Itanhaém's air quality benefits from its Atlantic coastal position on the São Paulo state Litoral Sul, with consistent sea breezes providing reliable maritime ventilation along this resort shoreline. Vehicle emissions from the SP-055 Padre Manoel da Nóbrega highway and the surrounding banana farming and coastal development are the primary local sources, while the Serra do Mar escarpment to the inland creates the primary topographic variation throughout the year.
