Pessac's air quality reflects the greater Bordeaux metropolitan area's southwestern suburban corridor, with vehicle traffic on the A630 motorway and the surrounding University of Bordeaux campus and technology park operations contributing local sources. Atlantic westerlies from the Gironde estuary generally provide maritime ventilation, while the Landes pine forest to the south provides a clean-air backdrop and the suburban character generally maintains moderate Bordeaux metropolitan area readings throughout the year.
