Sanlúcar de Barrameda's air quality benefits from its exceptional Atlantic Ocean and Guadalquivir estuary position at the entrance to the river, with consistent Atlantic westerlies and the Poniente sea breeze providing powerful and reliable maritime ventilation. Vehicle traffic on the A-480 and the surrounding sherry and manzanilla wine production and fishing port are the primary local sources, while the outstanding Atlantic coastal exposure maintains generally good conditions throughout most of the year.

When is air pollution at its worst in Sanlúcar de Barrameda?
Does air quality in Sanlúcar de Barrameda vary by season? The coldest months usually see the year's poorest conditions, since calm anticyclonic weather holds local traffic and wood-burning pollution near street level. As spring progresses, wetter and windier conditions generally help flush out the traffic and heating pollution that built up over winter. Summer can bring periodic wildfire smoke on top of the usual ozone build-up from intense heat and sunshine. Autumn is typically a recovery period, with increasing rainfall and cooler air gradually reducing both ozone and traffic-related pollution. Being close to North Africa, this area is more exposed to Saharan dust intrusions, which can add to the seasonal pattern described above.
Are air quality levels in Sanlúcar de Barrameda 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.
Why doesn’t the forecast always reflect wildfire impacts?
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.
