Worst air pollution Breckenridge, today and tomorrow

On 9 August 2026, overall air quality in Breckenridge is fair. AQI is the main air quality indicator at 35.7/100. Pollution peaks around 10:00 AM (O3: 35.7/100).

On 10 August 2026, air quality conditions in Breckenridge will be similar to today, with AQI forecast at fair at 34.8/100. Pollution peaks around 6:00 AM (O3: 34.8/100).

Breckenridge experiences a distinct seasonal swing in air quality: a brief window in autumn tends to bring the year's best air, before winter inversions set in, but winter temperature inversions can trap cold air and pollution in valleys and basins for days at a time. Valley and basin locations are especially prone to these winter inversion episodes compared to more exposed, higher terrain.

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.
