Crowds is a score out of 100 where higher is quieter. It counts public-holiday clusters in JP as well as at Kolkata, 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.

How busy it gets

Busiest in March and May.

The year in Kolkata

Expect severe rainfall during the monsoon season, especially from June to September. Temperatures can also be extremely high before the monsoon. Observations from the ERA5 data are consistent with this information.

Busiest	mid Oct to mid Nov — Festivals and pleasant weather attract many tourists.
Quieter, still good	early Dec to late Dec — Weather is still pleasant post-festivals, but tourist traffic declines. early Feb to late Mar — Mild temperatures and lower humidity make this a good time to visit. early Oct to mid Oct — Weather is pleasant before the festival rush.
Wet or stormy	early Jun to late Sep — monsoon, severe
Worth timing for	Durga Puja, October, lunar — Prices surge and some infrastructure may close.
Watch out for	extreme heat; haze

Written by a language model from the climate figures above. 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.
