Worst air pollution Estepona, today and tomorrow

On 19 July 2026, overall air quality in Estepona is poor. AQI is the main air quality indicator at 61.2/100. Pollution peaks around 6:00 PM (O3: 61.2/100).

On 20 July 2026, air quality conditions in Estepona will be similar to today, with AQI forecast at poor at 61.4/100. Pollution peaks around 8:00 PM (O3: 61.4/100).

Does air quality in Estepona vary by season? Winter is generally the most challenging season, since low wind speeds and temperature inversions prevent traffic and wood-smoke pollution from dispersing. Spring is typically when conditions begin improving, as increasing wind speeds help disperse traffic emissions before they can accumulate. The heat of summer drives up ozone formation, and dry conditions occasionally bring smoke from regional wildfires into the mix. Autumn is typically a recovery period, with increasing rainfall and cooler air gradually reducing both ozone and traffic-related pollution. 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.
