About Kolkata weather
Kolkata sits within West Bengal's Gangetic delta region, humid for most of the year and prone to Bay of Bengal cyclone activity near the coast, about 151 km south-east of Durgapur. Conditions turn hot with a hot, humid pre-monsoon season (April–June) with highs often above 35°C and frequent nor'wester thunderstorms (kalbaishakhi). Then comes the south-west monsoon (June–September), a heavy and reliable rainy season across the state. By December, expect a short, mild winter (December–January) — one of the more pleasant stretches of the year.
