On 19 July 2026, overall air quality in Yogyakarta is very poor. AQI is the main air quality indicator at 83.8/100. Pollution peaks around 3:00 AM (NO2: 83.8/100).

On 20 July 2026, air quality conditions in Yogyakarta will be better than today, with AQI forecast at poor at 78.9/100. Pollution peaks around 4:00 AM (NO2: 78.9/100).

You're quickest to notice worse air in Yogyakarta when tropical tree and grass allergens peaks, or due to dense motorcycle and vehicle traffic in this densely populated cultural capital; the rest of the calendar year is generally more forgiving for air quality.

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.

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.
