San José del Cabo's air quality benefits from its exceptional Pacific Ocean and Sea of Cortez coastal position at the Baja California Sur tip, with consistent Pacific and Gulf maritime breezes providing reliable and powerful maritime ventilation. Vehicle traffic on surrounding roads and the luxury resort tourism and marina operations contribute seasonal local sources, while the outstanding dual-coast maritime exposure generally maintains San José del Cabo among Mexico's more reliably ventilated coastal resort environments throughout most of the year.

When is air pollution at its worst in San José del Cabo?
