Summer weather in Southeast Alaska is variable, and it is wise to prepare for rain or shine. Annual precipitation ranges from 30" around Skagway up to about 160" in the Ketchikan area. About half of the precipitation falls from September through December.
Storms usually blow out of the southeast. Winds of 30 knots are common, and storm winds can be 50 knots or more. The driest months tend to be June through August, although May in the last couple of years has been fantastically fair. August can be foggy. Any summer day can be sunny and hot.
Northerly winds usually bring fair weather, but still can send 20 knots of wind, usually in the afternoon.
The best idea is to come prepared for an adventure that might include rain, sun, wind or fog - or all of the above. Dressing in layers allows you to adjust to current conditions. Kayakers, of course, have to protect themselves against the very cold waters, whatever the air temperature.
There may be days when the weather keeps everyone close to, if not on board, the mothership. Such days are good for photographing wildlife and weather, writing postcards, keeping company with a good book and hot tea or, if you purchased a license and put on one of our big raincoats, dropping a hook or a trap for the catch of the day.
Take it from these guys, the weather is part of the fun in Southeast Alaska!
