Before the monsoon arrives, short but violent Kalbaishakhi storms can build up in the afternoon or evening. Cyclone risk from the Bay of Bengal is highest around April–May and again in October–November.

Tips for planning your day in Sunamganj
- Check the hourly rain chance, not just the daily figure: a 60% day can still have long dry spells.
- When humidity is high, the heat feels stronger than the thermometer suggests. Early morning and late afternoon are usually the most comfortable times to be outside.
- Around midday, check the UV index: at 6 and above, a hat, sunglasses or sunscreen help.
- During storm or flood season, follow official updates from the Bangladesh Meteorological Department (BMD) and the Flood Forecasting and Warning Centre (FFWC), linked in the report.
