Air quality in Mandurah is generally good, helped by its coastal position and estuarine setting, with regular sea breezes off the Indian Ocean providing reliable ventilation. There is limited heavy industry, with the main seasonal issue being bushfire smoke from surrounding bushland during the hot, dry summer months. Its proximity to Perth means it can occasionally share in broader metropolitan pollution patterns on stagnant days.

When is air pollution at its worst in Mandurah?
The times air quality is most likely to suffer in Mandurah are during summer bushfire smoke events, roughly December to March, when fires in nearby bushland or further afield can affect the region, and on rare still, hot days when sea breeze ventilation is weaker than usual. For most of the year, the coastal breeze keeps conditions clear and comfortable.
Are air quality levels in Mandurah 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.
