If you’re starting your Alaska cruise planning, here’s the first thing to know: Alaska’s cruise season is short. Unlike Caribbean cruises that sail year-round, Alaska’s season typically runs from May through September, with limited sailings in late April and early October.
Even within that narrow window, the month you choose can have an impact on your Alaska cruise experience. From weather and wildlife to crowds, pricing, and excursions, timing matters.
Here’s what we tell our clients when they’re planning an Alaska cruise.
May & Early June: Quieter, Cooler, and Budget-Friendly
Best for: Fewer crowds, spring blooms, lower prices
Wildlife: Early bear sightings begin; bald eagles are active
National Parks: Denali begins opening mid-May (note: you will need a cruisetour or your own, custom inland adventure to experience this…which we also help plan!); Glacier Bay sailings resume late May (ice-dependent)
Expect: Temps in the 40s–60s, snow-capped mountains, fewer families
If you’re looking for early summer Alaska cruise deals, May and early June offer great value and fewer people. This is a smart time for budget-conscious travelers and those who want to beat the crowds.
Mid-June to Mid-August: Peak Season = Peak Everything
Best for: Warmest weather (60°F+), 15+ hours of daylight, full range of excursions
Wildlife: Prime time for whale watching, bear viewing, birding, and salmon fishing
National Parks: Glacier Bay and Denali are fully open
Expect: Higher prices, more families and kids, excursions booking up fast
This is the heart of Alaska cruise season, and everything’s in full swing. If you’re planning your cruise around weather, wildlife, or activities, this is the most popular time to go. But book early because space goes quickly (seriously… like 12-18 months in advance).
Late August to September: Fall Colors, Great Deals & Possibly the Northern Lights
Best for: Crisp air, beautiful foliage, fewer crowds, shoulder-season savings
Wildlife: Bald eagles and bears still visible; some late whale sightings
Northern Lights: Late September offers your best chance to catch the aurora during cruise season (and your chances are even better if you travel inland on a cruisetour to Denali or Fairbanks)
National Parks: Glacier Bay and Denali are both still accessible
Expect: More rain, cooler temps (40s–50s), More adults than children
Fall cruises to Alaska can be a hidden gem. With the possibility of the Northern Lights in late September, lower fares, and T-shirts on sale, this is a great time for flexible travelers who don’t mind cooler weather.
Late April & Early October: Rock-Bottom Prices and Ultra-Low Crowds
Best for: Lowest prices, quietest sailings
Wildlife: Bald eagles, with occasional bear sightings before hibernation
National Parks: Mostly inaccessible; some local businesses start closing for the season
Expect: Itinerary changes due to weather, chilly temps, big discounts on souvenirs
Only a few cruise lines sail this early or this late in the season, but if you’re very flexible and want the best price, this could be your moment.
So… When Is the Best Time to Take an Alaska Cruise?
It depends on what you want:
- Warm weather & long days? July
- Fewer people & better prices? May or September
- Wildlife viewing? June through August
- Fall colors or Northern Lights? September
There’s no one-size-fits-all answer, but there is a right time for you.
