May to September, with occasional cruises in April and October.

The below chart shows the Alaska cruise temperatures you can expect on the inside passage, along with rainfall and hours of daylight:

Alaska Cruise Weather in May

• Highs : 55°F
• Lows : 40°F
• Average Rainfall : 3.48 inches
• Hours of Daylight : 16.5 hours of daylight

Many cruise ships begin their summer deployments to Alaska in May before peak season begins in June.

The Alaska cruise weather in June is fairly cool, but it has the least amount of rainfall during the Alaska cruise season. You can expect Alaska cruise temperatures in May to have lows of around 40 and highs of around 55 degrees Fahrenheit.

May is one of the best times to visit Alaska for dry weather, fewer crowds, and lots of wildlife.

During May, you’ll find several whale species along Alaska’s inside passage. By this time of the year, most of the whales will have completed their migration from the warm waters of Mexico to Alaska, where they will spend the summer.

Spring is also the time to spot newborn wildlife.

You can expect to see lots of snow-capped mountains, and there are fewer insects and mosquitos.

Alaska Cruise Weather in June

• Highs : 60°F
• Lows : 45°F
• Average Rainfall : 3.36 inches
• Hours of Daylight : 18.1 hours of daylight

Early June is when the Alaska cruise season kicks into high gear. The warming weather allows cruise ships to travel through the Arctic waters providing unique opportunities for passengers.

The Alaska cruise temperature is warmer in June, with lows of 45 and highs in the low 60 degrees Fahrenheit. Make sure to pack insect repellant when you visit Alaska in June, as mosquitos and other insects can become a nuisance.

The warm weather makes it one of the best times to witness the calving of glaciers.

You can expect 18-20 hours of daylight in June, providing lots of time to enjoy the Alaskan wilderness and abundant wildlife.

June is one of the best months for wildlife sightings, with caribou, black bears, mountain goats, moose calves, and even polar bears out and about.

Alaska Cruise Weather in July

• Highs : 65°F
• Lows : 50°F
• Average Rainfall : 4.14 inches
• Hours of Daylight : 17.3 hours of daylight

July is the peak season for Alaska cruises and provides the best Alaska cruise weather and wildlife opportunities. This month has some of the warmest weather, longest daylight hours, and the largest number of tourists.

Temperatures in July average from the high 40s to 65 degrees Fahrenheit.

The warm weather and long hours of sunlight mean you’ll want to pack sunglasses and sunscreen. You should still wear layers when visiting the port, but if you’re planning active shore excursions like hikes or glacier walks, you’ll want to stick with lightweight clothing.

July is an ideal month to visit for salmon fishing, cultural festivals, bear viewing, and small-town exploring. With the popularity of July cruising, cruise prices are at their highest.

Despite having the best weather, Alaska’s weather in July is very unpredictable. You’ll want to pack for all kinds of weather and wear a lightweight rain jacket.

Alaska Cruise Weather in August

• Average Rainfall : 5.37 inches
• Hours of Daylight : 15.2 hours of daylight

August is when the Alaska cruise season begins to wind down. During this month, you can expect the weather begins to cool, higher rainfall, and gorgeous fall landscapes.

You may be able to find some deals towards mid-August, but expect full fares for the most part.

The chance of rain during this month is over 50%, so you’ll want to pack plenty of waterproof gear – including waterproof shoes and wool socks.

Alaska Cruise Weather in September

• Average Rainfall : 7.54 inches
• Hours of Daylight : 12.4 hours of daylight

As school returns to session, cruise prices dip and provide travelers with last-minute bargains to take an Alaskan cruise.

The temperatures in September are slightly cooler, with highs of 55 and lows around 40 degrees fair height. September is also the rainiest month of the cruise season. So be prepared to pack lots of rain gear.

September also sees fewer crowds than in the summer. However, the shoulder season has become more prevalent in recent years, making great deals harder to find. Knowing when to book your cruise can help you save money on your trip.

Due to the shorter daylight hours, September provides the best opportunity to see the Aurora Borealis from an Alaskan cruise.

The Best Time to Cruise Alaska: A Month-by-Month Guide

Sharing is caring!

Choosing the best time of year for an Alaskan cruise can be challenging. From month to month, the weather, wildlife, and your chances of viewing the mesmerizing Northern Lights vary greatly.

Since I grew up in Alaska, I’m a fan of just about everything in the Land of the Midnight Sun. I also know that your experience can vary widely depending on the month you choose to visit Alaska.

Which raises the question…

When is the Best Time of Year to Cruise to Alaska?

The abbreviated Alaskan cruising season goes from May to September. Although you’ll find the highest number of travelers visiting Alaska during the peak cruising (and fishing) months of July and August, the ideal time for your Alaskan cruise depends most on your personal priorities.

In this post, I share a month-by-month guide about the best time of year for an Alaskan cruise. I’ve included tips on the weather, wildlife, daylight, and the general experience you’ll have each month of the Alaska cruise season to determine when to set sail for the 49th state.

Alaska Cruise Season

The cruising season to Alaska is shorter out of necessity. Weather, ocean conditions, and limited sunlight make winter cruising to Alaska impossible.

For major cruise lines, the Alaska cruise season runs between May and late September, including Viking and Disney.

Many cruise lines also have limited early cruise ships departing for Alaska in April. Norwegian Cruise Lines has the first departures of the season in early April from Seattle.

Holland America Princess, and Royal Caribbean have Alaskan Inside Passage cruises departing from Vancouver at the end of April. Carnival has 14-day Alaskan cruises departing from Seattle and Long Beach in late April.

Alaskan Cruise Month-By-Month Guide

What to Expect on an Alaskan Cruise in April

Spring in Alaska is a unique experience. The benefits of cruising in April include less expensive pricing, fewer tourists, and less crowded ports. Here is a breakdown of other important considerations for an April Alaskan cruise.

Locals typically call the months of April and May “break-up” because the snow and ice begin to break apart and melt after the long winter. What does this mean for tourists? Snow and mud! In April, mountains will still be snowy, and high temperatures will max out in the upper 40s for most cruise ports.

April marks the beginning of the dry season for Southeast Alaska. However, it’s important to remember that this area is part of the world’s largest temperate rainforest.

The average rainfall in Juneau during the month of April is 2.77 inches. Although the rain isn’t convenient, it is the reason for the lush vegetation you enjoy.

Be sure to pack high-quality rain gear for excursions along with warm, layered clothing and a hat and gloves. Many early spring cruisers also pack a winter coat.

Because of its latitude, Alaska experiences extremes in daylight in the summer and darkness in the winter.

On Winter Solstice (December 21 or 22), the state breaks out of its winter hibernation and begins gaining a few minutes of sunlight each day. By the time Summer Solstice occurs (June 20,21, or 22), travelers to Juneau, Alaska, a common port, will experience a day with 19 hours of sunlight.

In April, towns along the Inside Passage will have just over 15 and a half hours of sunlight and will be gaining daylight every day.

Since the skies do still get dark during this month, there is a slight chance that you’ll be able to view the Northern Lights on an Alaskan cruise in April. Peak viewing of the Aurora Borealis happens between November and March, but on a clear night with lots of solar activity, you have a shot at this once-in-a-lifetime viewing experience.

When it comes to Alaskan cruises, balcony cabins come at a premium. You can save money by opting for an inside or an oceanview cabin. However, the views and ability to go sightseeing from your room on ocean days make the higher price worth it.

If you purchase a balcony cabin, you can take advantage of the long days in the Land of the Midnight Sun. As your ship reaches the Inside Passage, the early morning views outside of your room are breathtaking.

There are plenty of animals to see while cruising to Alaska. Arguably, the biggest draw is the marine animals, with opportunities to see pods of humpback whales, gray whales, orcas, sea lions, sea otters, and more.

There are also amazing birds, including bald eagles and land animals like mountain goats, Dall sheep, and brown and black bears.

Although gray whales are more elusive than their humpback cousins, April is your best chance to spot them as they migrate from their winter breeding grounds in Baja, Mexico, to feed in the waters inside the Interior Passage of Alaska.

Orca whales (which are actually members of the dolphin family) are a fairly common site on an Alaskan cruise. “Resident” orcas (who stay near shore and feed on fish) are easy to spot and fun to watch from the cruise ship or on a whale-watching excursion.

General Experience:

Choosing to cruise in the early spring of Alaska will impact your experience. Less travelers might sound appealing, but many port towns aren’t fully “tourist operational” until late June when summer workers start to arrive.

An April sail date is one way to save money on your Alaskan cruise. Just expect cooler weather, fewer wildlife viewing opportunities, and less active ports with some shops that are still shuttered.

What to Expect on an Alaskan Cruise in May

Cruising to Alaska in May is still considered early in the season. As the month progresses, temperatures rise slightly, and daylight hours increase.

While prices in the early season are generally less expensive, your experience during a May cruise will look different from during the high season in July and August. Here is what you’ll find in Alaska in May.

Alaska will still be emerging from winter during May. The high temperature in May in the capital city of Juneau, averages in the mid-50s, with lows in the 40s.

In most Alaska ports, rainfall occurs about 15 days of the month. You’ve got about a 50/50 chance of getting rained or snowed on during excursions. You’ll be very happy if you purchase a quality raincoat and pack clothing you can add or remove in layers.

A hat, gloves, and a winter coat would be a good idea to pack for an Alaskan cruise, especially if you depart in April, May, or September.

Alaska is still gaining sunlight as the Summer Solstice approaches, so you’ll experience longer days during your May cruise.

At the beginning of the month, sunrise in Juneau begins at 5:00 a.m., and sunset is at 8:47, resulting in 15 hours and 47 minutes of daylight. As May closes, the days are even longer, with the sun rising in Juneau at 4:00 a.m. and setting at 9:49 p.m. (almost 18 hours of daylight!).

Another thing to keep in mind when deciding the best month for your Alaskan cruise is wildlife viewing opportunities.

Salmon usually begin their long journeys home to spawn in May, but they come in different waves or “runs.” You might have a chance to view bear feeding on salmon this early in the springtime, but your chances are better later in the summer.

There are exciting marine animals that you can see this early in the Alaskan springtime.

Alaska’s Stellar sea lions are an impressive sight for cruisers. Because they don’t migrate, you have a great chance of viewing these 1000+ pound, 10-foot-long animals on rocks near the shorelines as you cruise. Be sure to listen for their signature roar.

There is also potential for viewing orcas, gray whales, and walruses.

May is an excellent cruising month for birdwatchers as migratory songbirds start to arrive in Alaska and seabirds gather in their nesting spots or rookeries. Keep an eye out for my favorite, the ever-adorable puffins, Arctic terns, cormorants, and bald eagles.

May is a practical choice for Alaskan cruisers who are on a limited budget but want to have slightly warmer and drier weather and more chances to see wildlife. Your views will likely include snowy mountains, but they are gorgeous nonetheless.

Expect less activity and fewer shop openings in some smaller port towns in May since most summer workers are in college and won’t arrive until June.

What to Expect on an Alaskan Cruise in June

Things start hopping in Alaska in June. Summer workers (typically college students) begin to arrive for the peak tourist season, and shops and restaurants open for the summer.

As the temperature warms up, the snow on the ground in port towns melts, and more wildlife begins emerging from their winter dens.

Because school is often still in session for younger children in May and June, taking an Alaskan cruise in the early Spring/Summer is a good choice if you prefer fewer children on board.

In the Lower 48, temperatures in June start to heat up, not so much in Alaska.

While temperatures are warmer and the snow is typically gone at lower elevations, the highs in Juneau average in the low 60s, with lows in the upper 40s.

Temperature is relative, so don’t be shocked if you see an Alaskan sporting shorts and a tank top in June. The 60s can feel downright tropical after winter temperatures in the 20s and 30s.

Rainfall slows down a bit in June, with about 13 days of the month having some precipitation.

Packing-wise, you’ll still want to bring a raincoat, but you can probably leave your winter coat home if you are cruising in June.

It is remarkable to experience Alaska on or around the summer solstice. The amount of daylight increases as you travel northward, but even Juneau’s 19-hour solstice day, with the sun rising at 3:48 a.m. and setting at 10:09 p.m., is a fantastic experience.

If you are in port, you’ll get to see how Alaskans take advantage of the Midnight Sun with locals out biking, hiking, and fishing at all hours of the night.

You’ll also have more hours to look for wildlife from your room window or veranda.

If you have an exterior room and are sensitive to light while sleeping, a sleeping mask will help you rest during these long days.

Humpback whales are the most commonly seen whale in Alaska. They begin migrating from Hawaiian waters in the springtime to feed in the nutrient-rich Alaskan waters.

While it is possible to see humpbacks during the entire cruise season (April-October), your best bet for whale watching will be the months of June, July, and August. They are quite an awe-inspiring sight to see as they travel in pods, breech, and feed.

This is also the time of year when King Salmon runs both begin and end. If you are an angler, there is nothing like hooking and reeling in a King. With an average size of 24 to 36 inches and weighing 10-50 pounds, you’ll finally have a true fishing story worth telling.

If you cruise to Alaska in June, you can expect warmer and drier temperatures, fewer children onboard, increased wildlife sightings, and more cruise offerings.

June is a smart choice for cruisers who don’t want to travel during peak season but want more opportunities.

What to Expect on an Alaskan Cruise in July

Weather is a pretty big consideration when it comes to booking an Alaskan cruise. Temperatures can be quite chilly on deck and in ports of call. If you have a low tolerance for cold weather, cruising Alaska during the warmest months of July and August is a better choice.

July and August are considered peak seasons to cruise to Alaska for good reason. These are the months when all good things combine to create the optimal Alaskan experience.

That being said, the weather and wildlife in Alaska are notoriously unpredictable. You could book a cruise in July and never get above the 50s. You might take a float plane to see bears and, sadly, not see a single one.

My advice is to pack plenty of warm (and waterproof) layers , expect the unexpected, and find joy in whatever experience you get.

The weather in July only trends slightly warmer than June. The average July temperature in Juneau is 64 degrees, with an average low of 51 degrees.

The dry season ends, and precipitation starts to increase in July. Rain falls on average 14 days of the month. Just remember our earlier reminder that you are visiting the world’s largest temperate rainforest and enjoy the lush greenery.

After the Summer Solstice in June, Alaska begins losing daylight with each passing day. While the days are still longer than those in the Lower 48, they are getting slightly shorter throughout July.

In Juneau, the sun rises at 3:54 a.m. at the beginning of July. By the end of July, it starts rising at 4:45 a.m.

Sunsets move to earlier in the night as the month progresses. The sunset on July 1 in Juneau is at 10:07 p.m., and by the end of July, it is at 9:21 p.m.

Although it is getting darker earlier, solar activity is not at its peak in the summer, so your chances of viewing the Northern Lights in July are slim to none.

July is a spectacular month for viewing wildlife in Alaska. Not only are humpback whales, orcas, sea lions, eagles, and seabirds easier to see as they feast in the nutrient-rich summer waters, but the likelihood of seeing the indomitable Alaskan brown, black, and Kodiak bears increase as they focus on fattening up on migrating salmon.

Small-ship Alaska cruise lines like American Queen Voyages and Uncruise can go further into narrow passages and get closer to shoreline wildlife like Dall sheep and bears.

If bear viewing is high on your bucket list and you are traveling on a bigger cruise ship, look for a float plane excursion that will take you to where the bears feed.

July is filled with opportunities to see the stunning wildlife of Alaska while enjoying milder temperatures.

July also brings the highest number of tourists to Alaska. If you cruise to Alaska this month, you can enjoy more shop and restaurant options in port towns but expect things to be slightly more crowded.

What to Expect on an Alaskan Cruise in August

August is a delightful time to cruise to Alaska. You’ll enjoy wildlife viewing, warmer temperatures, and daylight returns to more typical hours. However, the dry season has ended, so rainfall will begin to increase as the month progresses. 

For cruise itineraries in Alaska, August high temperatures will be somewhere in the upper 50s and low 60s. We’ve reached the pinnacle of summer temperatures, and the rainier season has just begun.

Juneau gets about 17 days of rain in August, so a high-quality raincoat is essential.

With lows in the 50s, you don’t need to pack a winter coat and hat, but be sure to include warm, wicking layers to keep your temperature steady.

By the end of August, the sunrise and sunset times in Alaska are pretty close to “normal” times for most states in the USA. You might feel like you aren’t getting the true Alaskan “Midnight Sun” experience this month. 

In Juneau, on August 31, the sunrise is at 5:52 a.m., and the sunset is at 8:01 p.m.

The loss of daylight does mean you could see the Aurora Borealis while cruising to Alaska in late August. The best time to see the Northern Lights is between late August and April, typically peaking in March.

Unfortunately, seeing this supernal show of sun activity is not a given. Overcast skies are common in Alaska and block the Lights, and the solar activity that creates the phenomenon is unpredictable. You can increase your chance of seeing the Northern Lights by asking crew members if you can get placed on a list that will be notified when, as we say in Alaska, “the lights are out.”

In August, the wildlife can sense that winter is on its way, and activity picks up to prepare for the months of cold, snow, and darkness.

You might see bears that are continuing to fatten up before hibernation. Humpback whales have yet to begin their migration to warmer waters, so you will still be able to see them, especially in early August.

Seabirds will still be feasting on fish. You also might see fuzzy harbor seal pups and sea lion pups (born in June and July) warming themselves on rocks with their mothers. Add high-powered binoculars to your Alaska packing list to ensure that you get to see all of the wildlife possible.

General Experience :

You can’t go wrong with a cruise to Alaska in August. Not only is it your best shot for warmer weather, but you’re also sure to see a good amount of the wildlife Alaska is famous for.

Warmer weather in Alaska also has an unexpected bonus for cruisers in the form of glacial calving.

Glaciers are a natural wonder that no photographs can do justice. Until you have experienced the majesty of an ancient river of ice in an unparalleled blue, it is hard to imagine!

Every Alaskan cruise includes at least one glacier viewing stop. The warmer the weather, the better your chance to view a once-in-a-lifetime occurrence called “calving.” This is when a large chunk of the glacier separates in a giant icy landslide.

Not only is the cracking sound shocking, but the calving also produces a giant wave of water and captivating icebergs. July and August are prime time for viewing glacier calving on an Alaskan cruise.

What to Expect on an Alaskan Cruise in September

April, May, and September are considered shoulder seasons for cruising to Alaska. Shoulder season is the time between peak season and off-season when there are fewer cruisers and lower prices.

A September cruise has its benefits, including less crowding and cheaper prices. However, a cruise this time of year will also slightly decrease your chance of viewing wildlife and make for sleepier ports of call because most summer workers return home for college.

In Alaska, we measure the return to winter by how far up the stalk Fireweed flowers have bloomed. By September, the blooms are most certainly to the top as winter rapidly approaches.

High temperatures in September in Juneau hover around the upper 50s with lows in the mid-40s, though, so it is still an enjoyable time to visit.

Precipitation increases to 19 days of the month, so pack a raincoat with a hood (you’ll be grateful to have it!).

There is a chance you will see some snow, so a winter coat, gloves, and a hat are a smart addition to your packing list.

In September, the scale now tips towards later sunrises and earlier sunsets in Alaska. By the end of September, there are less than 12 hours of daylight in Juneau.

Cruising in September will give you the highest chance of viewing the Aurora Borealis on an Alaskan cruise. You won’t want to miss this indescribable sight, so watch for clear night skies and set an alarm to go on deck (or on your balcony) for potential middle-of-the-night Northern Lights shows.

Gray whales and Humpback whales begin their migration to warmer waters in October and November, so you still have a chance to see them in Alaskan waters in September.

Birds also haven’t started their migration, so you can spot both songbirds and seabirds as you cruise along the coast.

Silver salmon runs are possible in September, but not a guarantee.

September is also an excellent time to witness a towering Alaskan moose. By this time of year, bull moose have a full rack of antlers. With shoulder heights at 6 foot 9 inches and over 1,400 pounds, these massive animals are as dangerous as impressive, so you’ll want to view them from a distance.

Cruising to Alaska in September has many benefits of the peak season (milder weather and good wildlife viewing) with less expensive prices and fewer tourists.

Although the weather will likely include more rain, you have a better chance of viewing the Northern Lights, which might outweigh this drawback.

If your itinerary includes stops in Anchorage, Seward, or Whittier, you might experience rougher seas as you cross the Gulf of Alaska in September.

FAQs About Alaskan Cruises

What is the best time of year to see the northern lights on an alaska cruise.

The peak season to view the Northern Lights or Aurora Borealis is between late August and late April, which unfortunately doesn’t overlap much with the Alaskan cruise season. If the Northern Lights experience is high on your Alaska bucket list, consider a September cruise with more dark nighttime hours and increased solar activity.

How far in advance should you book an Alaskan cruise?

If you are hoping to travel during peak Alaskan cruise season (July and August), you should plan on booking your Alaskan cruise at least one year in advance. The farther in advance you can book your Alaskan cruise, the more options you will have for cruise dates, itineraries, and cabin amenities.

Are the seas rough on an Alaskan cruise?

When traveling from Vancouver in the Inside Passage of Southeast Alaska, the waters are mostly protected and provide smooth sailing. If ports include Anchorage, Seward, or Whittier, cruise ships must cross the Gulf of Alaska, which has notoriously rougher waters. This is especially true after Labor Day.

Cruise Tips for Alaska Weather: Month by Month

If you’re thinking about planning a summer cruise , Alaska may be the perfect destination for you. The Alaskan cruise season lasts from May to October, and the warmest months for travel are typically June, July, and August. Alaskan cruises may seem suited only for people who like extreme weather, but the truth is that the weather in Alaska varies widely based on the region.

Here’s what you can expect each month on your upcoming Alaska cruise along with what you really need to pack.  

Ready to start planning? Explore all Alaska cruises .

Alaska Cruise Weather in May

May brings warmer weather within the cities and towns of the Alaskan inside passage. While it can be freezing cold at times, the weather can also be pleasantly cool. The low temperatures typically range from the mid-thirties to the low forties Fahrenheit, but the highs can get up to the upper fifties.

This month also experiences near constant cloud cover with a good chance of rain on any given day. Travelers get at least fifteen hours of daylight and twilight in May, providing more time for whale watching and other outdoor activities. With low wind speeds, cold temperatures, and precipitation, travelers may want to pack plenty of knit sweaters, a jacket, warm pants, and waterproof boots or shoes.

Alaska Cruise Weather in June

Most of the month of June in Alaska is either cold or pleasantly cool with very cold temperatures being less frequent than in May. The lows can be as low as forty-three degrees Fahrenheit, and the highs can get up to the sixties on average.

Cloud cover and precipitation conditions from May persist throughout June and July, and wind speeds remain low as well. Layers are essential for this type of fluctuating weather, and travelers should be sure to pack waterproof jackets and shoes for rainy moments, cardigans or light sweaters, and other warm clothes like jeans, long skirts, and tights.

Alaska Cruise Weather in July

July is known as the hottest month in this section of Alaska with the hottest day of the year falling on July 9th. Temperatures range on average between fifty and sixty degrees with mostly cool afternoons and evenings and chilly mornings and mid-day hours.

The late nights and early mornings can be very cold, but these are also the hours when most people are asleep in their cabins. Travelers cruising to Alaska in July should be sure to pack plenty of layers along with some waterproof outerwear, but they should pack light, removable layers to adjust to the warmer temperatures of the afternoons.

Alaska Cruise Weather in August

August brings a gradual decrease in temperatures again, but it is still one of the hottest months of the year in this region. Temperatures during this month usually range from the mid-forties to the low sixties, and days are typically cool or chilly.

Like July, nights and early mornings can be very cold, so late nighters and early risers should be prepared to bundle up for icy temperatures. Plenty of layers are also essential in August, and travelers should be sure to pack waterproof jackets, shoes, and bags as August and September are among the rainiest months of the year.

Alaska Cruise Weather in September

September is one of the last months of the cruise season in Alaska and it is also one of the coldest, with temperatures staying in the low to high forties on average. As the month advances, the temperatures drop lower and lower, and the nights and early mornings can be bitterly cold.

The abundant cloud cover and frequent rain make the landscape all the more beautiful, but visitors should dress properly for a better overall experience. Travelers still get at least twelve hours of sunlight for excursions and deck activities, but they should pack thick pants, knit sweaters, and insulated shoes to combat the cold along with waterproof rain gear.

Alaska Cruise Weather in October

October in Alaska can see lows can be as low as 28° Fahrenheit, and the highs can reach up to 40° Fahrenheit. You can also expect more precipitation, which can result in some snowy weather.

Both September and October are ideal times to see the stunning Northern Lights, otherwise known as aurora borealis displays. The best times to look is between Midnight and 2am.

While Alaska might be colder than other summer vacation spots, it offers unique experiences that can’t be found anywhere else. These include sightings of wild orcas , sea lions, and humpback whales and riding one of the world’s longest ziplines.

You’ll also have a chance to visit the incredible Butchart Gardens, witness glaciers, pan for gold , hike through temperate rainforests, and much more. If you’re prepared for the weather and pack the right attire for your destination, nothing can get in the way of having a good time.

The Best Time for an Alaska Cruise: A Monthly Breakdown

• June 29, 2024
• Cruise Planning

If you’re planning an Alaska cruise, you might be wondering when the right time is to set sail. To help you decide, we’ve put together a month-by-month guide detailing the benefits of cruising in each month. Whether you’re interested in wildlife photography, enjoying pleasant temperatures, or finding the best deals and avoiding crowds, my guide will help you choose the perfect time for your Alaska cruise.

The Alaska cruise season is relatively short, running from late April to early October, with each month offering unique advantages. Summer is known for its warm temperatures and long days. Spring, on the other hand, has fewer tourists and more opportunities to see wildlife.

Why Choose an Alaska Cruise?

Choosing an Alaska cruise lets you experience some of the most stunning landscapes on Earth. From the awe-inspiring glaciers calving into the ocean to unique wildlife encounters in their natural habitats. Unlike Caribbean cruises that mostly traverse open waters, Alaska cruises offer close-up views of dramatic cliffs and lush forests. Additionally, the long days during the Alaskan summer allow more time for sightseeing and excursions.

Alaska shore excursions are unlike any other. Bear watching, glacier hikes, and kayaking through serene fjords are just a few of the excursions on offer. To really get the full Alaskan experience, consider adding pre- and post-cruise tours. These extensions give you extra time to explore Alaska’s rugged beauty beyond the coastline.

Beyond the stunning natural scenery, Alaska cruises offer passengers a deep dive into the local culture and history. Many itineraries include stops at native villages where you can learn about the indigenous peoples’ rich traditions, crafts, and ways of life.

Cruising Alaska in April

Some cruise ships will begin sailing at the end of April, but the majority start in May. Norwegian Cruise Line, however, does offer a good selection of cruises from mid- to late-April, particularly from cities like Seattle. Additionally, some smaller cruise lines might also offer departures later in the month. These can be excellent choices if you’re looking for lower prices and smaller crowds.

Weather-wise, April in Alaska is a transitional period. You can expect around 5 inches (13 cm) of snow early in the month, possibly mixed with some rain. Temperatures are on the colder side, ranging from 33 to 48°F (0.5 to 9°C). However, as the month progresses, the weather typically clears up.

As April progresses in Alaska, the natural world begins to awaken from its winter sleep. This is when wildlife, such as black bears, start to become active. If you’re cruising towards the end of April, you might be fortunate enough to see these bears as they come out of hibernation, especially in areas like Sitka. This time is also excellent for spotting bald eagles, humpback whales, sea otters, and orcas.

April is an excellent time to cruise through the Inside Passage, where you’ll be treated to clear waters and stunning coastal mountains—a great way to start the cruise season. For nature lovers, Ketchikan is another popular option. If the weather allows, you can explore rainforest hikes and go on wildlife tours, both of which are incredibly rewarding during this quieter time of the year.

Cruising Alaska in May

In May, Alaska’s weather becomes warmer and drier, making it a fantastic time for exploration and adventure. Temperatures during this time range from 38 to 55°F (3 to 12°C), with around 16.5 hours of daylight and minimal rain.

May is also a great month for wildlife enthusiasts. You might catch sight of black bears with their cubs, moose, caribou, and bald eagles, all drawn out by the salmon runs. It’s also possible to spot humpback whales and even orcas, making for excellent photography opportunities.

During this month, cruise lines including Royal Caribbean, Princess Cruises, and Disney start offering more cruises. It’s also the shoulder season, so you’re likely to see an increase in tourists and a rise in prices. However, the prices are still lower than during the peak season, making it a relatively affordable time to cruise. You can enjoy better deals on accommodations and excursions, as cruise lines aim to attract travelers before the busiest part of the year kicks in.

Glacier Bay becomes particularly breathtaking in May. As the cruise season ramps up, visitors have the opportunity to see glaciers calving and explore the serene fjords. Juneau is also a great place to visit during May. Here, you can go on whale watching tours, explore the city’s scenic hiking trails, or enjoy a ride on the Mount Roberts Tramway for panoramic views of the city and surrounding wilderness.

Cruising Alaska in June

June in Alaska sees a significant increase in both daylight and favorable weather, with average temperatures ranging from 46 to 62°F (8 to 17°C) and about 3.3 inches (8.4 cm) of rainfall. This pleasant weather, combined with nearly 18 hours of daylight, attracts more tourists, especially in the middle of the month. Early June offers a good opportunity for finding discounts and enjoying lower crowds before the peak season begins.

June is an excellent month for shore excursions, thanks to the favorable weather and extended daylight. Late June marks the beginning of summer, making it an ideal time to experience Alaska’s natural beauty. It’s also one of the best months for wildlife photography, with opportunities to capture images of humpback whales, moose, caribou, and bald eagles. However, you are unlikely to see many brown bears during this month.

One of the top destinations to visit in June is Denali National Park. The weather is ideal, with little rain and plenty of sunlight, making it perfect for exploring the park’s vast wilderness. Many cruise itineraries include stops at Denali, where you can enjoy guided tours, spot diverse wildlife, and hike through beautiful trails.

Skagway is another must-visit location in June. Visitors can take the White Pass and Yukon Route Railway, which offers stunning views of the surrounding landscape. Alternatively, guided hikes or bike rides let you explore Skagway’s natural beauty and historical charm.

Cruising Alaska in July

July in Alaska is the peak of summer, bringing long, dry days filled with plenty of sunshine. Temperatures range from 50 to 65°F (10 to 18°C), providing a comfortable climate for outdoor activities. However, July is also the peak tourist season, so expect large crowds and higher prices. 

During July, you can start to see brown bears in places such as Brooks Falls in Katmai National Park, hunting for salmon. Remember to bring sunscreen as the sun can be very strong during this month. While packing, include both warm layers for the cooler mornings and evenings, as well as lighter clothes for the warmer parts of the day.

There are plenty of activities to enjoy in Alaska during July. Independence Day events are held in cities like Anchorage, Juneau, and Fairbanks, featuring parades, fireworks, and local celebrations that give you a taste of Alaskan culture. 

In addition to Independence Day events, July is a perfect time to visit Alaska’s coastal towns and experience their unique charm. Visit Seward for its vibrant harbor, kayaking, fishing, and the Alaska SeaLife Center. Another must-see is Ketchikan, famous for its rich native culture and Creek Street boardwalk. Here, you can join guided wildlife tours to spot eagles, seals, and possibly even whales. 

Cruising Alaska in August

In August, temperatures in Alaska cool off a bit but remain relatively warm by Alaskan standards, ranging from 47 to 62°F (8 to 16°C). So, it’s still a comfortable time for outdoor activities and exploring Alaska’s scenery. The peak season for Alaska cruises wraps up in August. This month continues to attract a large number of visitors due to its pleasant weather and long days.

In August, cruising in Alaska tends to be busy as it is still part of the peak tourist season. The warm weather and extended daylight hours attract many visitors, resulting in larger crowds. However, the crowds are generally manageable, and the vibrant atmosphere adds to the overall experience. 

August is an excellent month for fishing, as the salmon runs are in full swing. It’s also the last month for brown bear spotting as they prepare for the winter. Berry picking is another popular activity in August before they disappear in September. 

Since August brings more rain, having jackets and waterproof clothing is recommended. Cruisers will find this month perfect for visiting scenic areas like Glacier Bay and going on wildlife tours to spot bears. For more unique experiences, consider taking a fjord cruise or a guided nature walk.

Cruising Alaska in September

September marks the start of Alaska’s second shoulder season, bringing fewer visitors and more affordable prices. Temperatures drop to between 43 and 55°F (6 to 13°C). This month typically sees an increase in rainfall, with an average of around 7.5 inches (19 cm).

September is ideal for activities like hiking and wildlife tours; however, be sure to wear warm clothing to stay comfortable in the chilly weather. Additionally, September is a fantastic month for cruising along Alaska’s coastlines, offering spectacular views from the water as the foliage shifts to vibrant autumn colors.

The changing foliage provides a stunning backdrop for hiking, especially earlier in the month. Berry picking and fishing are also popular during this month. Plus, the fewer crowds mean more peace and quiet as you explore the Alaskan wilderness.

Cruising Alaska in October

October marks a quieter time for Alaska cruises, with most cruise lines ending their operations by mid-month. Norwegian Cruise Line is one of the few larger lines offering sailings this month, with ships like the Norwegian Encore and Norwegian Jewel departing from Seattle for 7 to 9-night cruises. Due to the generally unfavorable weather, prices are lower, and you’ll encounter fewer crowds, making it an affordable time to visit.

The temperatures in October range from 38 to 47°F (3 to 8°C), and there’s a significant increase in rainfall, averaging 8.3 inches (21 cm). This month often sees the first significant snowfalls of the season, especially in higher elevations and northern regions. The weather can be quite unpredictable, with more rain and rougher sea conditions, but this also contributes to the lower prices and fewer tourists.

Alaska offers a more peaceful and quiet atmosphere in October due to fewer visitors. Norwegian Cruise Line provides cruises to stunning destinations such as Juneau, Skagway, and Glacier Bay, each especially beautiful during this time of year. In Juneau, you can explore the historic gold rush sites or kayak alongside glaciers. Skagway offers a chance to ride the scenic White Pass and Yukon Route Railroad, while Glacier Bay is perfect for whale watching and spotting the dramatic calving of icebergs.

When is the best time for an Alaska cruise?

If you’re planning an Alaska cruise, the best time to go depends on what you want to experience. For those looking for pleasant weather and long daylight hours, June, July, and August are ideal. These summer months offer temperatures ranging from 46 to 65°F (8 to 18°C), making it perfect for outdoor activities and sightseeing. Additionally, summer provides the best opportunities for wildlife viewing, including sightings of humpback whales, bears, and bald eagles. July is particularly ideal for brown bear viewing, as they can often be seen hunting for salmon.

If you prefer fewer tourists and lower prices, consider cruising in May or September, which are known as the shoulder seasons. These months still offer good weather and plenty of daylight, but with smaller crowds. For wildlife enthusiasts, May is a great time to see bears, moose, and migratory birds, while September and October are excellent months for spotting the northern lights.

Best Time for an Alaska Cruise: A Month-by-Month Guide – FAQ

What is the best time to see the Northern Lights on an Alaskan cruise?

The best time to see the northern lights on an Alaskan cruise is from late September to October. During these months, the nights are longer and darker, providing optimal conditions for viewing this spectacular natural phenomenon. While most cruise lines end their Alaska season by mid-October, late-season cruises or land excursions to places like Fairbanks offer the best chances to witness the aurora borealis.

What is the cheapest month to cruise to Alaska?

October is the cheapest month to cruise to Alaska due to lower demand and less favorable weather conditions. However, the conditions in October can be less ideal for sightseeing and outdoor activities. May and September (shoulder seasons) offer a good sweet spot with more favorable weather, fewer crowds, and still relatively low prices.

What is the best time of year for an Alaskan cruise to see whales?

The best time of year for an Alaskan cruise to see whales is from May to September. During these months, various species of whales, including humpback whales and orcas, migrate to the nutrient-rich waters of Alaska for feeding. Peak whale-watching opportunities occur in June and July, when the whale activity is highest and sightings are most frequent.

Can you see the northern lights on a cruise ship?

Seeing the northern lights on an Alaskan cruise is possible but generally unlikely unless the cruise is specifically designed for aurora viewing. The best chances for witnessing the northern lights on an Alaskan cruise are in late September or early October, when the nights are longer and darker. Remember that most Alaskan cruises typically run in the summer months when the northern lights aren’t visible.

What is the most expensive month for an Alaska cruise?

The most expensive month for an Alaska cruise is July. This is the peak of the tourist season, when the weather is warmest and there are the most daylight hours, making it a popular time for travelers. As a result, prices for cruises, accommodations, and excursions are at their highest.

Alaska cruise in May can be perfect! (pics!) + things to do 🏔 early May and mid-May weather and wildlife?!

Is May too early for an Alaska cruise?!

Well, surely it depends on what you’re looking for.

For example, it seems like May is still early for whale watching.

I still did see whales in May in several cruise ports, but it seems summer is more prime whale watching in Alaska.

And that goes for basically all wildlife.

Prime wildlife watching in Alaska seems to be in the summer.

So if wildlife watching is priority number 1 for you during an Alaska cruise, then May might be too early for you.

But otherwise…

If you are after Alaska landscape, then May can be a perfect time for an Alaska cruise!!

Before I left for my early season Alaska cruise, I had gotten the impression from reading things online that you actually have a better chance of better weather in May.

And, that is basically what happened.

The vast majority of my time in Alaska in May, there was good weather.

I was not really surprised, since I expected good weather by going to Alaska in May. 😂

So I was a bit confused when there were locals in several of the cruise ports who made it sound like good weather was unusual, even in May. 🤔

I asked a Glacier Bay National Park ranger about this, and she indicated that May in Glacier Bay tends to be one of the months that is more dry and sees more sun, so maybe I was just reading about Glacier Bay. 🤔

In any case, when I went to Alaska in May, the weather on the vast majority of Alaska days was pretty good.

Even Ketchikan, which the internet will tell you is always rainy, was sunny the 2 times I went in May.

And the one pretty terrible weather day I had in May, it was actually pretty funny because it was the first Alaska day I had, and it was super rainy, super windy, and super cold!

And so… it was like a perfect “welcome to Alaska!!!” 🤣

So I guess it’s true.

Anything goes in Alaska!

And that includes Alaska in May!

As “they” say, weather can change quickly in Alaska!

Pictures of Alaska in May

Of course, every year is different since it’s all weather dependent.

But here is what an Alaska cruise in May looked like in 2023!

May 2: Hubbard Glacier scenic cruising sea day

• May 3: Icy Strait Point
• May 4: Juneau
• May 5: Skagway

May 6: Glacier Bay National Park scenic cruising sea day

• May 7: Sitka
• May 8: Ketchikan
• May 15: Ketchikan
• May 16: Juneau
• May 17: Skagway

May 18: Glacier Bay National Park scenic cruising sea day

• May 19: College Fjord scenic cruising sea evening
• May 20: Whittier

I did 2 Alaska cruises in May:

• Alaska cruise from Vancouver round trip
• Vancouver to Anchorage cruise one-way

Another thing to consider for an Alaska cruise in May is that it might still be too early in the season to reach some spot because of ice.

It seemed like it was questionable if we were going to make it to Hubbard Glacier.

I think the captain had announced that our cruise ship was the first of the Alaska cruise season to go to Hubbard Glacier, so there were no ice reports.

But, we ended up being able to make it to Hubbard Glacier!

There was ice, but it wasn’t enough to keep the cruise ship from reaching Hubbard Glacier!

And, the ice on the way to Hubbard Glacier made it look really pretty!

Cruising to Hubbard Glacier means cruising through Yakutat Bay and Disenchantment Bay to get to Hubbard Glacier.

May 3: Icy Strait Point cruise port

My plan for Icy Strait Point cruise port:

• morning: Icy Strait Point whale watching tour ( Icy Strait Point Whale Adventures ) 8:45am to 11:45am
• afternoon: Walk around Icy Strait Point on my own 

Early May seems to still be early for whale season, so I wasn’t even sure if I’d have a chance to see whales.

The day before, it seems like they saw quite a few whales, but on the day I went it seems like there weren’t as many.

That’s okay, because I had managed my expectations since May wasn’t prime whale watching season in Alaska.

At the very least, it was boat ride in Alaska in May!

Still, I did get to see a whale tail pretty close from the boat, and it was my first time seeing a whale tail like that, so that was the highlight of the whale watching tour in Icy Strait Point!

May 4: Juneau cruise port

My plan for Juneau cruise port:

• morning + lunch: Taku Lodge Feast & 5-Glacier Seaplane Discovery with Taku Lodge Wings Airways (Princess shore excursion) 9:30am to 1pm
• afternoon + evening: Mendenhall Glacier and Nugget Falls on my own

May 5: Skagway cruise port

My plan for Skagway cruise port:

• morning: White Pass Rail & Klondike Highway (Princess shore excursion) 8:15am to 12pm
• afternoon: Glacier Discovery by Helicopter with Temsco Helicopters (Princess shore excursion) 2:15pm to 4:15pm

May 7: Sitka cruise port

My plan for Sitka cruise port:

• morning: Sitka marine wildlife tour with Sitka Sound Tours

Alaska Cruise Weather - What to Expect

Published: Jan 01, 2021 Last Updated: Nov 30, 2023

Though weather can be hard to predict, especially in Alaska, there are trends that’ll help you know what to expect during your summer cruise. So, check the weather before you pack, but these will give you a guesstimate.

The best time for an Alaskan Cruise is May through with September, with the best weather in June and July. In May and September, you can anticipate a few extra rainy days and slightly cooler (though still pleasant!) temperatures. Note that the best times for whale watching  are mid-June to mid-August, though you can catch them before and after this, too.

Here is the typical weather during Alaska cruise season:

Juneau Cruise Weather

The capital of alaska sees average highs in the upper 50’s and low 60’s in may through august, with september highs averaging in the low 50’s. it’s much less rainy than the previous two at 62 inches, but it’s still pretty common..

Juneau, AK ( Photo  /  CC BY )

Skagway Cruise Weather  

It’s a little warmer and a little less rainy in the land of infamous  Soapy Smith , with high averages in the upper 50’s and lower 60’s May through September and an average rainfall of 27 inches annually.

The best time to cruise Alaska

Alaska is a cruise destination with a limited season. Cruise ships arrive in southeast Alaska in spring, stay the summer and linger only into early fall. The 49th state's snowy, cold and dark winters are not conducive to cruising.

Most cruise passengers will head to Alaska between Memorial Day in late May and Labor Day in early September when temperatures range from slightly chilly to warm during the long daylight hours. Tourist attractions are in full swing, salmon swim upriver, and bears (and humans) have access to fishing.

Some adventurous cruisers will board ships when they arrive in Alaska in April to see the remnants of winter. A few big ships cruise into mid-October for those who want a peek at what life is like in Alaska towns when all other tourists have returned home.

Each month has its advantages, not the least of which is discounted pricing in the spring and fall shoulder seasons. Here is a guide to help you decide when to cruise in Alaska.

After a long winter, Alaska begins to wake up in April — that includes the wildlife. Small-ship cruise lines such as Lindblad Expeditions and UnCruise Adventures have sailings into the wilderness, where you might spot bears emerging from their slumber and admire huge waterfalls fueled by the snowmelt. A few big ships, such as Norwegian Cruise Line 's 4,000-passenger Norwegian Bliss out of Seattle , begin their season this month with discounted early-season pricing.

You may encounter freezing rain or even snow on your April cruise and should expect to tread through the mud. Some tourist facilities — including those at national parks — may still be shuttered for the winter.

On the other hand, you will have the opportunity to observe the change of seasons. Expect crisp mornings with temperatures in the 30s, though by the end of the month, you may find dry weather and temperatures in the 60s. As an added bonus, the skies will be dark at night; if clear, you might spot the northern lights.

As someone who has cruised Alaska many times, I love cruising in May when the weather is dry. Locals start emerging from their winter cocoons, embracing the sunshine, and the wildlife does the same. You might spot bears with their cubs, moose with their calves and humpback whales returning from their winter home in Hawaii.

Big-ship cruise lines such as Holland America Line , Princess Cruises and Royal Caribbean ramp up their operations in May, as do Disney Cruise Line and small-ship and luxury lines. Early season deals might be available.

Attractions and shops will switch to peak-season hours at the end of the month; Denali National Park and Preserve will switch into summer mode in May. You'll find those who work in tourism excited to be back in business, considering many people in southeast Alaska earn their income from out-of-state visitors. Cruise lines will offer the opportunity to extend cruises with land tours, which include accommodations, transportation and some meals.

While early May often carries a chill in the air, you might encounter temperatures in the 60s by the end of the month. The warmer weather means glaciers begin shedding ice more frequently, so you have a better chance of experiencing the sight and sound of a house-size chunk of ice calving into the sea. Another bonus is that Alaska's large mosquito population has yet to emerge.

The cruise season beefs up in June, with the number of ships growing; the season is in full swing by the end of the month. The midnight sun means many hours of daylight — especially on June 20, the longest day of the year. You'll have to stay up late to see any darkness at all.

Early in June, the ships still mostly carry adults, with the family crowd — including multigenerational groups — arriving later in the month.

Shore excursion experiences abound. Temperatures are pleasant — in the 60s and sometimes higher, with wildflowers in bloom and glaciers calving. Anglers will find opportunities to reel in halibut along with king and sockeye salmon and rainbow trout. In addition to humpbacks, you might also spot belugas and seals with their pups as you sail.

At the beginning of the month, you might still be able to find some early-season pricing; the peak season for Alaska cruising begins in late June.

July and August

Summer is the height of the Alaska cruise season, which means crowds in port towns, especially when several ships are in port at the same time. You might have to wait hours for a table at the popular Tracy's King Crab Shack in Juneau.

It might surprise many, but July and especially August are rainy, so don't expect endless sunshine. That said, you are in Alaska at a time for festivals and other special events, and frontier towns really come alive.

Temperatures will be in the 60s, sometimes higher — you might even see 80s in Juneau in July. During long days of light, you'll find hearty Alaskans swimming in the sea and enjoying water sports. Shore excursion options will be in full swing.

During both months, you will encounter peak-season pricing. Unless you booked early, cabin choice could be limited — especially if you are looking for a fancy suite or cheap inside cabin; those tend to be the first categories to sell out. Balcony cabins are particularly popular in Alaska.

Mosquitos enjoy the summer, too, so pack bug spray. July and August are also spawning season for salmon, so you might spot grizzlies and brown bears near rivers and streams.

Keep an eye out for seabirds and songbirds, seals, Steller sea lions and humpback whales. Marine life is so prolific that some small-boat shore excursions guarantee you will see animals. Bears will be fishing; in late August, they will be looking for blueberries, which also become a featured item on restaurant menus. Toward the end of August, you'll see leaves changing to fall colors.

The beginning of September is much like August, but after the kids go back to school and the family crowd departs, it's shoulder season for cruising and pricing drops. Most cruise ships will have repositioned out of the state by the end of the month. You will experience a change of season, with cooler temperatures (in the 50s or lower) and some rain.

Mid-to-late September is one of the best times to spot wildlife in Alaska. I have had extraordinary experiences. Once, I watched a pod of humpback whales gather together in bubble-net feeding (corralling fish in a "net" of bubbles) to fill their bellies in preparation for their annual journey to warmer waters. Bears will be hunting for the last of the berries and salmon, and caribou, deer and moose will be mating.

You'll see colorful fall foliage but not mosquitos. National park facilities and some tourist businesses will switch to winter hours. September is also a great time to get deals on souvenirs, as merchants sell off this year's goods at the end of Alaska's tourist season.

On clear nights, you have a chance of spotting the northern lights — though they won't shine as brightly as they do in winter. Rather than stay up all night, see if your ship or pre- or post-cruise hotel has a sign-up sheet for people who want a wake-up call should the lights appear.

A limited number of cruises in October (predominantly on Norwegian Cruise Line ) make it possible for cruisers to experience a taste of Alaska in winter without sub-zero temperatures. You will want to bundle up; the average temperature in Juneau in October is 39 degrees. Days will be short — there are only about 10 hours of daylight. You are likely to experience rain and maybe snow.

Some attractions and shops will be closed for winter, though your cruise line will still operate a full roster of shore excursions. On the plus side, you will experience southeast Alaska towns as they are most of the year, sans tourist crowds. Sit in a bar and talk to the locals as they prepare for the long winter ahead. Cruise fares will be discounted.

When is the best time to see the northern lights in Alaska?

If one of your primary objectives during your Alaska sailing is to get a glimpse of the northern lights , consider a sailing in late August, September or October. The lights are typically strong in Alaska from late August to mid-April.

Your best bet for a sighting will be in Fairbanks — it's situated under the "aurora oval," an area known for a high frequency of northern lights displays. Fairbanks is a popular stop on cruisetours, itineraries that combine time sailing with overnight stays on land. For example, Holland America's nine-night Denali itinerary begins with an overnight stay in Fairbanks in early September.

Denali National Park and Anchorage can offer a glimpse of the northern lights — though not as frequently as Fairbanks since they are farther south. Both destinations are popular cruisetour stops. If you're cruising into or out of Seward or Whittier, you'll fly through Anchorage on one end of your trip. Consider an extra night or two there if you want to try and catch the aurora.

It's incredibly rare to see the northern lights from aboard your ship in the Inside Passage.

What is the cheapest month for an Alaska cruise?

As previously mentioned, April, May, September and October are good months for an Alaska cruise if you're hoping to score a deal . In addition to cheaper fares, early and late sailings of the season see fewer crowds.

Bottom line

What is the best month for an Alaska cruise? Alaska is a thrilling cruise destination no matter which month you sail. However, some months might be better for you, depending on your interests. Look to the early and late sailings of the season if you are a bargain seeker. Choose a May or June sailing for drier weather and fewer mosquitos. Summer is the best time to cruise to see abundant marine life and birds. September can be a great month to see wildlife.

Frequently Asked Questions

The best time to cruise Alaska is in May or June, at the beginning of the cruise season. Alaska’s cruise season has always been short, peaking quickly at the height of the summer months and then done by early fall. But as the destination has grown in popularity, the season has extended, and there’s a definite sweet spot to target. In May and June, the days will be at their longest, the weather (although still unpredictable) will generally be its sunniest and driest, and the range of excursions and options at their most plentiful.

With that in mind, Alaska is still a dynamic destination—no one snapshot of time during the year is guaranteed to encompass all this state has to offer . There are always tradeoffs. Visit too early in the summer, and you'll miss the salmon runs (and the bears that come to feed on them); visit too late, and much of the wildlife that attracts summer visitors will have either started retreating for warmer climes or begun looking for a den to hibernate in for the winter.

Alaska’s weather is unpredictable, to say the least. There are days throughout the year when there can be a temperature swing of a hundred degrees on opposite ends of the state—50 degrees Fahrenheit in Sitka and 50 degrees below zero in Fairbanks , for example. May can be one of the finest months across Alaska, as daylight reaches near-summer heights, while June is even nicer, with the last chill of the arctic winter departing for the season.

The Official Visitors Guide for Juneau playfully uses a raindrop graphic for every month in the calendar (in Southeast Alaska it’s never a question of whether it will rain, but how much it will rain). Wetter weather often sets in during the month of July, getting progressively wetter going into autumn. Juneau averages 15 days of rain in June, reaching 21 days of rain by October. In Anchorage and the northern part of the state, the rain often turns to “termination dust”—i.e. snow—as early as late September.

The Alaska cruise season begins in mid-May, but it doesn’t reach full swing until after Memorial Day. Sailings departing earlier in the season will less frequently be sharing berth space in port with numerous other ships, meaning that crowds in the ports will be somewhat lighter. Later in June and through July, visitors will find themselves at the peak of the short season, when the maximum amount of cruise ships and land visitors all pour into small town centers and cycle through popular tourist attractions on a relentless schedule.

The maxim on Alaska cruises is that it’s best to book ahead to guarantee prime spots on shore excursions—although, with fewer travelers vying for slots in the shoulder seasons of May and September, that availability tends to sell out later. Wildlife tours, for example, popularly sell out of their early morning slots early, as this is an ideal time to see the wildlife before it gets exasperated with the streams of tourist buses and boats.

Offered by Princess Cruises and Holland America Line , fishing excursions that allow guests to have their catch prepared and served to them onboard the ship also sell quickly. Cruise goers set on this experience should check frequently with the cruise line regarding the anticipated permitted fishing season, as the catch is strictly limited or sometimes prohibited early on during the run, and the state’s regulations change frequently based on observed conditions.

When planning your cruise, the weather should be a consideration for many shore excursions. For example, flightseeing via fixed wing or helicopter is a popular way to see glacier fields and spectacular mountain vistas, but small aircraft are sensitive to weather conditions. Choosing to cruise during the dryer months of May and June can help give you a better chance at participating in these weather-dependent excursions, although of course there’s never a guarantee.

Alaska cruises are popular with multi-generational groups, and as such, North American school schedules tend to dictate pricing peaks. Price-conscious travelers will generally find price breaks before Memorial Day or after mid-August, when schools in many parts of the country will be in session.

Cruisers planning to sail from mid-June through mid-August should start looking at sailings up to a year in advance, particularly if there are stateroom or itinerary preferences (popular sailings that include stops in Glacier Bay or Icy Strait Point book quickly).

Another time to book is during the “Wave Season” during the first two months of the year, when cruise deals abound for all destinations. Alaska cruisers can also find good last-minute deals just a few months prior to summer departures, although the best availability for these deals is often during the May shoulder season, or for the last remaining staterooms or cruise tour slots for sporadic dates throughout the summer months. Last-minute deals are also most common on large-ship lines, including Cunard , Celebrity , Carnival , and Royal Caribbean .

Cruisers booking small-ship cruises like Uncruise Adventures or the Indigenous-owned Alaskan Dream Cruises should also plan to book far in advance, as the small capacity of the ships often limits availability on popular sailings.

The Best Time for Whale Watching

It depends on the species. Gray whales can be seen in Alaska waters as early as April. Orcas tend to migrate to (and concentrate in) Southeast Alaska in May and June, while humpback whales are at their peak in June and July. Beluga whales come later in the summer, following the salmon runs in Southcentral Alaska; the best place to see them is around Cook Inlet and the Gulf of Alaska from mid-July through August.

The Best Time for Viewing the Northern Lights

Generally considered a winter activity, the northern lights (or aurora borealis to be technical) are actually present in the upper atmosphere year-round—it’s just too light to notice them during the endless, sunny days of the Arctic summer. By August, it’s dark enough during the night to see the northern lights, and cruises in September afford the best chances with longer, darker nights—although it’s worth noting that September is one of Alaska’s rainiest months, so there’s more chance of cloud cover. That said, the routing of cruise ships away from shore and the light pollution of major cities affords some of the best conditions for northern lights spotting.

Key Events & Festivals

If you're extending your time in Alaska and planning a pre- or post-cruise itinerary, or you're simply looking for fun things to do at your ports of call, these are the top events and festivals to check out during peak Alaskan cruise season.

• In Anchorage, Summer Solstice is observed with a festival, which also coincides with Pride and Juneteenth, making the entire week feel like an endless parade. Visitors to Fairbanks—where the solstice day is a full 24 hours—will find a street festival and baseball game.
• Pride events can be found throughout Alaska in June, even in tiny Skagway, which has a year-round population of just 1,200.
• The Sitka Music Festival takes place through the month of June, with concerts and intimate chamber performances by visiting and local musicians.
• Every July 4 in Seward, competitors run a marathon, Alaska style—that is, up the side of the aptly named Mount Marathon . Throngs of crowds gather to watch and cheer on their favorites.
• Independence Day is observed throughout Alaska with fireworks and parades, most notably in Anchorage.
• Forest Fair is traditionally held in Girdwood, a progressive resort community south of Anchorage, the weekend after Independence Day.
• Off the cruise ship track (but worth a visit for visitors ending their trips in Anchorage with a day or two to spare), the Alaska State Fair is a supremely local gem, with famously gigantic vegetables, local arts and crafts, and a carnival midway that could be plucked right out of any all-American town.

May and June are the best months to go on an Alaskan cruise, as the weather will be at its warmest and driest, and you'll have the widest range of shore excursions available.

You can spot whales from April through August, although the type of whale you'll see will greatly depend on the month. Gray whales, for instance, can be found in April, while orcas appear around Southeast Alaska in May and June. In June and July, you can watch humpback whales, while beluga whales pop up in Southcentral Alaska from mid-July to August.

The best time to see the northern lights is in August and September, as the nights get longer and darker heading into winter. However, keep in mind that September is a particularly rainy month, so there's a chance that it will be too cloudy to see them.

Alaska Cruise Weather by Month

Alaska Cruise Temperature by Month

Whether soaking up the golden sun on a fishing expedition or feeling the crisp breeze as you zipline through picturesque landscapes, you may notice that on an Alaska cruise , weather can vary greatly month-to-month. Princess cruise itineraries travel to the Southeast and Inside Passage regions of Alaska from May through September when wildlife is bustling, greenery is flourishing and salmon are running. Temperatures can reach anywhere from the low 30s to upper 80s depending on your month of travel as well as the port of call. We always recommend that you dress in layers to prepare for whatever weather comes your way. To help you get ready for your awe-inspiring adventure, learn about Alaska cruise temperatures by month.

Alaska Cruise Weather in May

After spending the winter in warmer climates, humpback whales migrate north and break the waters of the Inside Passage, marking the dawn of Alaska’s most vivacious season. Hundreds of king salmon grace the majestic waters of the Pacific while freckled lynx bask in the early summer sun. Thanks to the modest daytime temperatures and refreshing evening climates, May is peak season for many of Alaska’s most cherished wildlife. Weather typically ranges from the -1 to a high of around 12 degrees Celsius. May itineraries invite guests to pack jumpers and jackets for easy layering.

Alaska Cruise Weather in June

Feel the warm embrace of the summer sun throughout June when the Land of the Midnight Sun experiences the height of its daylight. With over 18 hours of golden sun each day, Alaska landscapes kiss the snowy surfaces goodbye and welcome the lush green meadows that bear the fruits of winter’s labor. With newly dried surfaces, hiking expeditions commence. As you venture into the depths of Alaska’s wilderness, reach new heights where you can enjoy unparalleled views of staggering glaciers and roaming hillside wildlife. With lows around 5 and highs around 18, allow the revitalising, crisp breeze to tickle your neck as you rejoice in the unforgettable climb.

Alaska Cruise Weather in July

As temperatures continue to rise, relish in the warmest month of the year when Alaska’s wildlife comes out to play. In Icy Strait Point, find regal brown grizzly bears roaming through streams in search of fresh salmon. Or, look for lively humpback whales making a splash off the coast of Juneau. As you embark on your summer adventure, bring light jackets for hiking through shady regions as well as plenty of sunscreen for basking in 18 hours of glorious sunlight each day this month.

Alaska Cruise Weather in August

Cast your line into the marvels of an Alaska summer by cruising in August. As you sail into each port of call, delight your taste buds in the delicacies of Alaska’s waters. Donning subtle notes of the sea, the silver salmon is one of the most sought-after fish and just so happens to be most fruitful this time of year. Whether or not fishing is your forte, be sure to pack water-resistant apparel for every splash and sprinkle that may arise from kayaking down crystalline fjords and hiking through misty rainforests. With lows around 5 and highs of around 18, you’ll feel refreshed and eager to explore the captivating wonders of Alaska.

Alaska Cruise Weather in September

As September begins, the sun dips below the horizon signifying the inauguration of autumn. The lush green forests transition into vibrant hues of gold and saffron while the mountaintops become freckled in snowfall. Daylight quietly recedes and the growing twilight perfectly contrasts the luminous green lights of the Aurora Borealis . The enchanting colours invite you to marvel at the miracles of Mother Nature that so often act as the inspiration for treasured postcards. With only 12 hours of sunlight, temperatures range from around 6 degrees to around 12 degrees. These new, cooler climates encourage Alaska’s famed wildlife to begin preparing for hibernation. Gaze at the water’s surface as thousands of bald eagles congregate to enjoy the final salmon of the season.

Best Month to Take an Alaska Cruise

What is the best weather for an Alaska cruise? Temperatures can vary anywhere between 30 to 80 degrees throughout the summer travel months – inviting guests to layer on the jumpers and windbreakers as weather can be unpredictable. So, the best month to travel to the Great Land depends on what you want to do. For the fishing aficionado, consider May when king salmon reach their greatest appearance. If you prefer to explore the lush scenery by foot, wait until June when the sun has overcome the frosty terrain of the Inside Passage and trails are primed for adventures. Regardless of which month you choose to explore Alaska, you’ll encounter iconic marine life and embark on heart-stirring adventures when you set sail with Princess.

Understanding the Alaska Cruise Season

The cruise calendar: when can you sail.

Alaska’s cruise season typically runs from late April to September. The peak months for cruising in Alaska are June, July, and August when you can experience the best of what the region has to offer. During these months, you’ll enjoy extended daylight hours, milder temperatures, and a higher likelihood of spotting wildlife such as whales, bears, and eagles. If you prefer a quieter and more budget-friendly experience, consider sailing in May or September, although be aware that the weather may be cooler during these months.

Weather Patterns in Alaska

When planning your Alaskan cruise, it’s crucial to consider the weather patterns unique to the region. In the summer months of June, July, and August, Alaska experiences relatively warmer temperatures, with July being the warmest month. However, it’s essential to pack layers as the weather can change quickly, especially in coastal areas. Be prepared for rain at any time during the cruise, so having waterproof gear is advisable to ensure you stay comfortable while exploring the stunning landscapes of Alaska.

Factors Influencing the Best Month for a Cruise

When planning your Alaskan cruise adventure, several key factors can influence the best month for your trip. By considering these elements, you can maximize your experience and make the most of your journey.

Crowds and Pricing

In Alaska, the peak months of June, July, and August are popular among travelers due to extended daylight hours, milder temperatures, and increased wildlife sightings. However, with popularity comes larger crowds and higher prices. If you prefer a quieter and more budget-friendly experience, you may want to consider cruising in May or September. During these months, although temperatures might be cooler, you’ll likely encounter fewer tourists and potentially enjoy cost savings on your cruise.

Wildlife and Natural Spectacles

Alaska is renowned for its stunning wildlife and natural beauty. If observing diverse wildlife and experiencing breathtaking spectacles are priorities for you, opt for cruising during the peak summer months. June, July, and August offer increased chances of spotting iconic Alaskan creatures like whales, bears, eagles, and more. Keep in mind that the weather during these months can be more favorable for wildlife viewing, enhancing your opportunities to witness these incredible animals in their natural habitats.

Fishing Seasons in Alaska

For fishing enthusiasts, knowing the fishing seasons in Alaska can greatly impact your cruise experience. Different fish species have peak seasons throughout the year, providing unique opportunities for fishing enthusiasts to indulge in their favorite pastime. Depending on the types of fish you’re hoping to catch, the best month for your Alaskan cruise may vary. Research the fishing seasons in Alaska to align your trip with the ideal time for your preferred fishing activities, ensuring a fulfilling and exciting adventure on the waters of Alaska.

• Extended Daylight Hours : Experience the magic of the Midnight Sun, providing ample time for exploring even in the late evening.
• Optimal Wildlife Viewing : Spot whales, bears, and other wildlife in their active summer habitats.

While the high season brings fantastic experiences, there are a few considerations:

• Higher Prices : Expect elevated costs due to increased demand for cruises and tourist activities.
• Crowded Ports : Popular destinations may be busier, impacting the overall experience.

Late Season Advantages (September)

Cruise to Alaska in September for a more relaxed experience as the season begins to wind down. Consider the following benefits of a late-season voyage:

• Fall Colors : Witness nature’s spectacular transformation as the leaves start changing colors.
• Quieter Atmosphere : Enjoy a more serene journey with fewer tourists and a laid-back ambiance.

However, there are a couple of things to bear in mind:

• Cooler Temperatures : As autumn arrives, temperatures may drop, requiring you to pack layers for varying weather conditions.
• Reduced Wildlife Activity : Some wildlife species start to migrate or hibernate, affecting the frequency of sightings.

Plan your Alaskan cruise wisely, taking into account the unique highlights and considerations of each month to ensure a memorable and rewarding voyage.

What to Expect on Your Alaska Cruise

Onboard Experiences

When you embark on an Alaska cruise, you can look forward to a myriad of onboard experiences tailored to enrich your journey. Enjoy engaging lectures and presentations from naturalists and historians about the local wildlife, culture, and history. Immerse yourself in the Alaskan spirit with themed parties, live music performances, and entertainment shows that showcase the region’s unique heritage. Get pampered at the onboard spas or relax by the pool, taking in the breathtaking views of the Alaskan wilderness as you cruise along.

Shore Excursions and Land Tours

Exploring the shores of Alaska through shore excursions and land tours is a highlight of your cruise adventure. Venture into picturesque ports of call and partake in activities like whale watching, bear spotting, and hiking through lush forests. Experience the thrill of zip-lining over the treetops, kayaking amidst glaciers, or riding a vintage railway through stunning landscapes. Visit native cultural centers, museums, and quaint towns to gain insights into the local way of life and history, creating unforgettable memories along the way.

Glaciers and the Northern Lights

Witnessing the grandeur of glaciers and the ethereal beauty of the Northern Lights are defining moments of your Alaska cruise. Marvel at colossal glaciers calving into the sea, creating a spectacle of ice and water unlike any other. Capture the serenity of the icy landscapes as you sail through narrow fjords surrounded by towering walls of ice. In the evening, if you’re lucky, catch a glimpse of the mesmerizing Northern Lights painting the night sky with vivid colors, a truly magical experience that crowns your Alaskan voyage with wonder and awe.

Top Tips for Picking Your Cruise Month

Consider your cruise goals.

When selecting the ideal month for your Alaska cruise, think about what you want to experience. If you’re keen on spotting wildlife such as whales or bears, aim for May or June when the wildlife is more active. For a balance of good weather and wildlife viewing, July and August are your best bet. If you prefer a quieter, more serene voyage, September offers a more relaxed atmosphere and the chance to see the stunning fall colors enveloping the landscape.

Check Historical Weather Data

Before finalizing your cruise month, it’s crucial to check historical weather data for Alaska. Different months can vary significantly in terms of temperature and precipitation levels. It’s wise to be prepared for rain and cooler temperatures, especially in the early and later parts of the cruising season. July and August tend to offer the warmest weather, but also draw larger crowds due to the peak season.

Align with Special Events or Activities

If you have specific interests or want to partake in special events or activities during your Alaska cruise, consider aligning your travel dates accordingly. Various cultural festivals, wildlife excursions, and outdoor activities are organized throughout the cruising season that you may not want to miss. Research the events happening during different months to ensure you don’t miss out on anything that aligns with your preferences.

You now have a solid understanding of the best months for an Alaska cruise. Whether you’re seeking wildlife encounters, vibrant summer activities, or a more serene experience, there’s a month that fits your preferences. By considering factors like weather patterns, wildlife sightings, and personal interests, you can choose the ideal time for your Alaskan adventure. Remember to align your cruise goals with the unique offerings of each month to make the most of your experience. With careful planning and attention to detail, you’ll set sail on a memorable journey filled with breathtaking landscapes, exciting excursions, and unforgettable moments. Enjoy every moment of your Alaska cruise and create lasting memories that will stay with you long after you’ve returned home.

The Best Time to Cruise Alaska for Wildlife, Northern Lights, and Fewer Crowds

The best time to cruise Alaska isn't obvious—until you're quietly sailing along its calm waters under a cloudless, late-spring sky. It was on one such day that someone on board spotted a whale breaching. And then again. And again. Within minutes it seemed everyone on board had gathered at the railings on deck to watch. The captain of the ship nimbly repositioned us, giving both the port and starboard sides prime viewing, at a safe and respectful distance from the animals. With binoculars, cameras, and phones at the ready, the passengers and crew aboard  UnCruise Adventures'  86-guest  S.S. Legacy  settled in for what turned out to be an hour-long private show by a juvenile humpback who had migrated from Hawaii to spend the summer in the nutrient-rich Alaskan waters.

This is but one of the incredible experiences that may be had when visiting Alaska in the “secret season”—springtime. Not only are the flowers and plant life awakening from their wintertime slumber, so is its wildlife. Though the state’s more temperate summer season has long attracted its largest numbers of visitors, an increasing number of in-the-know travelers are looking to spring as the best time to cruise to Alaska , when they can count on fewer crowds—and increased savings—without sacrificing their chance to take advantage of the state’s landscape and  wildlife sightings .

On that same late-April voyage with UnCruise, the  Northern Lights  danced through the sky on night one, and through the week we spotted grizzly bear mamas and their cubs skirting the coastline; bald eagles soaring overhead; humpback whales and orcas breaking the water’s surface to breathe; puffins, seals, and sea lions bobbing in the water and laying out on rocks—even a wolf on the shoreline, feasting on a fresh kill. (Our captain said he had seen a wolf in Alaska only twice in his 30-year career.)

We sailed roundtrip from Juneau, and while I’ve visited the capital city during the busy summer months, I found the restaurants, bars, and shops much less crowded, reliably filled with locals for the most part. On the water, we rarely passed any other ships or boats, aside from fishermen out for their catches.

According to  Travel Alaska , cruising is the most popular way to explore the state, and Cruise Lines International Association Alaska predicts that 1.64 million cruise line passengers will sail to and within Alaska in 2024.

But when is really the best time to sail Alaska? We’ve broken the seasons down for you, including the highlights of each, as well as the best cruise lines and cruise ships to consider so you can make your bucket list dreams come true.

Celebrity Cruises’ Celebrity Edge sets sail for the first time in Alaska this year.

April and May

If your schedule allows, not only does sailing Alaska in April and May afford the possibilities of glimpsing the Northern Lights and seeing wildlife emerge from their winter hibernation, it’s a more affordable and less crowded time to cruise, too. April and May are also the driest months in Alaska, so the chances of rain are slim.

Norwegian Cruise Line kicks off the 2024 Alaska cruise season when Norwegian Bliss sets sail on a weeklong, roundtrip itinerary from Seattle; she will be the only ship sailing in Alaska the first two weeks of spring. Balcony cabins are still available on the season’s inaugural sailing at a discounted fare of $1,029 per person .

Smaller ships like those that comprise UnCruise Adventures ’ and Alaska Dream Cruises ’ fleets can maneuver closer to the coastline for better views of bears rambling along the beaches and on-land excursions without another soul around. Uncruise’s 12-night “Inside Passage” itinerary departs April 15 with rates starting at $6,300 per person , and Alaska Dream Cruises’ seven-night “Last Frontier Adventure” has starting rates from $3,995 per person .

June to August

Warmer temperatures, an average of 17 hours of daylight, and schools’ summer vacations all make Alaska a popular destination for cruising in June, July, and August. Expect crowded ports and more ships out on the water, but that’s not to say it’s not a good time to set sail: bears are still active, as are whales and native bird life.

Holland America Line, which has sailed in Alaska for 75 years, offers 50 itineraries throughout June, July, and August, including the new 28-day Alaska Arctic Circle Solstice itinerary that departs June 9 from Seattle; verandah staterooms start at $7,259 per person . Family favorite Disney Cruise Line offers 13 itineraries over the summer, including a seven-night itinerary from $3,467 per person .

Not only is school back in session in September, which means fewer crowds at ports, but the chances of seeing the Northern Lights return, especially if combining your cruise with a land tour that takes you further north into Alaska. Fall is also mating season for wildlife, so expect to see some friskiness.

Celebrity Cruises’ Celebrity Edge sets sail for the first time in Alaska this year and has four six- and seven-night itineraries in September, starting at $599 per person . For a cruise-tour option, Princess ’ 12-day Denali Explorer itinerary blends five days on land with a weeklong cruise with mini-suite rates from $4,008 per person .

The Alaska cruise season winds down in October, with only a few ships setting sail. Just as in April and May, you’ll likely have the water to yourself, and even fewer people in the ports you call upon. Along with cooler weather, you’ll also find lower fares that will please your bank account.

Just as Norwegian Cruise Line kicks off the 2024 Alaska cruise season in April, it’s the last cruise line to set sail in the state, and the only one to sail in October. The seven- and nine-day itineraries sail roundtrip from Seattle, and a recent search found fares more than 80% off published fares, starting at $499 per person .

What is the best time to cruise Alaska?

The summer cruise season in Alaska runs from mid-May to mid-September. Check out our quick tips for picking the best time to cruise Alaska , then read on for more details.

• May. Discounted shoulder season rates, more availability since not as many people are traveling, weather gets warmer.
• June. Long days, warmer temperatures, wildlife viewing, full access to shore excursions.
• July. Warmest month, good fishing opportunities, active glaciers.
• August. Cooler temperatures, fewer children traveling.
• September. Cooler weather, cheaper rates, more availability, smaller crowds, darker nights, chance to see northern lights on a corresponding land package.

May Alaska Cruises

In May, the state is transitioning from winter into summer. The temperature starts to rise, with highs in the mid-50s and lows in the 40s. May is also a drier month by Southcentral Alaska standards. There aren't as many travelers as the peak season, so if you'd like to avoid the crowds, this is a good start. You might also notice that many cruise lines offer lower prices in May than those for peak season. If you are traveling on a budget, cruise in May to take advantage of the discounted rates.

June Alaska Cruises

June is the first peak month for summer. Now into the busy months, cruise rates increase. The conditions tend to be warmer and drier in Southeast Alaska, and even places like Juneau and Ketchikan enjoy plentiful daylight. It's especially fun to cruise Alaska on the summer solstice (around June 22). Wildlife is abundant and active. A full selection of shore excursions is available to you. One tip: If you plan to take a land tour along with your cruise, schedule that portion for after June 4. The road into Denali National Park opens completely around the first week of June, and a wildlife bus tour into the park is not to be missed.

July Alaska Cruises

July cruisers enjoy the warmest weather, with highs around 65 degrees. Warmer weather also makes glaciers more active, so it's quite likely to see impressive calving events while cruising in front of Hubbard Glacier, or through the beautiful Glacier Bay National Park . If fishing in Alaska is on your bucket list, July is a good month to book a fishing trip during one of your shore days. Just like June, expect your cruise prices in July to be higher compared to the shoulder season.

August Alaska Cruises

August is the last peak month of the Alaska summer season. It is the rainiest month of the summer season, especially in Southeast Alaska, with Juneau averaging about 16 days with precipitation. Packing a good rain jacket and waterproof shoes is all it takes to make rainy port days enjoyable. Mature travelers who'd like a more adult-centered experience often choose to wait until the middle or end of August to cruise, when most kids are back in school.

September Alaska Cruises

September weather is much like August. Cruise lines typically lower their prices in September, so if you are traveling on a budget, September is a great time to cruise. Perhaps the best reason to cruise in September is a chance to see the northern lights . Nights are dark again, and while your chance of seeing them in Southeast Alaska is low, taking a land tour package along with your September cruise gets you farther north into Aurora Borealis country. Another reason to consider cruising in September is the smaller crowds.

No matter what you decide is the best time to cruise, keep this one thing in mind: Alaska is spectacular no matter the month.

How To Pick The Best Time of Year to Cruise to Alaska

Read our tips for the best times to cruise to Alaska. Find out when the best weather is, when to see the Northern Lights, or glacier calving and more!

The best time to cruise to Alaska is a matter of personal preference. The "best time" could be different for a solo cruise traveler who dreams of photographing bears than it is for a parent who wants a family vacation in the great outdoors. From May to September, the Alaska cruise season is just five months long, although Holland America Line offers Alaska cruises in  late April and early October .

Read on for the best time of year to cruise to Alaska, based on your personal preferences and the breathtaking experiences you want to check off your bucket list.  

Best Months For An Alaska Cruise With "Good" Weather

Tell a sun-worshiper that you’re taking an Alaska cruise and they’ll raise an eyebrow. Yes, it’s chilly. Yes, even in summer. On average in July, Alaska boasts high temps in the mid-60s, but occasionally climbs into the 70s and 80s. It’s also misty and drizzly. However, if you prepare for Alaska’s chill and damp weather, no matter what time of year you visit, you’ll have a great time. Bring a jacket, gloves, and scarves, along with waterproof gear, and sunscreen. Read  how to pack for an Alaska cruise  to stay comfortable in changing weather.

The most temperate  Alaska weather  is in July, then June and August when it’s warmer (though again, not near tropical) and drier. When it comes to May vs. September, May is slightly cooler, but gets significantly less rainfall. Temps can vary greatly depending on where you are in the state.

Best Months To Cruise Alaska For Midnight Sun

Alaska basks in gorgeous 24-hour daylight during two months of the year surrounding the summer solstice. This is when Alaska residents get their outdoor activities in, including 2:00 am hikes, dog walks, and beach volleyball. Mid-May through mid-July are the best months to cruise to Alaska to soak in the midnight sun.

Best Time Of Year For The Northern Lights

Winter, when nights are long, dark, and clear, is the best time to see the Northern Lights in Alaska. That said, it is possible but not guaranteed to see them on an Alaska cruise. An Alaska cruise in early April, or late September, close to the fall equinox (September 21), will increase your chances. Where you are matters too and the farther north, the better.  

Best Time Of Year For Glacier Calving

Ice calving is both a thunderous warning of climate change and an incredible phenomenon to behold. The best time to view artic-blue ice plunge into the sea is during the warmest months of June, July, and August at active glaciers.  

Best Time For Avoiding Tourist Crowds In Alaska

Spring, before school lets out, is the best time to cruise to Alaska with extra elbow room, shorter lines, and peaceful meals. You’ll still see amazing sights, like Dall sheep and other creatures who emerge from the mountains to graze verdant fields. Bonus: there are less mosquitoes in spring than summer.

Best Time To Cruise To Alaska For Wildlife

Bald eagles soaring overhead. Alaskan brown bears scooping up salmon from a rushing waterfall. A pod of orcas spyhopping in the ocean. Nature is in full bloom during cruise season in Alaska, but what you’ll see depends on the time of year and location.

At all times during cruise season, you’ll meet some of Alaska’s wild residents: eagles, whales, dolphins, and bears. Want to get up close and personal? The best and safest way to experience Alaska wildlife is through one of our guided Alaska  shore excursions .

Here are some of Alaska’s most fascinating creatures and best the times of year to see them:  

Nesting Eagles

About 30,000 eagles call the Great Land home and they’re more abundant in Alaska than anywhere else in the United States. There’s a good chance you’ll see eagles perched high near the shoreline, in town scavenging garbage dumps, or even feasting off a salmon run. Bald eagles hatch and rear young in April and you can see their mottled fledglings from May through June. Bring binoculars; eagles like to nest high.  

Bears Feeding On Salmon

Witnessing bears catch (or try to catch) slippery salmon from a river is one of the most incredible Alaska experiences you can have. The best time to view this dramatic display is mid-July to mid-August, though you can take  wildlife excursions  to bear hangouts at any time during cruise season.

Salmon Runs

Don’t underestimate fish. Salmon have a fascinating, beautiful life cycle well worth viewing. When they’re fully mature, millions take a harrowing upstream journey from the ocean to the rivers where they were born. The few who make it spawn and die here. Salmon runs in Alaska start in early May until September, with different species of salmon running at different times of year.  

Newborn Moose

Fuzzy baby moose, called calves, are as cute as it gets. Late May and early June are the best possible times to view a momma moose and her calves in Alaska. Moose can be dangerous, especially a threatened mom. If you do see these majestic creatures hulking around, stay far back (at least 50 feet) and never disturb a lone calf, as mom is somewhere nearby.  

Whale Watching

Alaska has humpback whales, gray whales, killer whales, and a small population of belugas. Though it’s species-dependent, the best time to go  whale watching in Alaska  is in high summer, when the days are long and the feeding is plentiful. And it all depends on what species you intend to see—humpbacks are in the area year-round, while others like gray whales migrate to Alaska in summer.

The best time for an Alaska cruise? Anytime. Alaska will steal your heart during every month of cruise season, so don’t overthink it and just enjoy. Happy planning!
