Pondicherry is hot and humid all year round with temperatures ranging between 26°C and 38°C. March, April, May and June are the hottest months with temperatures touching 40° C; humidity levels remain high despite hot winds blowing seawards from the mainland.
Rains arrive soon after; July, August and September are pleasant mainly because the heat and humidity are relieved by the showers of the southwest monsoons. The arrival of the northeast monsoon coincides with the winter months of November, December, January and February - this the best season to visit Pondicherry with day temperatures around 30° C and pleasant cool evenings
