Alaska Cruise Weather in May

After spending the winter in warmer climates, humpback whales migrate north and break the waters of the Inside Passage, marking the dawn of Alaska’s most vivacious season. Hundreds of king salmon grace the majestic waters of the Pacific while freckled lynx bask in the early summer sun. Thanks to the modest daytime temperatures and refreshing evening climates, May is peak season for many of Alaska’s most cherished wildlife. Weather typically ranges from the 30s to a high of around 55 degrees Fahrenheit. May itineraries invite guests to pack sweaters and jackets for easy layering.

Feel the warm embrace of the summer sun throughout June when the Land of the Midnight Sun experiences the height of its daylight. With over 18 hours of golden sun each day, Alaska landscapes kiss the snowy surfaces goodbye and welcome the lush green meadows that bear the fruits of winter’s labor. With newly dried surfaces, hiking expeditions commence. As you venture into the depths of Alaska’s wilderness, reach new heights where you can enjoy unparalleled views of staggering glaciers and roaming hillside wildlife. With lows in the upper 40s and highs in the mid-60s, allow the revitalizing, crisp breeze to tickle your neck as you rejoice in the unforgettable climb.

In Icy Strait Point, find regal brown grizzly bears roaming through streams in search of fresh salmon. Or, look for lively humpback whales making a splash off the coast of Juneau. As you embark on your summer adventure, bring light jackets for hiking through shady regions as well as plenty of sunscreen for basking in 18 hours of glorious sunlight each day this month.

Alaska Cruise Weather in August

Cast your line into the marvels of an Alaska summer by cruising in August. As you sail into each port of call, delight your taste buds in the delicacies of Alaska’s waters. Donning subtle notes of the sea, the silver salmon is one of the most sought-after fish and just so happens to be most fruitful this time of year. Whether or not fishing is your forte, be sure to pack water-resistant apparel for every splash and sprinkle that may arise from kayaking down crystalline fjords and hiking through misty rainforests. With lows in the upper 40s and highs of around 60, you’ll feel refreshed and eager to explore the captivating wonders of Alaska.

Alaska Cruise Weather in September

As September begins, the sun dips below the horizon signifying the inauguration of fall. The lush green forests transition into vibrant hues of gold and saffron while the mountaintops become freckled in snowfall. Daylight quietly recedes and the growing twilight perfectly contrasts the luminous green lights of the Aurora Borealis. The enchanting colors invite you to marvel at the miracles of Mother Nature that so often act as the inspiration for treasured postcards. With only 12 hours of sunlight, temperatures range from around 43 degrees to the mid-50s. These new, cooler climates encourage Alaska’s famed wildlife to begin preparing for hibernation. Gaze at the water’s surface as thousands of bald eagles congregate to enjoy the final salmon of the season.

Best Month to Take an Alaska Cruise

What is the best weather for an Alaska cruise? Temperatures can vary anywhere between 30 to 80 degrees throughout the summer travel months – inviting guests to layer on the sweaters and windbreakers as weather can be unpredictable. So, the best month to travel to the Great Land depends on what you want to do. For the fishing aficionado, consider May when king salmon reach their greatest appearance.
