Imagine emerging from months of cold and darkness into a world where the sun lingers longer each day, the air softens, and nature awakens with vibrant energy. This is May in Alaska. While winter has its charms, May marks a dramatic shift, signaling the true arrival of summer. By mid-month, places like Anchorage bask in nearly 17 hours of daylight. Alaskans and visitors alike feel a palpable surge of energy, eager to explore the thawing landscapes. Planning your Trips To Alaska In May offers a unique blend of advantages and opportunities.
What to Expect: Alaska Weather in May
The contrast between early and late May in Alaska is striking. At the beginning of the month, landscapes might still show remnants of winter, with bare trees just hinting at green and temperatures hovering in the upper 40s to low 50s Fahrenheit. However, typically around the middle of May, a rapid transformation occurs. Trees begin to leaf out, temperatures climb closer to the 60s, and the feeling of summer truly takes hold across the state.

This transition point around May 15th is significant. Many summer tour operators choose this date to commence operations. Visiting earlier in May comes with advantages, primarily fewer crowds compared to the peak months of June and July. Additionally, May is often one of the driest months, potentially meaning less rain during your visit. The trade-off is that if you plan your Trips To Alaska In May before the 15th, you might find that some desired tours and activities are not yet available.
Packing for Your May Alaska Adventure
Layering is absolutely key for Trips To Alaska In May. The weather can change rapidly, and even within a single day, you might experience sunshine, cool breezes, or even a light shower. Begin with a moisture-wicking base layer, add insulating layers like fleece or wool, and top it off with a waterproof and windproof outer shell.
You’ll especially appreciate having a warmer jacket, such as a lightweight puffer, along with a hat and light gloves. These items are essential for early morning excursions or any tours that take you onto the water or onto a glacier, where temperatures will feel much colder. Comfortable, broken-in walking shoes are a must, and consider waterproof boots if you plan on exploring potentially wet or muddy trails.

Migratory birds also return in droves from epic journeys. Birding festivals across the state, like those focusing on shorebirds, celebrate this incredible phenomenon. May is also a prime time for whale watching as orcas and humpbacks arrive in Alaskan waters, following the earlier arrival of gray whales in March and April. If bear viewing is a priority, fly-in tours typically become available around mid-May to see bears foraging and tending to cubs.
Scenic Flights & Cruises
Taking to the air or water offers spectacular perspectives during your Trips To Alaska In May. Flightseeing tours, which operate year-round, are an excellent option even in early May, providing breathtaking views of mountains, glaciers, and coastlines as they shed their winter coats. Day cruises are also among the first summer activities to become available, offering chances to see marine wildlife and stunning coastal scenery.
By the middle of May, most other tour and activity operators have opened their doors. This includes a wide variety of excursions ranging from glacier walks and kayaking trips to cultural tours and adventure activities. The shoulder season means that while most options are available after May 15th, they are often less crowded than during the peak summer months, enhancing the experience.
Exploring National Parks
National Parks in Alaska are beginning to thaw and open up in May. While some higher elevation areas or trails may still be inaccessible due to snow, lower elevation and south-facing areas often become navigable. It’s a time to see the parks transitioning, with rivers and lakes thawing and vegetation starting to emerge. Visitors should always check park conditions and trail reports before heading out.
When exploring parks or trails, particularly in areas known for bear activity, exercising caution is crucial. Bears are emerging from hibernation and may be groggy or protective, especially sows with new cubs. Making noise on the trail and carrying bear spray are recommended safety precautions. If your goal is extensive mountain hiking on snow-free trails, June or July might be better suited for your Trips To Alaska In May.
Hiking & Trails
Hiking opportunities during Trips To Alaska In May depend heavily on elevation and location. Lower elevation trails, particularly those on south-facing slopes, are often the first to clear of snow and dry out. However, many trails, especially at higher elevations or in shaded areas, will still be covered in snow or be very slushy and muddy as the ground thaws.
If mountain hiking is a priority, you might find conditions challenging in May and may prefer to wait until later in the summer when trails are drier and more accessible. For May visits, focus on coastal trails, park roads that have opened, or lower-level wooded paths. Always be prepared for wet conditions and potentially encounter wildlife.
Fishing Opportunities
May marks the beginning of several exciting fishing opportunities in Alaska. Ocean charter companies start taking anglers out to fish for halibut, a popular target. Additionally, the king salmon fishing season typically begins in May in many areas.
Whether you’re an experienced angler or looking for a guided experience, booking a charter can be a fantastic way to spend a day on the water during your Trips To Alaska In May, combining the thrill of fishing with scenic views of the Alaskan coastline. Be sure to check local regulations and seasons, as they can vary by location.
Other Activities
Beyond wildlife and popular tours, Trips To Alaska In May can include other experiences. Many campgrounds and RV parks begin to open around Memorial Day weekend, although the exact dates depend on winter snowfall. Some private facilities may open earlier. Check with Alaska State Parks or private operators for specific opening dates.
For those interested in exploring off-the-beaten-path routes, roads that are not maintained in winter, like the Denali Highway and McCarthy Road, are generally declared open by mid-May. However, road conditions can still be variable early in the season, so it’s wise to check the latest reports before embarking on these journeys.

Logistics: Getting Around & Staying
When planning your Trips To Alaska In May, consider transportation options. Most major motorcoach and rail services that cater to summer tourism begin their routes by May 15th. Traveling during this shoulder season can sometimes offer better availability and potential discounts compared to peak summer.
If your trip falls in the first week or two of May, renting a car is often the most reliable way to get around and access different areas, as not all public transport or tour shuttles may be fully operational yet. For accommodations, hotels in larger cities like Anchorage and Fairbanks are typically open year-round. However, lodges and hotels in more remote or seasonal areas often open in early to late May. Some may offer “shoulder season” rates, but always verify that the activities you’re interested in nearby are also available. Alaska is a vast state, and having a good map or reliable navigation is essential.
Dealing with Bugs
While May is generally not the peak season for mosquitoes in Alaska, their numbers do increase as the month progresses and temperatures rise. If you plan on spending time outdoors, particularly hiking near ponds or standing water, investing in quality bug spray is recommended, especially towards the end of May. Early May typically sees very few biting insects.
Planning Your Trip To Alaska In May: Key Considerations
The primary factor influencing your experience during Trips To Alaska In May is whether your visit falls in the early or latter half of the month. The period before May 15th offers fewer crowds and dry weather but limited tour and activity options. The period after May 15th sees the vast majority of summer operations commence, opening up access to more experiences, though with slightly increased bug activity and potentially more people. Decide which set of priorities aligns best with your travel style.
