Alaska Baby!

The best time to cruise Alaska isn’t obvious—until you’re quietly sailing along its calm waters under a cloudless, late-spring sky. It was on one such day that someone on board spotted a whale breaching. And then again. And again. Within minutes it seemed everyone on board had gathered at the railings on deck to watch. The captain of the ship nimbly repositioned us, giving both the port and starboard sides prime viewing, at a safe and respectful distance from the animals. With binoculars, cameras, and phones at the ready, the passengers and crew aboard UnCruise Adventures’ 86-guest S.S. Legacy settled in for what turned out to be an hour-long private show by a juvenile humpback who had migrated from Hawaii to spend the summer in the nutrient-rich Alaskan waters.
We sailed roundtrip from Juneau, and while I’ve visited the capital city during the busy summer months, I found the restaurants, bars, and shops much less crowded, reliably filled with locals for the most part. On the water, we rarely passed any other ships or boats, aside from fishermen out for their catches.
According to Travel Alaska, cruising is the most popular way to explore the state, and Cruise Lines International Association Alaska reports that more than a million cruise passengers sail to and within Alaska each season.
But when is really the best time to sail Alaska? We’ve broken the seasons down for you, including the highlights of each, as well as the best cruise lines and cruise ships to consider so you can make your bucket list dreams come true.
April and May
If your schedule allows, not only does sailing Alaska in April and May afford the possibilities of glimpsing the Northern Lights and seeing wildlife emerge from their winter hibernation, it’s a more affordable and less crowded time to cruise, too. April and May are also the driest months in Alaska, so the chances of rain are slim.
Norwegian Cruise Line is among the lines that open the Alaska cruise season in April, when few other ships are sailing.
Smaller ships like those that comprise UnCruise Adventures’ and Alaska Dream Cruises’ fleets can maneuver closer to the coastline for better views of bears rambling along the beaches and on-land excursions without another soul around. Ask your travel advisor for current itineraries and fares.

June to August
Warmer temperatures, an average of 17 hours of daylight, and schools’ summer vacations all make Alaska a popular destination for cruising in June, July, and August. Expect crowded ports and more ships out on the water, but that’s not to say it’s not a good time to set sail: bears are still active, as are whales and native bird life.
Holland America Line, which has sailed in Alaska for decades, offers dozens of itineraries throughout June, July, and August. Family favorite Disney Cruise Line also sails Alaska over the summer.
September
Not only is school back in session in September, which means fewer crowds at ports, but the chances of seeing the Northern Lights return, especially if combining your cruise with a land tour that takes you further north into Alaska. Fall is also mating season for wildlife, so expect to see some friskiness.
Celebrity Cruises and Princess both sail Alaska in September, including cruise-tour options that pair time on land with a week at sea.
October
The Alaska cruise season winds down in October, with only a few ships setting sail. Just as in April and May, you’ll likely have the water to yourself, and even fewer people in the ports you call upon. Along with cooler weather, you’ll also find lower fares that will please your bank account.
Norwegian Cruise Line, which opens the season in April, is also among the last lines to sail the state each year.
