Worst air pollution Plaza de España (Sevilla) - Sevilla, today and tomorrow

On 19 July 2026, overall air quality in Plaza de España (Sevilla) is fair. PM2.5 is the main pollutant at 34.4/100. Pollution peaks around 7:00 PM (O3: 47.0/100).

On 20 July 2026, air quality conditions in Plaza de España (Sevilla) will be similar to today, with NO2 forecast at fair at 34.0/100. Pollution peaks around 7:00 PM (O3: 57.7/100).

How do the seasons affect air quality in Plaza de España (Sevilla)? The winter months typically bring the weakest air quality of the year, as calm anticyclonic conditions trap vehicle and heating pollution near the surface. As spring progresses, wetter and windier conditions generally help flush out the traffic and heating pollution that built up over winter. Summer readings are shaped mainly by ozone, which builds under strong sun and heat, sometimes worsened by drifting wildfire smoke. Autumn is typically a recovery period, with increasing rainfall and cooler air gradually reducing both ozone and traffic-related pollution. The region's intense heat and its exposure to Saharan dust crossing the Strait mean conditions here can swing sharply from the seasonal norm.

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.
