Climate of India Overview

It occurs due to the differential heating of land and sea, leading to changes in air pressure which drive the winds.

The concentrated rainfall occurs during the southwest monsoon season, which brings heavy rain from June to September.

The Tamil Nadu coast receives winter rainfall primarily from the northeast monsoon winds.
