Telluride's air quality is shaped largely by steep canyon topography; the enclosed canyon can briefly trap wood-smoke on still winter evenings. 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.

When is air pollution at its worst in Telluride?
Air quality across Telluride rises and falls with the seasons. Typically, autumn is often the cleanest stretch, between wildfire season and the onset of winter inversions, while wildfire smoke drifting in from across the region is the main summer concern, while winter inversions can trap pollution locally. Higher-elevation, more exposed locations generally avoid the worst of the valley inversion episodes.
Are air quality levels in Telluride 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.
