Air quality in Jakarta is driven by heavy traffic, industrial activity, and dense urban development. At times, pollution can also rise when smoke from regional fires in Sumatra and nearby areas reaches the city.

Frequently Asked Questions
Is air quality bad in Jakarta right now?
On 20 September 2026, overall air quality in Jakarta is poor. AQI is the main air quality indicator at 70.7/100. Pollution peaks around 7:00 AM (PM2.5: 70.7/100).
Will air quality be worse tomorrow in Jakarta?
On 21 September 2026, air quality conditions in Jakarta will be similar to today, with AQI forecast at poor at 62.1/100. Pollution peaks around 7:00 AM (PM2.5: 62.1/100).
When is air pollution at its worst in Jakarta?
Air pollution in Jakarta tends to be worse during peak travel periods, especially when hot, humid conditions and low wind slow dispersion. Episodes of regional haze can further increase pollution levels.
Are air quality levels in Jakarta 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.
