Praia Grande's air quality reflects its position on the São Paulo state lowland coast below the Serra do Mar escarpment, with Atlantic sea breezes generally providing good coastal ventilation. The primary local concerns are vehicle emissions from the Padre Manoel da Nóbrega highway and industrial emissions from the Santos port complex upcoast, while the Serra do Mar rising sharply inland creates topographic enclosure for the low-lying coastal strip under offshore wind conditions.
