Ceará-Mirim's air quality reflects the Rio Grande do Norte coastal metropolitan zone north of Natal, with consistent Atlantic trade winds providing reliable maritime ventilation. Vehicle emissions from the BR-406 and surrounding sugarcane and salt flat operations contribute local sources, while the coastal position and consistent northeast trade winds generally maintain favourable readings and the Natal metropolitan expansion drives increasing vehicle emissions throughout the year.
