Hyères' air quality benefits from its exceptional Mediterranean Côte d'Azur coastal position adjacent to the Îles d'Hyères, with consistent Mistral wind events and Mediterranean sea breezes providing reliable ventilation. Vehicle traffic on the A57 and the Toulon-Hyères Airport's aviation operations contribute local sources, while the Maures massif creates dramatic topographic variation and the outstanding Mediterranean coastal exposure and frequent Mistral events generally maintain Hyères among the Côte d'Azur's more reliably ventilated coastal environments throughout the year.

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