On the Swan River east of Perth's city centre, Optus Stadium enjoys one of the more naturally ventilated settings among Australia's major arenas, thanks to the dependable sea breeze that reaches well into the Perth basin most afternoons. The riverside parkland surrounding the stadium also helps buffer it from the tighter traffic corridors found deeper in the CBD. Western Australia's Mediterranean climate keeps air quality generally high here throughout the year, with the main seasonal blemish being the possibility of bushfire smoke settling over the region during the drier months from December to March.

When is air pollution at its worst in Optus Stadium?
Optus Stadium tends to see its poorest air quality during the peak fire danger period of December to March, the main exception to a clean record. For the rest of the year, dependable sea breezes keep pollutants from building up. Checking forecasts before a long day outdoors during that window is a sensible precaution.
Are air quality levels in Optus Stadium 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.
Why doesn’t the forecast always reflect wildfire impacts?
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.
