Esperance benefits from some of the cleanest air in Western Australia, owing to its remote south coast location, low population and strong, consistent winds off the Southern Ocean. There is minimal industry, and background air quality is typically excellent. The main seasonal factors are agricultural dust from surrounding cropping land during dry, windy periods and occasional bushfire smoke during summer.

When is air pollution at its worst in Esperance?
Expect the rare dips in Esperance's otherwise clean air to occur during hot, windy stretches in late spring and summer, when dust from surrounding cropping paddocks can become airborne, or during bushfire smoke events affecting the south coast. Outside these periods, the town's exposed position and strong Southern Ocean winds keep the air about as clear as anywhere in the state.
Are air quality levels in Esperance 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.
