Why May is a unique month to cruise Alaska?

May is an ideal month to start your Alaska cruise adventure, offering unique benefits that set it apart from the busier summer months. Cruising in May means fewer crowds. You also have a wider choice of cabins and often more affordable rates compared to peak season.

The landscapes come alive as spring unfolds, with snow-capped mountains, lush green valleys, and the first wildflowers. Wildlife activity is high— especially for whales, and eagles begin to emerge and thrive, making this an exciting time for nature enthusiasts.

The weather in May is brisk but not as cold as winter, and the days are noticeably longer, giving you more time to explore Alaska’s rugged beauty. May’s crisp air is perfect for watching glaciers, without the sweltering sun you might find in midsummer.

With this early-season timing, you get a refreshing blend of quiet, natural beauty and thrilling wildlife encounters that make May a standout month for Alaskan cruises.

Chris and I love cruising Alaska and have experienced the stunning Last Frontier in nearly every month of the season. From the lush landscapes of early summer to the vibrant colors of fall, each month offers something unique—but May stands out as one of our favorites.

Weather Overview for an Alaska Cruises in May

In May, Alaska’s weather can be as dynamic as its landscapes, so it’s essential to be prepared for varied conditions. May temperatures generally range from the mid-30s to low 50s °F (1-11 °C), with average highs in the upper 40s to mid-50s °F (8-12 °C).

Mornings and evenings are often chilly, while afternoons can warm up, especially as the month progresses​. Here are details for the most popular Alaska ports of call.

Temperature Ranges

• Juneau: Expect daytime highs around 58°F (14°C) and lows dipping to 40°F (4°C), making layered clothing essential for comfort. Early mornings and evenings can feel brisk, especially near open water.
• Skagway: Similar to Juneau, Skagway sees average highs of 59°F (15°C) and lows of 42°F (5°C). However, it’s generally less humid, making cool evenings feel slightly milder.
• Ketchikan: With highs of around 55°F (13°C) and lows near 42°F (5°C), Ketchikan’s weather is somewhat milder but often damp, given it’s known for frequent rain.
• Seward (130 miles south of Anchorage): Highs in Seward average around 53°F (12°C), with lows around 37°F (3°C), keeping the coastal air crisp and cool, especially on breezy days.

Rain and Precipitation

May is a relatively dry month for Alaska’s cruise ports, especially compared to summer.

• Juneau receives about 4.1 inches (105 mm) of rain over approximately 14-18 days, often as light showers rather than heavy storms.
• Skagway experiences the least rain among these ports, with only around 1.3 inches (33 mm) on average.
• Ketchikan, however, is rainier with about 8.7 inches (220 mm) over 15-20 days—packing waterproof gear is a must here.
• Seward sees roughly 3.5 inches (89 mm) of rain across 12-15 days, so brief showers are common.

Snow and Seasonal Melt

In higher elevations, snow can linger into May, particularly early in the month. Juneau, for example, may still see snow in areas above sea level, enhancing scenic views with frosty peaks even as the snow melts in lower areas.

On rare days, cruise routes toward glaciers, such as Hubbard Glacier or Glacier Bay, may encounter floating icebergs early in the season, though it typically won’t impact ship access.

Daylight Hours

May brings longer days with about 17 hours of daylight by month-end. In Juneau, sunrise starts as early as 5:00 am, and by late May, sunset can stretch until nearly 10:00 pm. This extended daylight is perfect for sightseeing and maximizes shore excursion time, giving a relaxed pace to enjoy Alaska’s rugged scenery.

Pros of Cruising Alaska in May

What are the advantages of cruising to Alaska in May? Here is a detailed breakdown.

Fewer Crowds and Lower Prices

• Early Season Savings. May is the start of Alaska’s cruise season, and prices are generally lower than during peak summer months. Lower demand translates into savings on both cabin rates and excursions, making it an appealing option for budget-conscious travelers, as the cost of cruising to Alaska can be quite high.

• Upgrades. Guests cruising Alaska in May may find a pleasant surprise—upgrades! With fewer travelers onboard in early season, some cruise lines offer complimentary or discounted upgrades to higher cabin categories to fill available space.

• Less Congestion. May sees fewer tourists in popular ports like Juneau, Sitka, Icy Strait Point, Haines, Ketchikan, Skagway, Seward, or Whittier, allowing for a more relaxed, less crowded experience at top attractions and during excursions.

• Fewer Families and Children. With May being before summer vacation, there are typically fewer families and children on Alaska cruises. This early-season timing creates a quieter, more relaxed atmosphere onboard, ideal for those looking to explore Alaska without the high energy of peak summer family travel.

• Discounts. Some shore excursions in May may offer better, discounted prices due to early-season demand.

Exceptional Whale Viewing

May is prime time for whale watching in Alaska. Humpback whales and orcas migrate to Alaskan waters, and it’s not uncommon to spot them breaching near the cruise routes. This early-season migration creates thrilling opportunities for whale enthusiasts. We have a detailed article with tips about whale watching on Alaska cruise.

Snow-Capped Peaks and Melting Glaciers

May offers a unique contrast as Alaska transitions from winter to spring. Snow still blankets the higher mountain ranges, creating stunning scenery, especially in fjords like Tracy Arm, where icebergs and frosty peaks dominate the landscape.

This adds a layer of beauty to glacier viewing compared to the greener summer months. In May, you’ll get the unique experience of seeing Alaska’s snowy mountain peaks and icy landscapes without enduring the intense cold of winter.

Mild Weather with Less Rain: May is Drier Than Summer

May is among the driest months in Southeast Alaska. While some rain is likely, especially in Ketchikan, overall precipitation is lower compared to the heavier rains typical of summer. This more predictable weather allows for clearer views and more comfortable outdoor activities​.

May’s temperatures, though brisk, are generally comfortable with average highs in the upper 40s to mid-50s °F (8-12 °C).

Extended Sightseeing Time

By May, Alaska’s daylight extends to almost 17 hours, giving travelers ample time to explore and participate in activities without feeling rushed. Late sunsets make it easier to enjoy evening excursions, scenic cruising, or soak in the views from your cruise ship.

Cons of Cruising Alaska in May

Are there any downsides to cruising Alaska in May? Yes, there are, and it’s important to know what to expect before booking. We’ve explored Alaska in May multiple times and love its early-season charm, but there are specific limitations you should consider.

Here, we’re sharing an honest look at the potential cons of cruising in May, so you can decide if this month is the right fit for your Alaskan adventure.

Land Tours Are Limited in Early May

Combining a cruise with a land tour in May, especially in the first two weeks, can be challenging since certain destinations are still closed. For example, Denali National Park doesn’t fully open until around May 20.

If you’re cruising from Seward, remember that access to popular land destinations like Denali can be limited early in May. And for those departing from Whittier, planning a pre- or post-cruise land tour may require flexibility, as many iconic areas are only fully accessible from late May / mid-June onward.

Limited Access to Certain Activities

• Restricted Backcountry and Park Access: Many land-based activities, particularly in areas like Denali National Park, are restricted in early May as snow melts. Denali, a top attraction for land tours, generally opens to visitors around May 20, so combining a land tour with a cruise in early May can be challenging.
• Delayed Start for Fishing and Other Summer Tours: While May kicks off whale watching, salmon fishing and certain summer-specific excursions don’t peak until June or July. For those set on fishing or participating in Alaska’s summer festivals, a later cruise may be more fulfilling.​

Limited Wildlife Sightings Compared to Later Months

• Salmon-Related Wildlife is Scarcer: The famous salmon runs, which attract bears and other wildlife in large numbers, happen later in the summer. For travelers hoping to catch bears fishing for salmon, late June or July and August might be a better choice.
• Bear Viewing: May isn’t the best month for bear sightings, as the peak season for viewing bears begins in June. During the salmon run in areas like Ketchikan, sightings increase significantly in July and August when bears gather along rivers to fish.
• Katmai National Park and Brooks Falls: For those dreaming of the iconic bear-viewing experience at Brooks Falls in Katmai National Park, where bears catch salmon in mid-air, the peak season is late June through August. Planning a land tour to Katmai alongside a May cruise may not fulfill this specific wildlife goal​.

Rougher Seas Early in the Season

• Unsettled Waters: May’s transitional weather can create rougher seas, particularly in open areas like the Gulf of Alaska. Travelers prone to seasickness might consider Inside Passage routes, which are generally calmer, or bring anti-motion remedies.

Limited Onboard and Excursion Availability

Certain amenities may not be fully available early in the season, such as outdoor pools or specific summer-focused programs. Checking with the cruise line in advance can help align expectations​.

Limited Restaurant and Shop Availability

In early May, some restaurants, shops, and seasonal businesses in Alaskan ports may still be closed or have limited hours as they prepare for the busier summer months. This can affect dining and shopping options, especially in smaller ports where businesses typically open gradually as visitor numbers rise.

Unpredictable Weather Conditions

Variable and Cool Temperatures: May weather in Alaska can range from chilly mornings and evenings in the 40s °F (around 4-5°C) to mild afternoons in the low 50s °F. Coastal areas often experience rapid weather changes, so layers and rain gear are essential​.

Who We Recommend an Alaska Cruise in May?

An Alaska cruise in May is well-suited for those who enjoy nature, history, and more peaceful travel experiences, all at a lower cost. It’s a month full of seasonal transitions, making it perfect for flexible, nature-loving travelers seeking a unique Alaskan adventure.

Who We Do Not Recommend an Alaska Cruise in May?

• Those Looking for Full Access to Summer Activities and Alaska National Parks
• Travelers hoping to combine a cruise with a comprehensive land tour (especially in early May)
