A Coruña's air quality benefits from its exceptional Atlantic Ocean exposure on the Galician coast, with the powerful Galician northwesterly winds providing some of Spain's most consistent maritime ventilation. The primary local concerns are vehicle emissions from the AC-11 ring road and industrial emissions from the Repsol oil refinery at nearby Bens, while the Atlantic coastal position and consistent onshore winds generally keep A Coruña among the better air quality environments for a major Iberian industrial port city.

Frequently Asked Questions

When is air pollution at its worst in A Coruña?
How do the seasons affect air quality in A Coruña? January is frequently the most difficult month, with cold stagnant air allowing wood-smoke and exhaust to build up instead of clearing. Conditions tend to ease in spring, as more active weather systems bring the wind and rain needed to disperse ground-level pollution. Hot, dry summer conditions favour ozone formation, so afternoon readings can rise even when traffic and heating pollution are otherwise low. Air quality usually improves through autumn, as returning rains and cooling temperatures wash out summer's ozone and dust build-up. The area's maritime climate, with frequent fronts rolling in off the Atlantic, generally prevents pollution from lingering for long.
Are air quality levels in A Coruña 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.
