How extreme does Kolkata's weather get?

The hottest, coldest, wettest and snowiest days Kolkata has recorded — the outer limits of what its weather can do, and how far they sit beyond a normal day.

Based on 10 years of daily weather observations (2015–present), from the Behala station 10 km away. Updated through August 2025 — an all-time extreme only changes when a more extreme day actually occurs, so some dates are old. That is normal, not stale data.

The four kinds of extreme

The hottest, coldest, wettest and snowiest single days Kolkata has recorded — each shown against what a normal day that time of year looks like.

In plain terms

Across the record, Kolkata has reached as high as 106°F and as low as 49°F. A single day has delivered over 7 inches of rain. Those are the outer edges worth knowing if you are moving here, planning a trip, or thinking about a house.

Methodology & sources

Temperature & precipitation — 1991–2020 normals computed from 30 years of daily observations at Netaji Subhash Chandra Bose Intl, a weather station, about 13 km from the city centre. The underlying daily records come from NOAA's global station network.
