Air quality in Whyalla is significantly shaped by its steelworks, one of Australia's major steel production facilities, which is a key source of local particulate and emissions alongside natural dust from the surrounding arid landscape. Spencer Gulf sea breezes help ventilate the city on most days, but conditions near the steelworks precinct can be more variable, particularly during still weather.

When is air pollution at its worst in Whyalla?
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.
Are air quality levels in Whyalla based on measurements or forecasts?
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.
