Bunbury generally enjoys good air quality thanks to its coastal position and regular sea breezes from the Indian Ocean. As WA's second-largest city with a working port and some industry, there can be localised effects from port and industrial activity, but these are typically modest. The main seasonal concern is bushfire smoke during the hot, dry summer months, when fires in surrounding forest country can affect the region.

When is air pollution at its worst in Bunbury?
Expect Bunbury's air quality to be at its most affected during summer bushfire season, roughly December to March, when smoke from forest fires in the southwest can drift across the city, and on still, hot days when port or industrial activity is more noticeable without a clearing sea breeze. Most of the year, the reliable coastal breeze keeps conditions comfortable and clear.
Are air quality levels in Bunbury 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.
