Claremont sits close to the Swan River in Perth's western suburbs, benefiting from the same reliable afternoon sea breeze that ventilates much of the western corridor, keeping background air quality consistently good. Traffic concentrates around the suburb's commercial centre and train station rather than spreading widely. There is no industry present. Bushfire smoke is a periodic summer risk from the Darling Range further east. Overall, this leafy, low-density riverside suburb enjoys clean air for most of the year.

When is air pollution at its worst in Claremont?
Claremont's air quality is usually excellent, thanks to the steady afternoon sea breeze that sweeps through this western suburb most of the year. The exception is summer, from December through March, when bushfire smoke can occasionally drift in on hot, windless mornings before the breeze picks up. Residents should expect only brief, smoke-related dips rather than a sustained poor-air season.
Are air quality levels in Claremont 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.
