Teresópolis's air quality benefits from its elevated position in the Serra dos Órgãos at 872 metres above Rio de Janeiro, with the Atlantic trade winds and consistent cloud forest moisture providing relatively clean mountain air compared to coastal Rio. Vehicle emissions from the RJ-130 and tourist traffic contribute local sources, while the mountain topography creates strong diurnal ventilation patterns that flush the valley daily, and the protected National Park backdrop provides one of Rio de Janeiro state's cleanest urban environments in the higher elevation residential areas.
