Alaska.com

Southeast Alaska is a land of rain forests, salmon streams and glaciers, all made possible by the wealth of precipitation driven in off the Gulf of Alaska.

The Inside Passage has the highest annual precipitation averages in the state as well as the highest average temperatures. For anglers, kayakers, hikers and cruise ship passengers, jackets and rain gear are almost always appropriate. Rubber boots are worn so frequently that they're known as "Alaska tennis shoes" and "Sitka slippers."

Rainy towns

Ketchikan averages 150 inches of precipitation a year, almost 3 times Juneau's total and 10 times what Anchorage gets. Yakutat, near enormous Malaspina Glacier, averages 145 inches of precipitation, including the meltwater from 193 inches of snow. Year to year, the wettest place in the state is Little Port Walter, which averages 220 inches.

Juneau gets more than 18 hours of sunlight at the summer solstice in June but less than 6.5 hours at the winter solstice. Ketchikan, 250 miles south of Juneau, gets less (17.5 hours) at the summer solstice but more (7 hours) in December.

Here are monthly averages -- high temperature, low temperature, precipitation (inches of rain and melted snow), snowfall and snow depth for Southeast locations: Angoon, Annette, Glacier Bay, Gustavus, Haines, Hollis, Juneau, Ketchikan, Petersburg, Sitka, Skagway, Wrangell and Yakutat.
