São Gabriel's air quality reflects the Rio Grande do Sul southern Pampa at 124 metres near the Uruguayan border, with consistent southerly Pampas winds providing generally good natural ventilation across this major wool and cattle producing region. Vehicle emissions from the BR-290 and surrounding agribusiness contribute modest local sources, while the open Pampa landscape and consistent winds generally maintain São Gabriel among Rio Grande do Sul's more moderate border region urban environments throughout most of the year.
