Kalamunda sits in the Perth Hills at the edge of the Darling Range, an elevated, forested setting that brings a genuine bushfire smoke risk in dry summers, offset by generally good natural ventilation and a cooler climate than the Perth plain below. Wood heater smoke can build on calm winter nights given the elevation. There is no industry present. Overall, background air quality here is generally excellent outside fire season, reflecting the clean, forested hills setting on Perth's eastern fringe.

When is air pollution at its worst in Kalamunda?
Kalamunda, in the Perth Hills, sits close to forested bushland that sees regular fire activity each summer, December to March, making it one of the areas most likely to notice smoke haze during hot, dry, windy conditions. Outside summer, the elevated setting typically offers clean, fresh air.
Are air quality levels in Kalamunda 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.
