El Prat de Llobregat's air quality reflects its position adjacent to Barcelona El Prat Airport at the Llobregat delta, with concentrated aviation and ground vehicle emissions generating elevated NOₓ and ultrafine particles in the flight path alongside vehicle traffic on the C-31 motorway. The Barcelona Bay sea breeze provides afternoon ventilation, while the airport's extraordinary passenger volume makes El Prat one of Catalonia's most aviation-influenced municipalities throughout the year.

When is air pollution at its worst in El Prat de Llobregat?
When is air quality typically worst in El Prat de Llobregat? December through February is often the toughest stretch, driven by temperature inversions that keep exhaust and heating smoke from dispersing on still days. Spring usually brings an improvement as more frequent rain and stronger winds help clear the air and wash out pollutants that built up over winter. Hot, stagnant summer air favours ozone formation, and dry vegetation nearby occasionally adds wildfire smoke to the mix during peak heat. Autumn typically starts mild and can still see occasional ozone or dust episodes before rain and cooler temperatures gradually restore cleaner conditions. Sea breezes along this stretch of coast generally support air quality, but summer holiday traffic and occasional calima dust events can interrupt that.
Are air quality levels in El Prat de Llobregat based on measurements or forecasts?
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.
