About Juneau
Juneau, officially the City and Borough of Juneau, is the capital of the U.S. state of Alaska, located along the Gastineau Channel in Southeast Alaska.

How we ranked these
Each month is scored on temperature comfort (18–27°C avg high is the sweet spot), rainfall (more rain days = lower score), snow days, and peak hazard seasons (hurricanes, monsoons, etc.). Green-tier months are within ideal range with no major issues. Yellow are workable but with trade-offs. Red has at least one significant problem — extreme heat or cold, heavy rain, or peak storm season.
