Zihuatanejo's air quality benefits from its exceptional Pacific Ocean and Zihuatanejo Bay coastal position, with consistent Pacific maritime breezes providing reliable ventilation along this famous resort bay. Vehicle traffic on surrounding roads and the fishing port and tourism corridor contribute modest local sources, while the outstanding Pacific coastal exposure and the Ixtapa-Zihuatanejo resort character generally maintain good to moderate conditions throughout most of the year.

When is air pollution at its worst in Zihuatanejo?

In Zihuatanejo, road traffic, harbour and shipping traffic, as well as seasonal tourism traffic are the main local sources, with conditions worsening when maritime winds die down. Sea breezes typically keep conditions in check, except during still weather. This natural ventilation is one reason coastal areas often see better readings than inland cities.

Are air quality levels in Zihuatanejo 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.
