Kolkata's Climate
Kolkata sits on the Ganges delta and has a tropical wet-and-dry monsoon climate, hot and humid for much of the year. Pre-monsoon summer from March to May is sweltering, often topping 38–40°C with oppressive humidity, before the southwest monsoon delivers heavy downpours from June through September, sometimes intensified by Bay of Bengal cyclones. Winter from December to February is pleasantly dry and cool, roughly 12–27°C, and is the most comfortable time of year.
