Ferrol's air quality benefits from its exceptional Galician Ría de Ferrol coastal position, with consistent powerful Atlantic westerlies and northerlies providing reliable maritime ventilation around this major Spanish naval base. The Navantia shipbuilding operations and the surrounding heavy military and industrial character contribute local sources alongside vehicle traffic on the AG-64, while the outstanding Atlantic and ría exposure generally maintains Ferrol among Galicia's more moderate coastal urban environments throughout the year.

When is air pollution at its worst in Ferrol?
What is the yearly air quality pattern like in Ferrol? Cold, windless spells in December and January are usually when conditions dip most, as heating emissions and traffic fumes accumulate under a stable atmosphere. Spring often marks a turning point, with increasing storminess and rainfall helping to clear accumulated exhaust and smoke from the air. Summer can bring periodic wildfire smoke on top of the usual ozone build-up from intense heat and sunshine. Autumn usually sees a steady return to cleaner conditions as the ozone-favouring heat of summer fades and rainfall picks up. Proximity to the Atlantic brings enough rain and wind through most of the year to limit how long pollution episodes last here.
Are air quality levels in Ferrol 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.
