Toledo's air quality in Spain benefits from the elevated Castilian Meseta position at 529 metres above the Tagus gorge, with the surrounding plateau providing generally good wind dispersal. Vehicle traffic on the A-42 national road and tourism traffic are the primary local sources, while the open Castilian plain and Atlantic westerlies generally prevent significant pollution accumulation in this historic UNESCO heritage capital throughout the year.

When is air pollution at its worst in Toledo?
How do the seasons affect air quality in Toledo? 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. As spring progresses, wetter and windier conditions generally help flush out the traffic and heating pollution that built up over winter. Hot, stagnant summer air favours ozone formation, and dry vegetation nearby occasionally adds wildfire smoke to the mix during peak heat. As autumn progresses, cooler temperatures and more frequent rain tend to bring air quality back toward its yearly average. Away from the moderating effect of the sea, this area experiences starker seasonal air quality swings than coastal Spain.
Are air quality levels in Toledo 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.
