Bastia's air quality is shaped mainly by seasonal tourism traffic, with its position near the Gravona playing a role, though coastal sea breezes ventilate the island reliably, which usually keeps pollution from accumulating for long. Summer sees the heaviest traffic from tourism, though reliable sea breezes generally prevent serious build-up; winter is the cleanest season with light traffic and steady ventilation.

Nearby Corsican maquis scrubland and terraced farmland add a further seasonal factor.
Are air quality levels in Bastia 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.
