Cádiz' air quality benefits from its exceptional Atlantic Ocean and Bay of Cádiz coastal position, with the Levante and Poniente winds providing some of Spain's most dramatic and consistent natural ventilation. Vehicle traffic on the A-4 and port ferry operations are the primary local sources, while the Atlantic exposure and strait geography generally maintain Cádiz among Spain's cleanest urban environments on most days.

When is air pollution at its worst in Cádiz?

How do the seasons affect air quality in Cádiz? January is frequently the most difficult month, with cold stagnant air allowing wood-smoke and exhaust to build up instead of clearing. The transition into spring usually brings cleaner air, as more frequent rain and wind reduce the buildup of local pollution. The long, hot days of summer favour ozone build-up, which can spike on the stillest, sunniest afternoons. Conditions generally improve through autumn as cooling temperatures reduce ozone formation and returning rains help disperse remaining pollutants. Southern Spain's intense summer heat and periodic Saharan dust intrusions add extra pressure on top of the usual seasonal pattern.

Are air quality levels in Cádiz 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.
