Guarabira's air quality reflects the Paraíba coastal Agreste zone, with vehicle emissions from the BR-230 and surrounding sugarcane, agave, and food processing operations contributing local sources. Atlantic trade winds from the Paraíba coast provide background maritime ventilation, while the sugarcane belt's harvest season processing adds organic aerosols and the coastal metropolitan expansion of the greater João Pessoa corridor drives increasing vehicle emissions throughout the year.
