Val d'Isere experiences air quality shaped by valley motorway traffic and light industry, in a setting close to the Isere, while mountain valley winds alternate with calm temperature inversions, generally keeping conditions moderate to good on most days. Winter is typically the worst season, as cold air settles in the valleys and traps traffic and heating emissions for days at a time; summer sees better dispersion but occasional ozone build-up in the lower valleys.
