Granja's air quality benefits from its Ceará Atlantic coastal position near the Piauí border, with consistent northeast trade winds providing reliable maritime ventilation along this fishing and coconut farming coastline. Vehicle emissions from the CE-085 and surrounding agricultural operations contribute modest local sources, while the coastal position and consistent trade winds generally maintain Granja among Ceará's cleaner coastal municipalities throughout most of the year.
