Wondering when the best time to cruise Alaska is? This guide will help you decide the ideal time to go—whether you’re interested in warmer weather, wildlife spotting, or witnessing the majestic Northern Lights.
The best time to cruise to Alaska comes down to personal preference, and experiences are valued most. The "best time" could be different for a solo cruise traveler who dreams of photographing bears than it is for a parent who wants a family-friendly vacation in the great outdoors.
Read on to discover the best time of year to cruise to Alaska, based on your personal preferences and the breathtaking experiences you want to check off your bucket list.
The Alaska cruise season runs from May to September, with a few sailings in late April and early October. While every month offers something unique, your ideal cruise timing depends on your interests—whether it’s wildlife viewing, the best deals, warmer weather, or less crowded attractions.
| Month | Highlights |
|---|---|
| April | Early season sailings with lower fares; chances of spotting the Northern Lights |
| May | Less crowded spaces, wildflowers blooming, active wildlife, baby moose sightings |
| June | Long daylight hours, warmer weather begins, eagle fledglings visible |
| July | Warmest month, peak whale watching, glacier calving in full force |
| August | Salmon runs = bear viewing; lush landscapes and festivals |
| September | Fall colors, quieter ports, late-season deals, possible Northern Lights sightings |
| October | Select sailings with dramatic autumn scenery and peaceful ports |
Spring marks the beginning of Alaska’s cruise season, offering fewer crowds, lower fares, and breathtaking views of snow-capped mountains. May brings cooler temperatures and clearer skies, with active wildlife like moose calves and bears emerging from hibernation. It’s also a great time for birdwatching and photography.
By June, the days are longer and the landscape bursts into bloom. Whale sightings become more common as humpbacks return, and eagle fledglings begin to appear in their nests. With warmer weather and more daylight for excursions, June is a favorite for travelers who want to experience Alaska’s wild beauty at its freshest.

Tell a sun-worshiper that you’re taking an Alaska cruise and they’ll raise an eyebrow. Yes, it’s chilly. Yes, even in summer. On average in July, Alaska boasts high temps in the mid-60s, but occasionally climbs into the 70s and 80s. It’s also misty and drizzly. However, if you prepare for Alaska’s chill and damp weather, no matter what time of year you visit, you’ll have a great time. Bring a jacket, gloves, and scarves, along with waterproof gear, and sunscreen. Read how to pack for an Alaska cruise to stay comfortable in changing weather.
The most temperate Alaska weather is in July, then June and August when it’s warmer (though again, not near tropical) and drier. When it comes to May vs. September, May is slightly cooler, but gets significantly less rainfall. Temps can vary greatly depending on where you are in the state.
| Month | Low | High | Precipitation |
|---|---|---|---|
| May | 41°F | 57°F | 3.4 inches |
| June | 47°F | 62°F | 3.2 inches |
| July | 50°F | 64°F | 4.6 inches |
| August | 49°F | 63°F | 5.7 inches |

Peak summer— think late June through August—offers the longest days, widest range of kid-friendly excursions, and warmest weather for easy layering and outdoor adventure. Earlier in June tends to land slightly thinner crowds with nearly the same daylight magic, while late August brings salmon runs that make wildlife viewing an unforgettable memory. Remember! Book popular adventures early, bring backups of essentials, and pack waterproof layers so little explorers stay comfortable if mist rolls in.
Shoulder season is the savvy traveler’s best-kept secret: May and September often bring lower fares, more stateroom choices, and quieter port traffic without losing the grandeur. May tends to be drier and crisp, with fresh blooms and active wildlife; while September trades softer prices for fall colors and a better chance, if you’re lucky, at Northern Lights. For even more savings, aim for midweek departures, watch for last-minute deals, and book airfare through Flight Ease® to keep costs friendly.
The best time to experience Alaska’s midnight sun is from mid-May through mid-July, when daylight stretches late into the night. This natural phenomenon gives visitors more time to explore—perfect for hiking, sightseeing, and making the most of Alaska shore excursions.
Winter, when nights are long, dark, and clear, is the best time to see the Northern Lights in Alaska. That said, it is possible but not guaranteed to see them on an Alaska cruise. An Alaska cruise in early April or late September, close to the fall equinox (September 21), will increase your chances. Where you are can make all the difference and the farther north, the better.
The best time to witness glacier calving in Alaska is during the warmest months—June, July, and August—when active glaciers are most likely to shed massive chunks of ice into the sea. It’s an unforgettable experience, combining dramatic sights and sounds as brilliant blue ice crashes into the water below.
Spring, before school lets out, is the best time to cruise to Alaska with extra elbow room, shorter lines, and peaceful meals. You’ll still see amazing sights, like Dall sheep and other creatures who emerge from the mountains to graze verdant fields. Bonus: there are less mosquitoes in spring than summer.
Late spring through midsummer delivers long, golden evenings, snow-capped backdrops, and lively wildlife—perfect for wide landscapes and action shots. July and August add glacier calving drama and peak whale activity, while September paints the hillsides in crimson and gold with softer, moodier light. Bring a fast lens for low light, a polarizer for glare on water and ice, and waterproof gear so inspiration never waits on the weather. If capturing unique animals is your ultimate goal, keep reading on for the best times to spot the iconic wildlife of Alaska.
Bald eagles soaring overhead. Alaskan brown bears scooping up salmon from a rushing waterfall. A pod of orcas spyhopping in the ocean. Nature is in full bloom during cruise season in Alaska, but what you’ll see depends on the time of year and location.
At all times during cruise season, you’ll meet some of Alaska’s wild residents: eagles, whales, dolphins, and bears. Want to get up close and personal? The best and safest way to experience Alaska wildlife is through one of our guided Alaska shore excursions.
Here are some of Alaska’s most fascinating creatures and the best times of year to see them:
About 30,000 eagles call the Great Land home, and they’re more abundant in Alaska than anywhere else in the United States. There’s a good chance you’ll see eagles perched high near the shoreline, in town scavenging garbage dumps, or even feasting off a salmon run. Bald eagles hatch and rear young in April and you can see their mottled fledglings from May through June. Bring binoculars; eagles like to nest high.
Witnessing bears catch (or try to catch) slippery salmon from a river is one of the most incredible Alaska experiences you can have. The best time to view this dramatic display is mid-July to mid-August, though you can take wildlife excursions to bear hangouts at any time during cruise season.
Don’t underestimate fish. Salmon have a fascinating, beautiful life cycle well worth viewing. When they’re fully mature, millions take a harrowing upstream journey from the ocean to the rivers where they were born. The few who make it spawn and die here. Salmon runs in Alaska start in early May and continue until September, with different species of salmon running at different times of year.
Fuzzy baby moose, called calves, are as cute as it gets. Late May and early June are the best possible times to view a momma moose and her calves in Alaska. Moose can be dangerous, especially a threatened mom. If you do see these majestic creatures hulking around, stay far back (at least 50 feet) and never disturb a lone calf, as mom is somewhere nearby.
Alaska has humpback whales, gray whales, killer whales, and a small population of belugas. Though it’s species-dependent, the best time to go whale watching in Alaska is in high summer, when the days are long and the feeding is plentiful. And it all depends on what species you intend to see — humpbacks are in the area year-round, while others like gray whales migrate to Alaska in summer.
Alaska doesn’t always promise perfect weather — but it will always reward good planning with unforgettable moments. Pick a season for the experiences that matter most, then pack smart and book early so daylight, wildlife, and glaciers do the heavy lifting. Here are our top insider tips for being prepared for your visit:

The best month varies from traveler to traveler based on preferences—June and July deliver long daylight, warmer temps, and abundant wildlife for classic summer adventures, while August layers in peak salmon runs for bear viewing. For crisper air, quieter attractions, and better value, May offers blooming landscapes and active spring wildlife.
Shoulder season, which includes both May and September, typically brings the best fares, more stateroom choices, and quieter ports without sacrificing enjoyment. May tends to be cooler and drier, while September adds fall color, making both months value-rich times of the year.
