Cancún's air quality benefits from its exceptional Caribbean Sea and Nichupté Lagoon coastal position, with consistent Caribbean northeast trade winds providing reliable and powerful maritime ventilation along this famous Mexican resort coast. Vehicle traffic on surrounding roads and the concentrated tourism and hospitality operations contribute local sources, while the outstanding Caribbean coastal exposure and the consistent trade wind geometry generally maintain Cancún among Mexico's cleaner major coastal resort environments throughout most of the year.
