Maceió's air quality benefits from consistent Atlantic trade winds off the Alagoas coast that provide reliable ventilation across this northeastern Brazilian coastal city. Vehicle emissions from the metropolitan area and the Pontal da Barra industrial complex are the primary local sources, while the consistent coastal winds generally keep readings more favourable than inland Brazilian cities of comparable size.
