Worst air pollution El Actur - Zaragoza, today and tomorrow

On 19 July 2026, overall air quality in El Actur is fair. AQI is the main air quality indicator at 36.9/100. Pollution peaks around 7:00 AM (NO2: 36.9/100).

On 20 July 2026, air quality conditions in El Actur will be similar to today, with AQI forecast at fair at 35.2/100. Pollution peaks around 6:00 PM (O3: 35.2/100).

Does air quality in El Actur vary by season? The coldest months usually see the year's poorest conditions, since calm anticyclonic weather holds local traffic and wood-burning pollution near street level. Conditions generally start to recover in spring, as increasing wind and rainfall break up the stagnant air masses typical of winter. High summer temperatures and strong sun exposure drive ozone levels up, occasionally combined with smoke from nearby wildfires during dry spells. Autumn typically starts mild and can still see occasional ozone or dust episodes before rain and cooler temperatures gradually restore cleaner conditions. Away from the moderating effect of the sea, this area experiences starker seasonal air quality swings than coastal Spain.

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.
