In the Asansol–Durgapur coal-industrial belt, summer is the most oppressive in the state, and air pollution runs higher than any other plains district. Winter-morning smog drags the AQI down further, so watching the AQI in Durgapur–Asansol is essential.
Coal mines, thermal power plants, lime and steel factories, and road dust keep PM10/PM2.5 levels elevated. Check the live AQI card for the current reading.
October–February, except early mornings — winter dawn smog gives the worst AQI of the day.
May frequently touches 44°C — this is one of the state's heat stations.
