Ubatuba's air quality benefits from its Atlantic coastal position on the São Paulo state northern coast, with consistent Atlantic sea breezes providing reliable maritime ventilation along this scenic Costa Verde resort and ecotourism destination. Vehicle emissions from the SP-099 Tamoios highway are the primary local source, while the surrounding Serra do Mar Atlantic Forest reserve provides an outstanding clean-air backdrop and the coastal position generally maintains excellent to good conditions throughout the year.
