By Dr. Dave Siefkes, Travel Expert

If you’ve ever dreamed of sailing past towering glaciers, watching humpback whales breach against a backdrop of misty fjords, or exploring rugged wilderness where bald eagles soar overhead… then an Alaska cruise should be at the very top of your travel list. Travel Agents have helped countless travelers plan unforgettable Alaskan adventures, we know how exciting, and sometimes overwhelming, it can be when you’re just getting started.

Here’s your one-stop guide to planning your first Alaska cruise, covering the best times to go, when and where to see the whales, must-see sights, what to expect from the weather, and which cruise lines do it best.

When’s the Best Time to Cruise Alaska?
The Alaska cruise season runs May through September, but each month offers a unique experience:

May & early June: Quieter ports, fewer crowds, springtime blooms. Some glaciers are especially active early in the season with ice calving.

Mid-June through August: Peak season… warmest temperatures (mid-50s to mid-70s), longest daylight hours, and best wildlife spotting.

September: Cooler temperatures return, but you can catch fall colors, and it’s a great time for deals on late-season cruises.


When to See Whales in Alaska
For many travelers, whale watching is the highlight of an Alaska cruise… and Alaska doesn’t disappoint.

Here’s what to know:
Humpback whales: The stars of Alaska’s Inside Passage, humpbacks are best spotted June through August when they migrate north to feed.

Orcas (killer whales): Can be seen anytime during the cruise season, but sightings peak May to early June and again late August into September.

Gray whales: Early-season travelers in April-May (on repositioning cruises or land tours) might spot gray whales on their migration.


Best Times for Glacier Viewing
Alaska’s glaciers are a true spectacle… watching massive chunks of ice calve into the sea is unforgettable.

Glaciers are active all season, but early summer (May-June) can bring dramatic calving events. Popular glacier highlights include Hubbard Glacier, Glacier Bay National Park, and Tracy Arm Fjord, all accessible by cruise ship.

What About the Weather?
Alaska’s coastal weather can be unpredictable… pack layers! Here’s what to expect: May–June: Generally drier, average highs 50-60°F. July–August: Warmest, average highs 60-70°F, but also the rainiest months. September: Cooler, average highs 50-60°F, but fall colors begin to appear.
