Culiacán's air quality reflects the flat Sinaloa coastal plain's Humaya-Tamazula River corridor at 60 metres, with vehicle traffic on surrounding roads and the agricultural, food processing, and services corridor contributing local sources. Consistent Pacific sea breezes and Gulf of California winds provide reliable maritime ventilation, while the flat coastal terrain allows reasonable dispersal and Culiacán generally maintains moderate to good northwestern Mexican Pacific coastal plain readings throughout most of the year.

When is air pollution at its worst in Culiacán?
Air quality in Culiacán tends to be worse when vehicle traffic, textile and manufacturing operations, together with agricultural burning build up and the sea breeze weakens. 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 Culiacán 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.
