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.

Frequently Asked Questions
Is air quality bad in Mazatlán right now?
On 9 August 2026, overall air quality in Mazatlán is very poor. AQI is the main air quality indicator at 81.9/100. Pollution peaks around 5:00 PM (PM10: 81.9/100).
Will air quality be worse tomorrow in Mazatlán?
On 10 August 2026, air quality conditions in Mazatlán will be similar to today, with AQI forecast at very poor at 82.1/100. Pollution peaks around 7:00 PM (PM10: 82.1/100).
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.
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.
