Grasse experiences air quality shaped by tourist traffic and coastal industry, in a setting close to the Durance, though the Mistral wind provides powerful periodic ventilation, limiting how much pollution can build up locally. Summer brings the greatest risk of ozone build-up, as calm, hot anticyclonic conditions persist for days between Mistral episodes; winter is generally cleaner and better ventilated.
