About Sirkazhi weather
Sirkazhi sits within 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, about 123 km north-east of Tiruchirappalli. Conditions turn hot with a hot summer (April–June) with highs often in the high 30s°C. After that, Sirkazhi sees 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. By December, expect a mild, short winter (December–January) with little temperature drop near the coast.
