Air Quality Index (AQI) in Bangladesh 🇧🇩

Live Air Quality Index (AQI) and PM2.5 Levels in Bangladesh

Currently, the Air Quality Index (AQI) in Dhaka, the capital of Bangladesh, is measured at a score of 52. According to the US EPA health standard, this air quality rating is categorized as Good. The current atmosphere in Dhaka is influenced by a PM2.5 (fine particulate matter) concentration of 9.8 µg/m³ and PM10 levels recorded at 10.6 µg/m³. Monitoring of gaseous pollutants shows Nitrogen Dioxide (NO2) at 16.3 µg/m³.

Beyond the primary urban hubs, atmospheric conditions and smog levels fluctuate across Bangladesh based on industrial output, traffic density, and local weather patterns. Real-time pollution data and respiratory health alerts are also being actively monitored in cities like Chattogram, Khulna, Rangpur, Comilla and Rājshāhi. Tracking these air quality metrics is essential for residents nationwide to manage outdoor exposure and maintain respiratory safety during periods of increased particulate concentration.

Air Quality Snapshot: Bangladesh Right Now

Across 49 monitored cities in Bangladesh, live air quality currently ranges from a low of 21 AQI in Cox’s Bāzār (the cleanest air right now) to a high of 78 AQI in Mymensingh (the most polluted). By US EPA health band, the nationwide distribution stands at 10 Good, 39 Moderate. The average fine-particulate (PM2.5) concentration across these cities is 12.6 µg/m³ — approximately 2.5 times the World Health Organization (WHO) annual air quality guideline of 5 µg/m³.

Pollution Monitor & AQI Forecast: Bangladesh Regions

* Air Quality Index (AQI) data for Bangladesh is calculated using the US EPA standard. Information is processed from multiple monitoring stations detecting PM2.5, PM10, and gaseous pollutants to ensure accuracy for respiratory health planning.

What Today's Readings Mean in Bangladesh

The median reading across 49 monitored cities is 55 AQI. The national spread is 57 points, from 21 in Cox’s Bāzār to 78 in Mymensingh. Average PM2.5 is 12.6 µg/m³ (2.5× the WHO annual guideline).

At least one monitored location is in the Moderate range. People unusually sensitive to air pollution may want to reduce prolonged outdoor exertion there.

Air Quality in Bangladesh — FAQ

Common questions about AQI levels, pollutants, and data sources for Bangladesh.

What is the current air quality in Bangladesh?

Live AQI readings for 49 city(ies) across Bangladesh are listed above on the US EPA 0-500 scale.

Where does Bangladesh's AQI data come from?

Real-time readings come from ground-based monitoring stations operated by national environmental agencies in Bangladesh, delivered via WeatherAPI.com and aggregated using the EPA AQI formula.

What is a healthy AQI value in Bangladesh?

On the EPA scale used worldwide, 0-50 is Good, 51-100 is Moderate, 101-150 is Unhealthy for sensitive groups, 151-200 is Unhealthy, 201-300 is Very Unhealthy, and 301-500 is Hazardous. The WHO 24-hour PM2.5 guideline is 15 μg/m³.

Why do AQI readings vary between cities in Bangladesh?

Air quality is highly local — major pollution sources (traffic, industry, dust, wildfires) cluster around cities, while wind direction and topography move them around. Comparing nearby readings on this page is the best way to see how conditions change across Bangladesh.
