Worst air pollution Wallan, today and tomorrow

On 25 August 2026, overall air quality in Wallan is good. AQI is the main air quality indicator at 16.6/100. Pollution peaks around 3:00 PM (O3: 16.6/100).

On 26 August 2026, air quality conditions in Wallan will be similar to today, with AQI forecast at good at 14.8/100. Pollution peaks around 1:00 PM (O3: 14.8/100).

Air quality often dips most sharply during winter in this area, when winter inversions trap local heating smoke in place for days at a time. The warmer months shift the main air quality risk here toward bushfire smoke and ozone, with summer's heat and dry vegetation together producing both elevated ozone and, at times, bushfire smoke haze.

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.
