Worst air pollution Man O' War Steps - Sydney, today and tomorrow

On 17 September 2026, overall air quality in Man O' War Steps is moderate. AQI is the main air quality indicator at 41.6/100. Pollution peaks around 11:00 PM (PM2.5: 41.6/100).

On 18 September 2026, air quality conditions in Man O' War Steps will be similar to today, with AQI forecast at moderate at 51.3/100. Pollution peaks around 8:00 PM (NO2: 51.3/100).

Winter is usually when particulate matter climbs highest across the city, as cold, stagnant air traps heating and traffic emissions close to street level through the winter. The warmer months shift the main air quality risk here toward bushfire smoke and ground-level ozone, which can blanket the city for days at a time when regional bushfires are burning, on top of routine ozone formation from heat and sunlight.

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.
