Worst air pollution Austin, Minnesota, today and tomorrow

On 20 September 2026, overall air quality in Austin, Minnesota is moderate. AQI is the main air quality indicator at 47.5/100. Pollution peaks around 3:00 PM (NO2: 47.5/100).

On 21 September 2026, air quality conditions in Austin, Minnesota will be similar to today, with AQI forecast at moderate at 58.2/100. Pollution peaks around 3:00 PM (NO2: 58.2/100).

Austin's air quality follows a clear seasonal pattern, as the cleanest conditions usually come in winter, once the growing season dust and pollen have passed; by contrast, spring planting and autumn harvest can push particulate levels up with dust and agricultural burning. Because the land is so open here, air quality tends to bounce back quickly once the wind returns.

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.
