Give Reasons as to Why: The Tamil Nadu Coast Receives Winter Rainfall

By Shivank Goel|Updated : September 5th, 2022

According to the Koppen climate classification, a significant part of Tamil Nadu tends to have a tropical savanna climate. In contrast, a smaller portion of the state tends to have a humid subtropical climate. The state's climatic conditions range from dry and sub-humid to semi-arid. This article will explain why the Tamil Nadu coast receives winter rainfall.

Tamil Nadu Coast Receives Winter Rainfall

The northeast monsoon, which blows from land to sea, brings rain to the Tamil Nadu coast during the winter. In the country's north, they do not affect rainfall. However, as they pass the Bay of Bengal, they take up moisture and bring rain to parts of southeast India, particularly the coast of Tamil Nadu. The reasons why the Tamil Nadu coast receives winter rainfall are as follows:

  • The monsoon season lasts between 100 and 120 days, from early June until mid-September. While most of the country receives rain from June to September, other regions, like Tamil Nadu, receive the most rainfall in October and November.
  • The Northeast trade winds dominate the nation's weather during the winter.
  • As the winds blow from land to sea, it is a dry season across most of the nation.
  • Rainfall occurs when winds blow from the sea to the land and gather moisture from the ocean.
  • The east coast experiences rain because of its physical location, where the northeast trade winds blow from the sea to the land. As a result, Tamil Nadu's coast experiences winter rains.
