Worst air pollution A Coruña, today and tomorrow

On 9 August 2026, overall air quality in A Coruña is fair. AQI is the main air quality indicator at 34.6/100. Pollution peaks around 2:00 PM (O3: 34.6/100).

On 10 August 2026, air quality conditions in A Coruña will be similar to today, with AQI forecast at fair at 31.1/100. Pollution peaks around 5:00 PM (O3: 31.1/100).

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.

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.

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.
