Weather by month
Juneau
Alaska
A rainforest capital with no road out — the weather comes off the water, the mountains hold it there, and the clear days feel earned.
The best time to come
May and June are the driest, brightest weeks Juneau gets, with the glacier and the whales both easy to reach and the cruise season not yet at full throttle. July is warmer but noticeably wetter, and September is spectacular if you like your rain committed.
