Glacier Bay in April: what the park service says

April opens the driest stretch of Glacier Bay's year: the park says April, May and June are usually the driest months. That is relative, since Bartlett Cove gets about 70 inches of precipitation a year, so good rain gear still matters. Higher in the mountains, colder temperatures mean the precipitation falls as snow, and hypothermia is a risk in every season.
