Best time to cruise Alaska: Help readers choose the ideal time to visit based on their interests and priorities

From May to September, the Alaska cruise season is only five months long, although some cruise lines operate from late April to early October.

Having said that, the best time to cruise the Last Frontier is entirely a matter of personal preference. It could be different from someone traveling solo wishing to photograph wildlife than for a parent who wants to take the kids to an outdoor family vacation.

So read on in order to understand the best time to cruise to Alaska. But before booking your cruise, consider not only the period that suits you but the breathtaking experiences you want to tick off your must-see list as well.

Best good weather months to cruise Alaska

Alaska is a chilly destination no doubt, as even during peak summer in July, the temperature hovers around the mid-60s and only occasionally reaches the mid-80s.

May is slightly cooler but receives much less rainfall compared to September, which sees a high of 56 F and around 8.5 “ of rain.

August sees warm temperatures in Alaska. So, if you want to enjoy lush green landscapes with manageable rainfall, you should go there in August.

Best weather for Midnight Sun

From mid-May to mid-July, Alaska is blessed with 24 hours of daylight surrounding the summer solstice. During this two-month window, outdoor activities like dog walks, and 2 am hikes are in full flow. These are also the best months to cruise to Alaska to soak in the rays of the Midnight Sun.

Best time to see the Northern Lights

The best chances to view the Northern Lights are during the long, dark, and clear months, either in early April or close to the fall equinox in late September. That said, though this is possible, it is not guaranteed on an Alaskan cruise. Where you are also matters a lot, the further north, the better.

Best time to get the 360-degree experience of northern lights:

Try to catch the northern lights between midnight and 4:00 AM when the auroras are most active. Summer months (May to August) are great for cruising but not ideal for seeing the Northern Lights because of the long daylight hours. Late September is a better time, with pleasant weather and darker skies.

Best time for Glacier Calving

The thunderous calving of the ice is a spectacular natural phenomenon to behold. This warning of climate change when the arctic blue ice plunges into the sea is during the warmer months of June, July and August at the site of active glaciers.

As temperatures begin to rise, glaciers start to calve more frequently. So, these warmer and drier months offer the best viewing experience. More particularly, if you are interested in watching more dramatic ice calving, August is the perfect time. With the increased ice movement, you will surely see the majestic, vibrant blue glaciers contrasting against the ocean.

Best time to cruise Alaska crowd-free

Spring, before the school breaks, is the best time to visit Alaska for shorter lines, peaceful meals, and a lot more elbow room. At this time you will be able to see the amazing sights of animals emerging from the mountains to graze on the verdant grass fields. Moreover, there will be fewer mosquitoes at this time of the year than in summer.

Here is the complete breakdown:

• May: If you love cooler temperatures with less crowd and some wildlife sightings.
• September: Cruise prices drop, and you can find better deals on accommodations and excursions. Plus, you will also experience the stunning fall foliage.

Best time to see wildlife

Alaska’s wildlife is legendary, as most of the species found here cannot be seen anywhere else on this planet. From brown bears scooping salmon to bald eagles flying overhead or a pod of orcas in the ocean, the best time to see these dramatic displays is from mid-July to mid-August.

From late May to mid-June, you can also birdwatch. These are the months when Migratory songbirds return. If you are interested in marine life animals, the mid-June to August window is for you. Humpback whales are most active during this period (particularly in June and July) when they are often seen bubble-net feeding. Orcas are also prevalent, especially from July to August.

Cruise Alaska in Shoulder Season for Cheaper Rates

If you want to get affordable rates, visit Alaska in shoulder season. Cruises during May and September are often 20–30% cheaper compared to peak summer months. Excursion prices and onboard deals are also more budget-friendly.

On the other hand, ports and attractions in shoulder seasons are less crowded. It means you can get a more relaxed experience of the journey.
