Aguadilla's air quality benefits from its exceptional Puerto Rico northwestern Atlantic and Mona Passage coastal position, with consistent northeast Atlantic and Caribbean trade winds providing reliable maritime ventilation. Vehicle traffic on surrounding roads and the tourism, light manufacturing, and services corridor contribute modest local sources, while the outstanding Caribbean coastal exposure generally maintains Aguadilla among Puerto Rico's more reliably ventilated coastal communities throughout most of the year.

When is air pollution at its worst in Aguadilla?
Aguadilla usually sees its poorest air quality when traffic on the surrounding roads, manufacturing activity, together with tourism-related traffic coincide with periods when onshore breezes fall calm. Onshore breezes usually help clear the air, but pollution can build up when winds are light. This coastal advantage is less pronounced during still, high-pressure weather.
Are air quality levels in Aguadilla 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.
