There are no extreme variations in temperature in Chennai and the two main seasons are summer and monsoon. During the summer months (March to September) mean temperature hovers around 33 °C but it frequently soars to the mid and high 30’s. May and June are the hottest months and is definitely not the time to visit Chennai as mercury levels can exceed 40 °C on certain days.

Monsoon starts in October and ends by mid-December. The city gets some heavy downpours during this period and records an average annual rainfall of around 1300 mm. Occasionally depressions in the Bay of Bengal also bring heavy rain and thundershowers to Chennai.
January and February are the best months to visit Chennai when average daily temperature is around 24 °C. Even at its coldest, temperature rarely falls below 18 °C in the city.
