CommBank Stadium sits in Parramatta, well inland in Western Sydney, a position that receives far less coastal sea-breeze ventilation than stadiums closer to the harbour, allowing heat and vehicle emissions from event-day traffic to build more readily on still days. Summer ozone formation is more pronounced here than at coastal Sydney venues, reflecting the well-documented western-Sydney pattern. There is no industry immediately nearby. Overall, background air quality reflects this inland Sydney precinct's warmer, more stagnant conditions.

When is air pollution at its worst in CommBank Stadium?
CommBank Stadium, in Sydney's inland west, can see somewhat more pronounced bushfire smoke during summer, December to March, than venues closer to the harbour, along with occasional winter wood-heater smoke on cold, still nights. Outside these periods, expect generally clear conditions for events.
Are air quality levels in CommBank Stadium 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.
