Mazatlán's air quality benefits from its exceptional Pacific Ocean and Estero de Urías coastal position in Sinaloa, with consistent Pacific maritime breezes and the famous Mazatlán El Norte winds providing reliable ventilation. Vehicle traffic on surrounding roads and the shrimp fishing port, tourism, and manufacturing corridor contribute modest local sources, while the outstanding Pacific coastal exposure generally maintains Mazatlán among Mexico's more reliably ventilated major Pacific resort port cities throughout most of the year.

When is air pollution at its worst in Mazatlán?
Pollution in Mazatlán typically rises when traffic on the surrounding roads, manufacturing activity, along with port and shipping activity combine, especially once onshore breezes fall calm. Sea breezes typically keep conditions in check, except during still weather. This coastal advantage is less pronounced during still, high-pressure weather.
Are air quality levels in Mazatlán based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
