Worst air pollution Brisbane, today and tomorrow

On 4 August 2026, overall air quality in Brisbane is fair. AQI is the main air quality indicator at 31.7/100. Pollution peaks around 10:00 AM (NO2: 31.7/100).

On 5 August 2026, air quality conditions in Brisbane will be similar to today, with PM1 forecast at fair at 29.7/100. Pollution peaks around 6:00 AM (NO2: 43.1/100).

Air quality in Brisbane is typically at its most challenged during the dry season's bushfire smoke episodes, usually August through November, and on hot, still summer days when ozone can build under strong sun and light winds. The Moreton Bay sea breeze usually helps clear the air by afternoon on most days, so mornings during fire season are often the more affected period for sensitive groups.

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.
