Worst air pollution Circuito de Jerez - Jerez de la Frontera, today and tomorrow

On 9 August 2026, overall air quality in Circuito de Jerez is fair. AQI is the main air quality indicator at 35.3/100. Pollution peaks around 4:00 PM (O3: 35.3/100).

On 10 August 2026, air quality conditions in Circuito de Jerez will be better than today, with AQI forecast at medium at 40.3/100. Pollution peaks around 5:00 PM (O3: 40.3/100).

How does air quality change throughout the year in Circuito de Jerez? Winter high-pressure systems tend to produce the year's worst episodes, as still air traps traffic fumes and heating smoke at 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. Summer can bring periodic wildfire smoke on top of the usual ozone build-up from intense heat and sunshine. Early autumn can still bring warm, stagnant spells before the season's returning rain and wind begin clearing the air. The south's long, hot summers and occasional calima dust events from across the Strait tend to intensify the usual seasonal swings.

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.
