San Baudilio de Llobregat's air quality reflects its position in the Barcelona southern metropolitan industrial corridor, with vehicle traffic on the C-31 and surrounding petrochemical and manufacturing operations contributing elevated NOₓ and industrial PM2.5. The Llobregat delta plain provides reasonable dispersal on sea breeze days, while the Collserola ridge to the north creates topographic enclosure and the Barcelona metropolitan sea breeze cycle influences the coastal corridor air quality throughout the year.

When is air pollution at its worst in San Baudilio de Llobregat?
When is air quality typically worst in San Baudilio de Llobregat? The coldest months usually see the year's poorest conditions, since calm anticyclonic weather holds local traffic and wood-burning pollution near street level. Spring often marks a turning point, with increasing storminess and rainfall helping to clear accumulated exhaust and smoke from the air. Summer's combination of intense sun and high temperatures makes ozone the main concern, occasionally compounded by wildfire smoke during dry, windy spells. The first rains of autumn typically help clear out any lingering summer dust or ozone, setting up milder conditions ahead of winter. The mild, breezy Mediterranean climate generally supports good dispersal, though summer crowds and Saharan dust intrusions can occasionally push levels higher.
Are air quality levels in San Baudilio 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.
