If Alaska is on your list, you’re probably wondering when to go. The cruise season runs from May to September, but each month offers a different kind of experience. Some are better for wildlife, others for fewer crowds, and some hit just the right balance of long days and mild weather.
Here’s a clear breakdown of what each month feels like on the water, and what you might see and do along the way.
Good for: Quieter travel, snow-covered landscapes, and early wildlife sightings
What to expect: Fewer people, fresh air, bears waking up, and whales starting to arrive
May is when the season begins. The air is cool and crisp, and the mountains are often still covered in snow. There’s a peacefulness to travelling this early, and it’s usually easier to find a good deal. Not everything is open yet, so some shore excursions may be limited, but if you like your travels a bit quieter, it’s a rewarding time to go.
Good for: Long daylight hours, stable weather, and active wildlife
What to expect: Humpback whales, seabirds nesting, and golden evenings
June is a favourite for many. The days stretch out, especially in the northern ports, and there’s a real sense of energy. Wildlife is active, the scenery is lush, and the cruise calendar is in full swing. There are more people on board, but it doesn’t feel overwhelming. This is a solid choice if you want the best mix of nature, daylight, and access.
Good for: Warm weather, family holidays, and full access to activities
What to expect: Busier ports, lively ships, and open trails
July is peak season. School holidays are in full flow, so you’ll see more families on board. All major sites and excursions are up and running, and the weather is usually at its most comfortable. It’s the most popular month, so prices go up and things book out early. If you’re cruising in July, it’s worth planning ahead.
Good for: Wildlife watching, salmon runs, and dramatic scenery
What to expect: Brown bears near rivers, salmon leaping, and changeable weather
August is a brilliant time to see wildlife, especially if you’re hoping to spot bears. The salmon runs are in full swing, which attracts all kinds of animals to the rivers. There’s a richness to the landscape this time of year, with light starting to shift and a hint of autumn in the air. Weather can be unpredictable, so pack layers and waterproofs just in case.
Good for: Peaceful travel, autumn colours, and better cruise fares
What to expect: Quieter ships, forests turning gold, and cooler afternoons
September marks the tail end of the season, and it has a completely different feel. The pace slows down, the crowds thin out, and the scenery turns golden. Cruise lines often offer better rates and bonuses for late-season sailings. It’s cooler, and daylight hours are shorter, but the trade-off is a calmer atmosphere both on and off the ship.
| Month | Best For | Things to Consider |
|---|---|---|
| May | Crisp scenery, peace and quiet | Some activities may not be running yet |
| June | Long days, wildlife, mild conditions | Getting busier as the season builds |
| July | Families, open trails, warmer weather | Peak crowds and higher prices |
| August | Salmon, bears, active landscapes | Weather can shift quickly |
| September | Tranquillity, colours, savings | Cooler weather and fewer daylight hours |
There’s no single “best” time to cruise Alaska. It really depends on what matters most to you. Some people want to tick off as much wildlife as possible, while others are chasing quiet fjords and fewer fellow travellers.
If you’re eyeing a specific place like Glacier Bay, it’s also worth checking availability early, as access is limited and permits go quickly.
