Worst air pollution John Yeats Memorial Lookout - Willunga, today and tomorrow

On 17 September 2026, overall air quality in John Yeats Memorial Lookout is fair. AQI is the main air quality indicator at 36.2/100. Pollution peaks around 2:30 PM (PM2.5: 36.2/100).

On 18 September 2026, air quality conditions in John Yeats Memorial Lookout will be similar to today, with AQI forecast at fair at 24.5/100. Pollution peaks around 12:30 AM (PM2.5: 24.5/100).

The colder months typically bring the heaviest particulate levels of the year, 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, 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.
