Quick answer
The best time to visit Pondicherry is from December to February, when the weather is at its most pleasant. October to December brings the north-east monsoon, with the heaviest rain of the year, and April to June is hot and humid.
Pondicherry has a warm, humid coastal climate all year, so the question is less "when is it warm" and more "when is it comfortable". The town follows the pattern of the Tamil Nadu coast: its main rains come with the north-east monsoon at the end of the year, not in the summer months as in much of India.
Winter: December to February
This is the most comfortable time of year. Days are warm rather than hot, evenings are pleasant with a breeze off the sea, and the sky is often clear once the monsoon has passed. It is also the busiest season, with Christmas and New Year bringing many visitors. Book stays, restaurants and cruises ahead, especially around the end of December.
Spring: March
March is still pleasant in the mornings and evenings, with the heat building through the month. It is a good time for a quieter trip after the winter crowds.
Summer: April to June
Summer is hot and humid, with the hottest weeks usually in May and June. Visitors still come, especially for weekends by the sea, but plan the day around the heat: be out early in the morning and in the evening, and rest in the middle of the day. An evening on the sea is one of the most comfortable ways to spend a summer night.
July to September
The south-west monsoon brings rain to much of India in these months, but Pondicherry stays fairly dry, with some showers. It is warm and humid, quieter than the winter season, and a reasonable time to visit.
The north-east monsoon: October to December
From October to December, the north-east monsoon brings Pondicherry most of its rain for the year, sometimes in heavy spells, and the Bay of Bengal can see cyclones in this period. It is still possible to visit, and the town is green and fresh, but keep plans flexible: outdoor trips and boat rides depend on the weather. Check the forecast before you travel and follow local advice.
Weather and boat trips
Boats and cruises sail only when it is safe. In the monsoon months and on windy days, a sailing may be cancelled at short notice. If you book a cruise, keep your phone on for messages from the operator and plan a backup for the afternoon.
