Worst air pollution Toowoomba, today and tomorrow

On 4 August 2026, overall air quality in Toowoomba is fair. PM1 is the main pollutant at 22.8/100. Pollution peaks around 11:00 PM (NO2: 43.1/100).

On 5 August 2026, air quality conditions in Toowoomba will be better than today, with AQI forecast at medium at 43.4/100. Pollution peaks around 12:00 AM (NO2: 43.4/100).

The times most likely to bring reduced air quality are cold, still winter nights, when temperature inversions can trap smoke over the city, and dry spells in late winter and spring, when bushfires on the surrounding range country add smoke haze. Its elevated position otherwise supports generally fresh air most of the year.

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.
