Katanning sits in the Great Southern agricultural region of Western Australia, where dust from surrounding grazing and cropping land, including one of the state's largest sheep saleyards, is the most noticeable air quality factor during dry, windy periods. The region benefits from a more consistent southern sea-breeze influence than deeper inland Wheatbelt towns, supporting generally clean background air. Bushfire smoke is a lesser summer risk from surrounding bushland. There is no heavy industry, keeping baseline pollution levels low.

Is air quality bad in Katanning right now?
On 4 August 2026, overall air quality in Katanning is fair. AQI is the main air quality indicator at 25.6/100. Pollution peaks around 11:00 PM (NO2: 25.6/100).
Will air quality be worse tomorrow in Katanning?
On 5 August 2026, air quality conditions in Katanning will be better than today, with AQI forecast at medium at 44.5/100. Pollution peaks around 8:00 PM (NO2: 44.5/100).
When is air pollution at its worst in Katanning?
Katanning's inland Great Southern location means it gets less benefit from coastal sea breezes, so summer bushfire smoke (December–March) from surrounding farmland and bushland is the main seasonal risk. Dust can also rise during dry, windy spells. Outside summer, expect the clean air typical of this wheatbelt-fringe district.
Are air quality levels in Katanning 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.
