Glacier Bay National Park & Preserve - Climate

Bartlett Cove receives about 70 inches of precipitation annually. You may find yourself thinking it’s all coming down during your visit! April, May and June are usually the driest months of the year. September and October tend to be the wettest. All this moisture helps to create the lush temperate rainforests of the lower bay.

Keep in mind, these are weather conditions at sea level. Up in the mountains, conditions are more severe with colder temperatures and more precipitation that takes the form of snow. It’s all that snow falling year after year that goes into creating the magnificent glaciers we love to see.
