Perth's air quality is among the best of any major world city, with consistent Indian Ocean sea breezes from the southwest providing outstanding natural ventilation across the Swan coastal plain. The primary concerns are bushfire smoke from the Darling Range during summer and autumn, and vehicle emissions from the city's car-dependent suburban sprawl.
