When is the best time to visit Tamil Nadu
November to March is the season: warm, dry and festival-rich, with the harvest festival of Pongal in January among the highlights. April to June is intensely hot and best avoided for a temple trail. One thing catches many visitors out: unlike most of India, Tamil Nadu's coast draws its main rain from the northeast monsoon between roughly October and December, so expect some showers early in the season, especially around Chennai.
Season by season
- Nov–Mar: the best season, warm and dry with festivals including Pongal in January.
- Apr–Jun: the hot season, intensely hot and best avoided for a temple trail.
- Oct–Dec: the northeast monsoon, bringing showers especially around Chennai.
- Month by month: plan in more detail against your own dates.
The northeast monsoon, explained
Unlike most of India, Tamil Nadu's coast draws its main rain from the northeast monsoon between roughly October and December, not the summer monsoon that soaks the rest of the country. October sits inside the travel season and is also its wettest stretch, so expect some showers early on, especially around Chennai, rather than ruling the month out.
