Geelong's air quality benefits from its position on Corio Bay, where sea breezes regularly clear local emissions from the city's port, manufacturing and transport activity. Winter wood-smoke haze can build on calm nights in residential areas away from the water, and summer bushfire smoke occasionally drifts in from the Otways or western Victoria during high fire-danger periods. Industrial history means some legacy air-quality monitoring focus, though modern readings are generally in the good-to-moderate range.

Frequently Asked Questions
Is air quality bad in Geelong right now?
On 10 August 2026, overall air quality in Geelong is good. AQI is the main air quality indicator at 19.3/100. Pollution peaks around 12:00 AM (NO2: 19.3/100).
Will air quality be worse tomorrow in Geelong?

When is air pollution at its worst in Geelong?
Geelong's air quality is most likely to suffer in summer, when bushfire smoke from the Otways, Grampians or western Victoria can drift over the city on northerly or westerly winds during fire season. Winter presents a milder challenge through wood-smoke haze on cold, still evenings in low-lying suburbs. Bay breezes generally keep the city well-ventilated the rest of the year.
Are air quality levels in Geelong 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.
