Air quality in Grafton is generally good, with its riverside, low-density setting limiting industrial and traffic pollution. Seasonal bushfire smoke from surrounding forested ranges is the main concern, typically most active in late winter and spring, while agricultural burning on nearby cane and grazing land can add localised smoke at other times of year, particularly during drier stretches. The surrounding floodplain's flat, open character means smoke and haze can occasionally linger before dispersing.

Localised smoke from agricultural burning can also occur periodically, though Grafton's riverside setting generally sees good dispersion once conditions turn breezy.
Are air quality levels in Grafton 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.
