Pau's air quality benefits from its position in the Pyrenean piedmont, with the Gave de Pau river valley channelling Atlantic westerlies from the Bay of Biscay and the surrounding Pyrenees providing clean mountain air from the south. Vehicle traffic on the A64 motorway is the primary local source, while the Pyrenean foothills' consistent Atlantic influence and the valley's ventilation corridor generally maintain Pau among southwestern France's more moderate urban environments.
