Worst air pollution Maó, today and tomorrow

On 9 August 2026, overall air quality in Maó is fair. AQI is the main air quality indicator at 31.4/100. Pollution peaks around 2:00 AM (O3: 31.4/100).

On 10 August 2026, air quality conditions in Maó will be similar to today, with AQI forecast at fair at 29.4/100. Pollution peaks around 2:00 PM (O3: 29.4/100).

How do the seasons affect air quality in Maó? Air quality often reaches its yearly low in the depths of winter, when still, cold air holds local emissions from traffic and heating close to ground level. Spring usually brings an improvement as more frequent rain and stronger winds help clear the air and wash out pollutants that built up over winter. The long, hot days of summer favour ozone build-up, which can spike on the stillest, sunniest afternoons. As autumn progresses, cooler temperatures and more frequent rain tend to bring air quality back toward its yearly average. Being on the Mediterranean coast helps with dispersal most of the year, though summer tourism and North African dust episodes remain a factor.

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.
