The best time to cruise Alaska

May to September.


The Alaskan cruising season is from May to September as this is the warmest time of year. Although warm, it is also notorious for rainfall, so pack accordingly.

Ships generally don’t sail to Alaska outside these months due to the icy weather conditions. But if you're concerned about weather affecting your trip, make sure you have the right cruise insurance so you may be able to claim compensation for altered itineraries or missed ports.


Experiencing four seasons, Alaska's summers are mild with temperatures of around 20℃ and its winters are often cold and harsh with temperatures of between -11℃ and -1℃.

Alaska is a popular destination for cruisers worldwide. Peak cruising season is from mid-June to mid-August as June is the hottest month of the year and these are the months when the Northern Hemisphere is on summer break.

The shoulder months of May and September tend to be quieter and cheaper. They feature spring wildflowers and autumn foliage, respectively.
