Air quality in Caloundra is typically very good thanks to strong, consistent sea breezes off the Coral Sea and Pumicestone Passage that keep the coastal strip well ventilated. The main risks are episodic: bushfire smoke drifting in from hinterland forests during dry spells, and occasional summer haze on stagnant, humid days with limited onshore flow, though these episodes are usually short-lived. The town's compact, low-rise footprint and limited heavy industry help keep background pollution levels consistently low year-round.

When is air pollution at its worst in Caloundra?
Expect the occasional dip in air quality during prolonged dry periods in late winter and spring, when bushfire smoke from the Sunshine Coast hinterland can reach the coast, particularly on days with light or offshore winds. On most days, however, the sea breeze keeps Caloundra's air noticeably cleaner than inland parts of the region.
Are air quality levels in Caloundra 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.
