Worst air pollution Cenotaph - Melbourne, today and tomorrow

On 17 September 2026, overall air quality in Cenotaph is moderate. AQI is the main air quality indicator at 40.9/100. Pollution peaks around 11:00 PM (PM2.5: 40.9/100).

On 18 September 2026, air quality conditions in Cenotaph will be similar to today, with AQI forecast at moderate at 41.0/100. Pollution peaks around 12:00 AM (PM2.5: 41.0/100).

The heart of winter usually marks the low point for air quality across this urban stretch, when winter inversions hold traffic and heating emissions in place over the city for days at a time. Summer shifts the concern toward bushfire smoke drifting across the city, with summer's combination of heat, dry vegetation, and traffic emissions driving both ozone and periodic bushfire smoke.

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.

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.
