São João da Boa Vista's air quality reflects the São Paulo state interior plateau at 812 metres in the Sul Mineiro highlands border region, with vehicle emissions from the SP-342 and surrounding coffee, grain, and agribusiness operations contributing local sources. The elevated plateau position aids background dispersal, while dry season burning from surrounding agricultural land contributes seasonal PM2.5 variation throughout the year.
