Worst air pollution Mittagong, today and tomorrow

On 5 August 2026, overall air quality in Mittagong is good. AQI is the main air quality indicator at 15.8/100. Pollution peaks around 4:00 PM (O3: 15.8/100).

On 6 August 2026, air quality conditions in Mittagong will be worse than today, with AQI forecast at medium at 44.9/100. Pollution peaks around 7:00 PM (NO2: 44.9/100).

Mittagong's elevation and cool climate make wood-heater smoke the main issue, building up on calm winter nights when smoke settles into the valley instead of dispersing. Summer bushfire smoke is the other seasonal risk, arriving with dry northerlies between December and March. Most days remain clear, so the practical advice is to watch forecasts around both seasonal windows.

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.
