Cuautitlán's air quality reflects Mexico City's northwestern metropolitan industrial corridor at 2,262 metres in the Valley of Mexico, with vehicle traffic on surrounding roads and the manufacturing, automotive, and dense industrial corridor generating elevated PM2.5 under the valley's persistent inversions. The enclosed Valley of Mexico's topographic trapping compounds all emissions extensively, while the industrial manufacturing character maintains Cuautitlán among Mexico City metropolitan area's more persistently industrial northwestern urban environments throughout the year.

Frequently Asked Questions
Is air quality bad in Cuautitlán right now?
On 9 August 2026, overall air quality in Cuautitlán is poor. AQI is the main air quality indicator at 74.5/100. Pollution peaks around 6:00 PM (PM10: 74.5/100).
Will air quality be worse tomorrow in Cuautitlán?
On 10 August 2026, air quality conditions in Cuautitlán will be better than today, with AQI forecast at medium at 58.0/100. Pollution peaks around 10:00 PM (PM10: 58.0/100).
When is air pollution at its worst in Cuautitlán?
Pollution in Cuautitlán typically rises when vehicle traffic along with textile and manufacturing operations combine, especially once temperature inversions set in over the valley. The surrounding valley terrain holds pollutants near the surface rather than letting them disperse. These wind events can carry dust in from the surrounding arid landscape.
Are air quality levels in Cuautitlán 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.
