Montpellier's air quality benefits from its Mediterranean coastal position and the Tramontane and Mistral winds that periodically deliver powerful clean air from the northwest, providing some of France's most effective natural ventilation events. Vehicle traffic on the surrounding motorway network and summer tourist traffic are the primary local sources, while the enclosed Languedoc coastal plain under calm summer anticyclonic conditions allows ozone to accumulate from vehicle and agricultural emissions.
