Worst air pollution Felgueiras, today and tomorrow

On 21 July 2026, overall air quality in Felgueiras is medium. AQI is the main air quality indicator at 44.6/100. Pollution peaks around 1:00 PM (O3: 44.6/100).

On 22 July 2026, air quality conditions in Felgueiras will be worse than today, with AQI forecast at fair at 39.8/100. Pollution peaks around 4:00 PM (O3: 39.8/100).

The most noticeable dips in Felgueiras's air quality come when highland landscape oak and eucalyptus pollen peaks, or because of vehicle traffic on the A11 and local footwear, textile, and cork manufacturing; the rest of the year typically brings clearer, more consistent conditions.

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.
