In Anaconda, clean southwestern Montana mountain air is the main influence on air quality, and legacy smelter contamination is a minor, localized soil concern more than an air one. Most days bring generally favorable conditions here, with occasional exceptions tied to shifting weather patterns. As with most US destinations, conditions here are best understood by season rather than by a single yearly average.

Frequently Asked Questions

Is air quality bad in Anaconda right now?

On 9 August 2026, overall air quality in Anaconda is fair. O3 is the main pollutant at 37.1/100. Pollution peaks around 11:00 PM (NO2: 48.5/100).

Will air quality be worse tomorrow in Anaconda?

On 10 August 2026, air quality conditions in Anaconda will be similar to today, with O3 forecast at fair at 36.0/100. Pollution peaks around 2:00 PM (NO2: 53.7/100).

When is air pollution at its worst in Anaconda?

Air quality across Anaconda rises and falls with the seasons, as the shoulder seasons of spring and fall typically offer the most stable, cleanest conditions; by contrast, winter temperature inversions can trap cold air and pollution in valleys and basins for days at a time. Higher-elevation, more exposed locations generally avoid the worst of the valley inversion episodes.

Are air quality levels in Anaconda based on measurements or forecasts?

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.

Why doesn’t the forecast always reflect wildfire impacts?

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.
