Alpe d'Huez experiences air quality shaped by valley motorway traffic and light industry, in a setting close to the Allier, while mountain valley winds alternate with calm temperature inversions, which provides a natural check on pollution build-up. Winter is usually the toughest season, as cold air settles in the valleys and traps emissions for days, while summer sees better dispersion apart from occasional ozone build-up lower down.
