Worst air pollution Cuenca, today and tomorrow

On 9 August 2026, overall air quality in Cuenca is fair. AQI is the main air quality indicator at 32.4/100. Pollution peaks around 3:00 PM (O3: 32.4/100).

On 10 August 2026, air quality conditions in Cuenca will be similar to today, with AQI forecast at fair at 33.5/100. Pollution peaks around 3:00 PM (O3: 33.5/100).

How does air quality change throughout the year in Cuenca? Cold, windless spells in December and January are usually when conditions dip most, as heating emissions and traffic fumes accumulate under a stable atmosphere. March through May tends to see steady improvement, with more unsettled weather patterns helping disperse traffic and heating pollution. During summer, strong sunlight and high temperatures accelerate ozone formation, occasionally offsetting the drop in traffic and heating-related emissions. Autumn typically starts mild and can still see occasional ozone or dust episodes before rain and cooler temperatures gradually restore cleaner conditions. The interior's dry continental climate means winter inversions and summer heat both tend to hit harder than along the coast.

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.
