Worst air pollution Mount Benson, today and tomorrow

On 17 September 2026, overall air quality in Mount Benson is moderate. AQI is the main air quality indicator at 41.4/100. Pollution peaks around 9:30 AM (PM2.5: 41.4/100).

On 18 September 2026, air quality conditions in Mount Benson will be better than today, with AQI forecast at fair at 38.4/100. Pollution peaks around 10:30 PM (PM2.5: 38.4/100).

Winter tends to bring the year's worst particulate spikes here, as wood heaters and gas heating combine with still, cold air that traps smoke close to the ground. As fire season builds, bushfire smoke typically becomes the dominant summer issue around here, as hot, dry summers raise both bushfire risk and the ozone formed from strong sunlight.

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.
