Dalkeith sits directly on the Swan River in Perth's western suburbs, an affluent, low-density riverside setting that receives the full benefit of the consistent Indian Ocean sea breeze, supporting excellent natural ventilation and very clean background air. Traffic is light, confined to local streets. There is no industry present. Bushfire smoke is a periodic summer risk from the Darling Range further inland. Overall, Dalkeith's riverside exposure and low density make it one of the cleanest-air suburbs in Perth.

When is air pollution at its worst in Dalkeith?
Perched above the river, Dalkeith typically has some of the cleanest air in Perth, courtesy of consistent onshore breezes. The main risk period is summer, December to March, when smoke from bushfires in the Perth Hills or south-west forests can reduce visibility on calm, hot days ahead of a cool change. Outside those episodes, air quality here rarely causes concern.
Are air quality levels in Dalkeith 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.
