Macaíba's air quality reflects the Rio Grande do Norte metropolitan area adjacent to Natal, with vehicle emissions from the BR-304 and surrounding industrial and residential growth contributing local sources in this major Natal satellite. Atlantic trade winds from the Rio Grande do Norte coast provide general background maritime ventilation, while the growing Natal metropolitan expansion and the industrial character of the Macaíba logistics corridor drive increasing local emissions throughout the year.
