Worst air pollution La Viña - Cádiz, today and tomorrow

On 9 August 2026, overall air quality in La Viña is fair. AQI is the main air quality indicator at 38.9/100. Pollution peaks around 6:00 PM (O3: 38.9/100).

On 10 August 2026, air quality conditions in La Viña will be better than today, with AQI forecast at medium at 40.4/100. Pollution peaks around 6:00 PM (O3: 40.4/100).

How do the seasons affect air quality in La Viña? Winter mornings are frequently the year's most polluted, as fog and calm conditions trap traffic fumes and smoke from wood stoves close to the ground. Spring is typically when conditions begin improving, as increasing wind speeds help disperse traffic emissions before they can accumulate. Hot, dry summer conditions favour ozone formation, so afternoon readings can rise even when traffic and heating pollution are otherwise low. Conditions generally improve through autumn as cooling temperatures reduce ozone formation and returning rains help disperse remaining pollutants. Southern Spain's high summer temperatures, combined with periodic dust blown in from North Africa, tend to sharpen the seasonal contrasts here.

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.
