Worst air pollution Whyalla, today and tomorrow

On 10 August 2026, overall air quality in Whyalla is good. AQI is the main air quality indicator at 15.6/100. Pollution peaks around 12:30 PM (O3: 15.6/100).

On 11 August 2026, air quality conditions in Whyalla will be similar to today, with AQI forecast at good at 16.3/100. Pollution peaks around 9:30 PM (O3: 16.3/100).

The times air quality is most likely to be reduced in Whyalla are during calm, still conditions when steelworks emissions and industrial dust are less readily dispersed, and during windy, dry spells when natural dust from surrounding saltbush plains adds to the mix. An active Spencer Gulf sea breeze typically helps clear the air more quickly, making breezy days generally the better ones for outdoor activity.

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.
