Worst air pollution Mount Stuart, today and tomorrow

On 20 September 2026, overall air quality in Mount Stuart is fair. AQI is the main air quality indicator at 35.4/100. Pollution peaks around 4:00 PM (PM2.5: 35.4/100).

On 21 September 2026, air quality conditions in Mount Stuart will be worse than today, with AQI forecast at moderate at 40.3/100. Pollution peaks around 12:00 PM (PM2.5: 40.3/100).

This area typically sees its worst air quality during the winter season, as wood heaters and gas heating combine with still, cold air that traps smoke close to the ground. The warmer months shift the main air quality risk here toward bushfire smoke and ozone, with bushfire smoke capable of pushing particulate readings well above the ozone increase from heat and sun alone.

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.
