Bangladesh is among the most climate-vulnerable countries in the world. Every monsoon, Sylhet, Sunamganj and the char lands of the Brahmaputra are devastated by flash floods. Every pre-monsoon summer brings punishing heatwaves, with the 2024 heatwave pushing temperatures to a record 43.8°C, more than 16 degrees above the annual average, forcing nationwide school closures that disrupted education for 33 million children. As climate extremes are on the rise each year, a reliable weather alert app is no longer a luxury — it’s a safety necessity.
1. BMD Weather App – The Official Government Source Platform: Android | Price: Free
The BMD Weather App is the first thing every Bangladeshi needs for alerts coming right from Bangladesh’s national meteorological authority. Developed by the Bangladesh Meteorological Department, the app provides weather observation and forecasts for all Bangladesh locations, including divisional and station level data, temperatures, humidity and seven-day rainfall history.
The key benefit is that it links directly with official hazard warnings. Bangladesh Meteorological Department (BMD) issues official warnings for different categories, including Heavy Rainfall, Kalbaishakhi (Nor’wester) warnings, Heat Wave, Cold Wave, Marine, Inland Riverport, and Cyclone warnings. This is the only source of pre-cyclone signals for coastal residents in Barguna, Patuakhali or Cox’s Bazar.
2. AccuWeather — Best for Hyperlocal Heatwave & Storm Tracking Platform: Android & iOS | Price: Free (Premium Plus available)
AccuWeather provides detailed, hyperlocal forecasting for any address in Bangladesh, with hourly and extended forecasts. Its MinuteCast feature predicts precipitation minute-by-minute – invaluable during the unpredictable Kalbaishakhi season. The latest version of the app features new lightning alerts powered by AccuWeather’s Lightning Network, additional map layers for Air Quality Index, Wind Flow and a more refined radar display to help keep users safer from life-threatening weather.
AccuWeather’s RealFeel® temperature includes humidity, wind and sun angle for tracking heatwave — far more practical than a raw temperature reading during a humid Rajshahi summer.
3. Bangladesh Weather App – Best for Flood Station Monitoring Platform: Android Price: Free
This Bangladesh-specific app combines daily forecasting with real-time flood risk data. It offers a 10-day forecast for major cities, and flood alerts on an interactive national map, with a dedicated layer showing flood warning stations across river basin areas. This flood station map is an invaluable monsoon season tool for farmers and residents of Haor districts like Sunamganj and Kishoreganj.
The Bottom Line
Use BMD for official government signals, AccuWeather for accurate heatwave and storm tracking, and the Bangladesh Weather App for real-time flood station monitoring. Together, the three apps provide the most complete weather safety net in any Bangladeshi smartphone in 2026.
Summary
Bangladesh faces intensifying flash floods, cyclones, and heatwaves every year. These 3 apps — BMD Weather App, AccuWeather, and Bangladesh Weather App — deliver real-time alerts to help you stay safe in 2026.
