Dhaka's air quality reflects the flat Bengal delta's enclosed alluvial plain position, with vehicle traffic on the Dhaka Elevated Expressway and the extraordinary garment manufacturing, brick kiln, and vehicle density generating some of South Asia's highest sustained PM2.5. The Bay of Bengal monsoon provides wet season cleansing, while the dry winter northeast monsoon concentrates brick kiln and vehicle emissions extensively and the flat delta's minimal topographic dispersal maintains Dhaka among the world's most persistently challenged major metropolitan air quality environments.

Frequently Asked Questions
Is air quality bad in Dhaka right now?
On 9 August 2026, overall air quality in Dhaka is fair. O3 is the main pollutant at 25.8/100. Pollution peaks around 7:00 PM (NO2: 47.9/100).
Will air quality be worse tomorrow in Dhaka?
On 10 August 2026, air quality conditions in Dhaka will be worse than today, with AQI forecast at poor at 60.8/100. Pollution peaks around 2:00 PM (O3: 60.8/100).
When is air pollution at its worst in Dhaka?
Dhaka usually sees its poorest air quality when traffic emissions as well as manufacturing and food processing coincide with periods when the monsoon rains ease off. Rainfall through the monsoon usually keeps levels in check. Outside the monsoon, dry-season stagnation can let pollution build up further.
Are air quality levels in Dhaka based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
