If you’re heading out in Chennai today, the live forecast above gives you the current conditions—plan for a warm, humid day typical of the city’s tropical climate. The northeast monsoon, active from October through December, brings heavy rain, so keep an umbrella handy if you’re visiting during those months.
What is the typical weather pattern in Chennai?
Chennai sits on the southeastern coast of India, giving it a hot, humid tropical climate year-round. Daytime highs usually hover between 30°C and 40°C, with the coolest months (December–February) still feeling balmy. The city receives most of its rain from the northeast monsoon, while the southwest monsoon brushes the west coast. Humidity stays high, often above 70%, making the heat feel more intense.

Does Chennai ever get cold?
Chennai rarely sees temperatures below 20°C. The coolest nights in January can dip to around 18°C, but that’s still mild compared to northern Indian winters. You won’t need heavy winter clothing.
How accurate are Chennai’s long-range forecasts?
Forecasts beyond seven days become less reliable due to the dynamic monsoon system. For the chennai weather forecast 30 days, use them as a general trend rather than a day-by-day plan. For short-term accuracy, check the weather in chennai 10 days outlook from the Indian Meteorological Department.
