Istanbul from Kolkata
5,877 km, about 8h 05m in the air. Every month scored for the weather at Istanbul and for the holidays that crowd it out at both ends.
Affiliate links: we may earn a commission if you book through one, at no extra cost to you. It changes nothing above — the scores are computed from climate and fare data before any link is built.
Free, on Telegram. One tap — CCU is already chosen. We write
when a fare is genuinely below what that route normally costs, and
/stop ends it.
Public holidays at Kolkata move this destination's year too little to make it a different answer, so the Istanbul page is the one of record. This one is kept for the distance and the flight it implies.
No fare history on CCU–IST yet, so this ranking is climate and crowds only. The price column fills in as the scanner collects.

Crowds is a score out of 100 where higher is quieter. It counts public-holiday clusters in IN as well as at Istanbul, which is why this table differs from the same one read from another country. A busy month is a crowded one, not a bad one — usually it is crowded because the weather is good. Crowds alone never make a month “avoid”: that is reserved for weather worth skipping.
The year in Istanbul
Istanbul's climate is mild in winter compared to many places, making it a year-round destination. However, precipitation can increase outside the summer months.

mid Sep to late Oct — Temperate weather with decreasing crowds after summer high season.
early Nov to late Nov — The weather is still relatively mild and the crowds are fewer.
early Feb to late Mar — Cooler temperatures and fewer tourists provide better value.

This section was written by a language model from the climate figures above, and nobody has checked it. The month-by-month table is measured — ten years of ERA5 readings and published holiday calendars — and where the two disagree, the table is the one to believe. The busiest and quieter periods here also count toward the crowd score, which is 20% of the ranking.
