Tamil Nadu can be visited year-round, although by far the most popular time is between December and March, when the skies are mostly blue and the weather not as hot as it becomes from April to June, especially on the inland plains. Coastal areas, however, only ever vary a few degrees either side of 30°C but humidity levels are consistently high from April through September.

The main summer monsoon largely misses Tamil Nadu but the state does receive plenty of precipitation during the northeast monsoon season from October to early December, when violent cyclones can be a threat, sometimes causing floods and wreaking havoc with transport links.

During the hotter months, the hill stations of the Western Ghats provide welcome respite from the heat but they can be pretty chilly, at least at night, in the winter. The Christmas and New Year period gets busy and prices are higher then and for local festivals, of which the state has many.
