Worst air pollution Patraix - Valencia, today and tomorrow

On 19 July 2026, overall air quality in Patraix is fair. AQI is the main air quality indicator at 35.4/100. Pollution peaks around 1:00 PM (O3: 35.4/100).

On 20 July 2026, air quality conditions in Patraix will be similar to today, with AQI forecast at fair at 35.9/100. Pollution peaks around 7:00 PM (O3: 35.9/100).

Does air quality in Patraix vary by season? 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. Conditions generally start to recover in spring, as increasing wind and rainfall break up the stagnant air masses typical of winter. Hot, dry summer conditions favour ozone formation, so afternoon readings can rise even when traffic and heating pollution are otherwise low. Autumn is typically a recovery period, with increasing rainfall and cooler air gradually reducing both ozone and traffic-related pollution. The Mediterranean coast's sea breezes generally help disperse pollution, though summer tourism traffic and occasional Saharan dust can still push levels up.

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.
