Is the air quality good in Dhaka?
As of February 2, 2026, at 2:00 AM PT, Dhaka, Bangladesh, is experiencing very poor air quality, with the Air Quality Index (AQI) exceeding 200. Air conditions fall within the unhealthy to very unhealthy range, driven primarily by elevated PM2.5 concentrations.
These pollution levels far exceed World Health Organization air quality guidelines and reflect Dhaka’s persistent winter smog pattern.

While air quality today is exceptionally poor, long-term data highlight the scale of the challenge. In 2024, Dhaka’s average PM2.5 concentration was 78 µg/m³, corresponding to an AQI of 162, classified as unhealthy, and measuring 15.6 times the WHO annual guideline of 5 µg/m³.
That year, Dhaka ranked as the 26th most polluted city globally, while Bangladesh was identified as the second most polluted country in the world, underscoring the country’s ongoing air quality crisis.

When will the air quality improve in Dhaka?
Short-term improvements largely depend on weather changes. Stronger winds or rainfall can temporarily disperse pollutants. However, during winter, temperature inversions, low wind speeds, and dry conditions frequently trap emissions close to the ground. As a result, air quality is expected to remain elevated and fluctuate until seasonal weather shifts arrive toward late winter or early spring.

What is causing poor air quality in Dhaka?
Dhaka’s severe winter air pollution is driven by a combination of local and regional factors. Hundreds of brick kilns operating around the city are a major source of PM2.5 emissions, particularly during the dry season (1).
Vehicular exhaust from dense traffic, construction dust, and industrial emissions further degrade air quality.
In winter, cooler temperatures and stagnant atmospheric conditions prevent pollutants from dispersing. Regional transport of pollution from neighboring areas also contributes to sustained smog episodes, compounding local emission sources.
