Worst air pollution Wimmera River - Little Desert, today and tomorrow

On 17 September 2026, overall air quality in Wimmera River is moderate. AQI is the main air quality indicator at 42.8/100. Pollution peaks around 9:00 AM (PM2.5: 42.8/100).

On 18 September 2026, air quality conditions in Wimmera River will be better than today, with AQI forecast at fair at 32.4/100. Pollution peaks around 2:00 AM (PM2.5: 32.4/100).

Winter tends to bring the year's worst particulate spikes here, as cold, still air holds wood smoke and heating emissions close to the ground through winter. Warmer months bring a different problem: smoke haze from nearby bushfires, as periods of bushfire smoke punctuate an otherwise steady rise in ozone through the summer months. The transitional months of spring and autumn typically see the year's lowest particulate and ozone levels.

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.
