Cholet's air quality benefits from the flat Vendée-Maine-et-Loire bocage position, with consistent Atlantic westerlies from the nearby Loire-Atlantique coast providing reliable ventilation. Vehicle traffic on the A87 motorway and the surrounding shoe and clothing manufacturing industry contribute the primary local sources, while the flat western French landscape and the Atlantic coastal proximity generally maintain Cholet among France's more moderate western urban environments throughout most of the year.
