Worst air pollution Port Augusta, today and tomorrow

On 10 August 2026, overall air quality in Port Augusta is good. AQI is the main air quality indicator at 16.9/100. Pollution peaks around 9:30 PM (NO2: 16.9/100).

On 11 August 2026, air quality conditions in Port Augusta will be similar to today, with AQI forecast at good at 15.3/100. Pollution peaks around 1:30 PM (O3: 15.3/100).

The most notable air quality drops in Port Augusta come with dust storm conditions, when strong, dry winds sweep across the surrounding plains and Spencer Gulf shoreline, most likely during hot, windy stretches in spring and summer. Expect these to be sudden, visible events rather than persistent haze, easing quickly once the wind changes. Outside of dust events, the sea breeze off the gulf generally keeps the air clear.

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.
