Best Season For An Alaska Cruise

Low season

If embracing peace and quiet is top of your list, then opt for cruising in the low season, which includes May and September. Because this is during school term-time, you’ll see less families and more couples and solo travellers, meaning excursions will be less crowded. However, due to the unpredictable weather during these months, be aware that some excursions may be postponed.


High season

With warmer weather to encourage wildlife and flora to truly flourish, June, July and August are the most popular months to cruise to Alaska. You’ll see a wider range of marine life which makes the high season especially appealing for fishing fans, although it’s wise to keep in mind that July and August can be quite wet.

Best Time To Cruise Alaska: Top Tips

No matter when you choose to embark on your Alaska cruise, there are some tips that will be useful to keep in mind all year round.

1. Pack sensibly

The weather in Alaska is incredibly unpredictable, even when visiting during the summer season. Rain can arrive at any moment, so keep a lightweight waterproof jacket in your bag at all times. Waterproof daypacks are also a great investment to keep your belongings safe and dry. Finally, pack plenty of layers! It’s better to be too warm and take layers off than be too cold and have nothing left, but keep your luggage allowance in mind at all times.

The essentials we recommend are:

  • Thermal base layers
  • Waterproof jacket
  • Waterproof trousers
  • Sturdy hiking shoes
  • Sun screen
  • Insect repellent

2. Combine your cruise with a hotel stay

Alaska is a huge state with an endless list of sights, activities, food and culture to explore. If you’re eager to get the most out of Alaska in one trip, opt for Cruise & Stay. This will give you time at the start or end of your cruise to continue your adventure inland, and can even be combined with a railway journey such as the Rocky Mountaineer.

3. Be respectful of wildlife

There are endless opportunities to get up close to Alaska’s wildlife in its natural, untouched habitat, but you must remember to keep your distance. Being disturbed can be very distressing for animals, particularly when their young are present. Opt to explore the wilderness with a qualified guide who can enhance your experience safely and respectfully.

4. Invest in good quality camera equipment

As well as the fascinating wildlife, Alaska boasts epic scenery, including snow-capped mountain ranges, miles and miles of colourful trees, vibrant blue glaciers and quaint coastal towns. You won’t want to forget any of these sights, so bring a sturdy camera with a telephoto lens, which will allow you to photograph subjects that are further away. Remember to bring spare batteries and memory cards too.

Best time to cruise to Alaska for glaciers

Though the best time to cruise Alaska depends on your own preferences, you can be sure that your chances of seeing breathtaking scenery, fascinating wildlife and vibrant culture are high. Cruise ships tend to stay close to the shore, meaning that you will be able to see all kinds of flora and fauna from the ship, with minimal effort, while adventures onshore will bring you to the very heart of the destination. All that remains for you to do is keep your camera nearby! Check out our range of Alaska cruises and discover your next dream cruise holiday.
