Worst air pollution Hamilton, today and tomorrow

On 10 August 2026, overall air quality in Hamilton is good. AQI is the main air quality indicator at 12.8/100. Pollution peaks around 3:00 PM (O3: 12.8/100).

On 11 August 2026, air quality conditions in Hamilton will be similar to today, with AQI forecast at good at 13.6/100. Pollution peaks around 3:00 PM (O3: 13.6/100).

Hamilton's air quality is most affected in winter, when cold nights on the open plains encourage wood-smoke haze to settle over town, and in summer, when bushfire smoke from the Grampians or broader western Victoria can drift in during dry, windy conditions. Between these periods, the rural plains setting generally delivers clear, well-ventilated air.

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.
