West Perth sits at the edge of the Perth CBD adjoining Kings Park, a large bushland reserve that both provides significant green buffer and represents a bushfire smoke risk in dry summer conditions. Office-district traffic is the main day-to-day emissions source. Sea-breeze ventilation reaches the area reasonably well given its proximity to the river and the western suburbs corridor. There is no other industry present. Overall, background air quality here is generally good, moderated by business-district traffic.

When is air pollution at its worst in West Perth?
West Perth typically enjoys clean air for most of the year, with summer bushfire smoke the chief exception. From December through March, hot and windless mornings can allow haze from fires in the surrounding hills or forests to settle over this inner suburb before the sea breeze clears it each afternoon. Outside fire season, air quality is rarely an issue here.
Are air quality levels in West Perth 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.
