Viçosa's air quality reflects the Minas Gerais southeastern highlands at 649 metres in the Zona da Mata foothills, with vehicle emissions from the MG-280 and the UFV federal university campus and surrounding coffee and dairy farming contributing local sources. The surrounding Serra da Mantiqueira foothills create topographic variation, while Atlantic sea breezes from the nearby Espírito Santo coast provide periodic ventilation relief throughout the year.
