Windsor sits in Melbourne's inner south, close to the busy Chapel Street shopping strip, where dense traffic through this popular commercial spine is the dominant local air quality factor. Its flat, inland position offers limited natural ventilation compared with bayside suburbs a short distance away. There is no industry present. Bushfire smoke is a periodic summer risk from outer hinterland. Overall, background air quality here reflects a busy, densely built inner-city suburb with a well-known nightlife and retail strip.

When is air pollution at its worst in Windsor?
Windsor's air quality generally follows Melbourne's seasonal pattern, with summer bushfire smoke, December to March, on hot, still days the main concern, alongside a milder increase in wood-heater smoke on cold winter nights in this densely built inner suburb.
Are air quality levels in Windsor 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.
