Air quality in Coffs Harbour is generally good, helped by regular onshore breezes off the Pacific that ventilate the coastal strip. The main seasonal concern is bushfire smoke from the surrounding forested escarpment and hinterland, most likely in the drier months from late winter through spring, alongside minor traffic emissions along the Pacific Highway corridor, which passes directly through the city. The escarpment behind the city can occasionally channel smoke down toward the coast on certain wind patterns.

When is air pollution at its worst in Coffs Harbour?
The period most likely to bring reduced air quality is late winter into spring, when bushfires in the hinterland forests can blanket the city in smoke, particularly during dry, wind-still spells. For the rest of the year, sea breezes keep the coastal air clear, making conditions generally reliable for outdoor activity.
Are air quality levels in Coffs Harbour 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.
