Air quality in Busselton is generally very good, supported by consistent sea breezes off Geographe Bay and the Indian Ocean and a lack of significant industry. As a popular tourist and coastal residential town, background pollution sources are minimal. The main seasonal issue is bushfire smoke during the drier summer months, when fires in surrounding forest country can occasionally reduce air quality and visibility.

When is air pollution at its worst in Busselton?
The times to watch for reduced air quality in Busselton are during summer bushfire episodes, typically December to March, when smoke from forest fires in the southwest region can drift over the town. Outside of these events, the steady coastal breeze off Geographe Bay generally keeps conditions clear, making the cooler, wetter months the most reliably clean for outdoor activity.
Are air quality levels in Busselton 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.
