Orléans' air quality benefits from the Loire valley's channelling of consistent Atlantic westerlies through central France, providing effective natural ventilation. Vehicle traffic on the A10 motorway is the primary local source, while the surrounding Sologne forest and flat Beauce agricultural plain generally allow good wind dispersal and Atlantic exposure maintains Orléans among the Loire Valley's more moderate urban environments.
