Worst air pollution Catedral de Sevilla - Sevilla, today and tomorrow

On 19 July 2026, overall air quality in Catedral de Sevilla is fair. PM2.5 is the main pollutant at 25.3/100. Pollution peaks around 7:00 PM (O3: 47.0/100).

On 20 July 2026, air quality conditions in Catedral de Sevilla will be similar to today, with PM2.5 forecast at fair at 20.5/100. Pollution peaks around 7:00 PM (O3: 57.7/100).

Does air quality in Catedral de Sevilla vary by season? December through February is often the toughest stretch, driven by temperature inversions that keep exhaust and heating smoke from dispersing on still days. Spring is typically a transitional season, as milder, windier weather starts clearing out the pollutants that accumulate during winter's calm spells. The long, hot days of summer favour ozone build-up, which can spike on the stillest, sunniest afternoons. Autumn usually sees a steady return to cleaner conditions as the ozone-favouring heat of summer fades and rainfall picks up. This area's proximity to North Africa means Saharan dust episodes can arrive at almost any time of year, layering onto the seasonal pattern.

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.
