Puerto Vallarta's air quality benefits from its exceptional Pacific Ocean and Banderas Bay coastal position in Jalisco, with consistent Pacific maritime breezes and the famous Banderas Bay sea breezes providing reliable ventilation. Vehicle traffic on surrounding roads and the concentrated tourism, resort, and services corridor contribute seasonal local sources, while the outstanding Pacific coastal exposure and the Sierra Madre Occidental rising dramatically inland create dramatic topographic variation and Puerto Vallarta generally maintains good to moderate conditions throughout most of the year.

When is air pollution at its worst in Puerto Vallarta?
The biggest local contributors to pollution in Puerto Vallarta are traffic emissions together with seasonal tourism traffic, particularly once maritime winds die down. Maritime airflow normally ventilates the area well, though calmer spells let levels rise. This coastal advantage is less pronounced during still, high-pressure weather.
Are air quality levels in Puerto Vallarta 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.
Why doesn’t the forecast always reflect wildfire impacts?
Airmine’s forecast uses CAMS (Copernicus Atmosphere Monitoring Service) as its background atmospheric model. While CAMS includes wildfire emissions, these are derived from satellite observations and are not available in real time. During rapidly evolving wildfire events, there may therefore be a delay before increased emissions are incorporated into the model. As a result, the forecast may temporarily underestimate PM₂.₅ and other pollutants associated with wildfire smoke.
During rapidly evolving wildfire events, CAMS may lag by approximately 1–2 days before increased wildfire emissions are fully represented, which can lead to temporary underestimation of PM₂.₅ concentrations in Airmine’s forecast.
