Worst air pollution Paterna, today and tomorrow

On 9 August 2026, overall air quality in Paterna is fair. AQI is the main air quality indicator at 35.7/100. Pollution peaks around 6:00 PM (O3: 35.7/100).

On 10 August 2026, air quality conditions in Paterna will be similar to today, with AQI forecast at fair at 34.8/100. Pollution peaks around 2:00 PM (O3: 34.8/100).

When is air quality typically worst in Paterna? The coldest months usually see the year's poorest conditions, since calm anticyclonic weather holds local traffic and wood-burning pollution near street level. The transition into spring usually brings cleaner air, as more frequent rain and wind reduce the buildup of local pollution. The long, hot days of summer favour ozone build-up, which can spike on the stillest, sunniest afternoons. By late autumn, air quality is usually back to more moderate levels, though the first cold snaps can bring an early hint of winter's traffic and heating pollution. The mild, breezy Mediterranean climate generally supports good dispersal, though summer crowds and Saharan dust intrusions can occasionally push levels higher.

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.
