About Besant Nagar weather
Besant Nagar, in Tamil Nadu's eastern coastal plain along the Bay of Bengal, which — unlike most of India — gets its main rains from the retreating north-east monsoon, is positioned about 9 km south of Chennai. The warmer months mean a hot summer (April–June) with highs often in the high 30s°C. The rainy season is the north-east monsoon (October–December) — Tamil Nadu's principal rainy season — with a weaker south-west monsoon contribution (June–September) mainly over the western interior. Finally, there's a mild, short winter (December–January) with little temperature drop near the coast.
