Caraguatatuba's air quality benefits from its Atlantic coastal position on the São Paulo state northern coast, with consistent sea breezes providing reliable maritime ventilation along this São Sebastião Bay resort coastline. Vehicle emissions from the SP-099 Tamoios highway are the primary local source, while the Serra do Mar escarpment rising immediately inland creates dramatic topographic variation and the coastal position generally maintains good baseline conditions throughout most of the year.
