Worst air pollution Zona Zero Circuito de Motocross - Talavera de la Reina, today and tomorrow

On 9 August 2026, overall air quality in Zona Zero Circuito de Motocross is fair. O3 is the main pollutant at 32.4/100. Pollution peaks around 7:00 AM (NO2: 40.0/100).

On 10 August 2026, air quality conditions in Zona Zero Circuito de Motocross will be similar to today, with O3 forecast at fair at 33.5/100. Pollution peaks around 5:00 AM (NO2: 42.1/100).

When is air quality typically worst in Zona Zero Circuito de Motocross? December through February is often the toughest stretch, driven by temperature inversions that keep exhaust and heating smoke from dispersing on still days. Spring often marks a turning point, with increasing storminess and rainfall helping to clear accumulated exhaust and smoke from the air. Summer brings its own challenge in the form of ground-level ozone, which forms readily under strong sunshine and high temperatures, particularly during heatwaves. Conditions tend to stabilise in autumn, as cooling weather and increasing rain reduce the ozone spikes typical of summer. Away from the moderating effect of the sea, this area experiences starker seasonal air quality swings than coastal Spain.

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.
