João Pessoa's air quality benefits from consistent Atlantic trade winds off the Paraíba coast that provide reliable ventilation across this compact northeastern Brazilian city, one of Brazil's easternmost state capitals. Vehicle emissions from the growing metropolitan area are the primary local source, while the coastal position and consistent onshore winds keep readings generally among the more favourable for major Brazilian cities.
