The best time to visit Alaska

Cruising in Alaska during the summertime is a truly singular experience. Visiting between May and September sets you up to see the best of flora and fauna — as well as the most wildlife — under the warm sunshine, with all the amenities of a Princess Cruises® vacation. 

These are a few of the top reasons why summer is the best time to cruise Alaska.

Peak wildlife viewing

Summer offers opportunities to see amazing animals in Alaska. For lovers of marine life, the best time to cruise Alaska for whales is in summer. In April and May, gray whales migrate north and are often spotted from Alaska cruise ships. These whales are massive and can weigh up to 40 tons — which is about the equivalent of 60 cows! 

May and April bring the perfect opportunity to witness orcas, highly intelligent and social porpoises, thriving in our nutrient-rich waters. Their language and 90-year lifespan rival human complexity. However, their appearances become even more frequent with the summer arrival of Chinook Salmon.

As early as April and May, humpback whales start to migrate to our waters, replacing the orcas as the main attraction by June. Renowned for their haunting underwater songs, these gentle giants put on a breathtaking show. On top of that, some lucky visitors can spot the occasional blue whale or sperm whale. You might even see a white beluga whale peeking above the surface. 

Meanwhile on land, the summer months are when bears, moose and deer concentrate around streams and are often visible from the roadside. Grizzly and black bears stay close to the rivers because salmon start spawning from July to November. June is the best month to spot unusual birds such as Asian accidentals in western Alaska. This is the time when these beautiful birds take advantage of the long summer days to raise their young. July is the best month to visit seabird colonies from Southeast to Northwest Alaska. 

The summer is also when fur seal pups are born, so you might get lucky and spot one of the cute new babies. You can expect to see sea lions and even walruses lounging on the shores or diving through the waves.

During Alaska's summer, the entire landscape is bright green and lush — fields of wildflowers, Lupine and Fireweed sit next to alpine lakes and pine forests. When you visit in the summer, you get the best of Alaska’s flowers and plant life.

Lengthened daylight

Imagine sunshine all day long! In summertime, Alaska is known as the “land of the midnight sun” because of its lengthened daylight due to its high latitude. In fact, in northern Alaska, the community of Barrow gets a full 24 hours of daylight on the summer solstice. Near Fairbanks, Alaska's 'Land of the Midnight Sun', 19 hours of daylight fuel our chef's garden at Fairbanks Princess Riverside Lodge, bringing fresh flavors to our garden-to-table cuisine.

These long days mean more time to explore and take in the scenery around you. The sun won’t even truly set and you’ll enjoy a dusk-like sky during the middle of the night.

Ideal temperature

When you visit mainland Alaska during the summer, you’ll enjoy  ideal temperatures, with daytime highs between 60 and 70 degrees. It's the perfect atmosphere to go exploring without breaking too much of a sweat or getting sunburned. The summertime is also one of the driest seasons of the year, with only 25% chance of rain on a given day. 

During winter, fall and even spring, it can be quite cold and snowy in Alaska. In the winter, it sometimes gets below zero and will be dark almost the whole day. While Fairbanks has 19 hours of daylight in the summer, it has fewer than four hours during the winter.
