Bandung's air quality reflects the Bandung Basin's severe topographic trap at 768 metres, with the surrounding volcanic mountains — Tangkuban Perahu, Burangrang, Patuha, and Malabar — creating near-complete basin enclosure that concentrates vehicle emissions from the surrounding ring roads and the textile, manufacturing, and extraordinary motorcycle density. The basin's topographic concentration under calm conditions and the volcanic SO₂ from Tangkuban Perahu's active fumaroles add a distinctive geological dimension, maintaining Bandung among Indonesia's more topographically challenged urban air quality environments throughout most of the year.

Is air quality bad in Bandung right now?
On 20 September 2026, overall air quality in Bandung is very poor. AQI is the main air quality indicator at 100/100. Pollution peaks around 12:00 AM (PM1: 100/100).
Will air quality be worse tomorrow in Bandung?
On 21 September 2026, air quality conditions in Bandung will be similar to today, with AQI forecast at very poor at 100/100. Pollution peaks around 12:00 AM (PM1: 100/100).
When is air pollution at its worst in Bandung?
People in Bandung tend to notice reduced air quality when neighbouring agricultural and tea plantation vegetation introduced urban trees pollen peaks, or because of the surrounding volcanic mountains — Tangkuban Perahu, Burangrang, Patuha, and Malabar —; things typically settle down again once the weather pattern shifts.
Are air quality levels in Bandung 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.
