Two continents, fourteen million people, and the call to prayer five times a day. The Bosphorus ferries are the heartbeat — take one at sunset, no agenda.

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.
