Home to the Port Kembla steelworks, Wollongong's air quality is distinctively shaped by industrial emissions from this major steel and coal-export precinct, compounded by the Illawarra escarpment, which can trap pollutants against the narrow coastal strip on still days. Prevailing onshore winds generally disperse pollutants out to sea for much of the year, but under still or offshore wind conditions the narrow coastal strip beneath the escarpment can trap steelworks and coal-related particulate emissions close to the ground, an effect authorities and researchers have long monitored in this heavy-industry corridor.

Frequently Asked Questions
Is air quality bad in Wollongong right now?
On 5 August 2026, overall air quality in Wollongong is fair. AQI is the main air quality indicator at 31.3/100. Pollution peaks around 7:00 PM (NO2: 31.3/100).
Will air quality be worse tomorrow in Wollongong?
On 6 August 2026, air quality conditions in Wollongong will be worse than today, with AQI forecast at very poor at 80.0/100. Pollution peaks around 10:00 PM (NO2: 80.0/100).
When is air pollution at its worst in Wollongong?
Air quality is typically worst on still days when the escarpment traps steelworks and traffic emissions against the coastal strip, particularly in suburbs closest to Port Kembla; onshore sea breezes usually help disperse this haze by the afternoon.
Are air quality levels in Wollongong 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.
