Mafra's air quality benefits from its Sintra-Cascais Natural Park hinterland position northwest of Lisbon at 306 metres, with consistent Atlantic westerlies providing reliable maritime ventilation. Vehicle traffic on the A8 motorway is the primary local source, while the surrounding Sintra-Cascais natural park's forested highlands and the Atlantic coastal proximity generally maintain Mafra among the greater Lisbon area's cleaner municipalities throughout most of the year.
