The Southeast has Alaska’s mildest climate. Greatly affected by warm ocean currents, the region has warm summer temperatures averaging 69°F (20°C), with an occasional heat wave that sends temperatures to 80°F (27°C). Winters are also relatively mild, and subzero days are rare. Residents, who have learned to live with an annual rainfall of 60in to 200in, call the frequent rain ‘liquid sunshine.’ The heavy precipitation creates the dense, lush rainforests and numerous waterfalls most travelers come to cherish.
