Answer: Tamil Nadu coast receives winter rainfall from Northeastern trade winds.
Between 100 to 120 days during the monsoon season, some places or topographic points like Tamil Nadu receive a large part of the rainfall during October and November from early June to mid-September. Still, on the other hand, many country regions receive rainfall from June to September.
When the wind flows from the sea to land, it takes up moisture from the sea and brings forth the rainfall in the country’s regions.
Due to the geographic location, the East Coast perceives the rainfall as the northeastern trade winds flow from the sea to land in this region.
