Fréjus' air quality benefits from its exceptional Côte d'Azur Mediterranean coastal position on the Gulf of Saint-Tropez, with consistent sea breezes from the Var coast providing reliable maritime ventilation alongside periodic Mistral wind events from the Massif de l'Estérel. Vehicle traffic on the A8 motorway and tourism traffic are the primary local sources, while the Estérel massif's distinctive red volcanic rock landscape creates dramatic topographic variation and the coastal position generally maintains moderate to good conditions.

Nearby Provencal farmland and garrigue scrub add a further seasonal factor.
Are air quality levels in Fréjus 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.
