This coastal district, stretching down to the Sundarbans, is at the mercy of the Bay of Bengal — the slightest low pressure brings heavy rain, and tidal water floods low-lying areas. During cyclone season (May–November), the forecast here matters more than anywhere else.
The storm-surge risk is highest in the low-lying islands of Kakdwip, Namkhana, Sagar Island and the Sundarbans — follow official instructions and move to relief shelters when a storm is forecast.
October to March — humidity is lower and storms are less likely. Summer is oppressively muggy and boat travel is risky during the monsoon.
Usually from mid-June to mid-September — this window brings the lion's share of the annual rainfall.
