Seville's air quality benefits from the Guadalquivir valley's channelling of Atlantic westerlies through the city on prevailing wind days, providing reliable natural ventilation. Summer heat driving ozone formation from vehicle emissions and the enclosed valley geography under calm conditions are the primary warm-season concerns, while winter inversions can occasionally trap emissions across the low-lying urban basin.

When is air pollution at its worst in Sevilla?
When is air quality typically worst in Sevilla? Winter mornings are frequently the year's most polluted, as fog and calm conditions trap traffic fumes and smoke from wood stoves close to the ground. As spring progresses, wetter and windier conditions generally help flush out the traffic and heating pollution that built up over winter. Summer heat and intense sunlight drive photochemical ozone production, which can push afternoon air quality readings higher despite reduced winter-style pollution sources. Autumn usually sees a steady return to cleaner conditions as the ozone-favouring heat of summer fades and rainfall picks up. Being close to North Africa, this area is more exposed to Saharan dust intrusions, which can add to the seasonal pattern described above.
Are air quality levels in Sevilla 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.
