Marfa experiences air quality conditions shaped chiefly by high desert dryness, and among the cleanest, clearest air in Texas. Day-to-day conditions in Marfa can still vary with local weather, wind direction, and time of year. 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 Marfa?
Air quality in Marfa shifts across the year. Typically, the cleanest air usually comes in the milder shoulder seasons of spring and autumn, while intense summer heat drives persistent ozone problems, particularly in and around the largest metro areas. Dust from West Texas can occasionally drift across the state and add to particulate levels.
Are air quality levels in Marfa 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.
