Vitoria-Gasteiz' air quality benefits from its elevated position on the Álava plateau in the Basque Country at 524 metres, with generally good Atlantic ventilation from Cantabrian westerlies reaching across the Basque mountains. Vehicle traffic on the A-1 and N-1 corridors and the surrounding light industrial base contribute local emissions, while the city's extensive green ring and cycling infrastructure reduce vehicle emission intensity relative to comparable Spanish cities throughout the year.

When is air pollution at its worst in Vitoria-Gasteiz?
What time of year has the cleanest air in Vitoria-Gasteiz? Cold, windless spells in December and January are usually when conditions dip most, as heating emissions and traffic fumes accumulate under a stable atmosphere. Air quality usually improves through spring, helped by more frequent frontal systems that bring rain and stronger winds to disperse local emissions. The heat of summer drives up ozone formation, and dry conditions occasionally bring smoke from regional wildfires into the mix. Conditions tend to stabilise in autumn, as cooling weather and increasing rain reduce the ozone spikes typical of summer. Frequent Atlantic weather systems mean pollution rarely has the chance to accumulate for long stretches in this area.
Are air quality levels in Vitoria-Gasteiz based on measurements or forecasts?
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.
Why doesn’t the forecast always reflect wildfire impacts?
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.
