Tehuacán's air quality reflects the Puebla-Oaxaca Valle de Tehuacán semi-arid valley at 1,676 metres, with vehicle traffic on surrounding roads and the garment manufacturing, mineral water, and agricultural corridor contributing local sources. The surrounding Sierras create topographic enclosure, while winter inversions create seasonal challenges and the mineral water industry's distinctive geological character adds context to this unusual semi-arid highland valley city environment throughout most of the year.

Frequently Asked Questions
Is air quality bad in Tehuacán right now?
On 9 August 2026, overall air quality in Tehuacán is poor. AQI is the main air quality indicator at 76.0/100. Pollution peaks around 9:00 PM (PM10: 76.0/100).
Will air quality be worse tomorrow in Tehuacán?
On 10 August 2026, air quality conditions in Tehuacán will be similar to today, with AQI forecast at poor at 65.5/100. Pollution peaks around 12:00 AM (PM10: 65.5/100).
When is air pollution at its worst in Tehuacán?
Pollution in Tehuacán typically rises when road traffic, textile and manufacturing operations, as well as agricultural burning combine, especially once calm, stagnant conditions settle in the surrounding valley. Topographic enclosure in the valley lets pollution accumulate rather than clear out. Strong seasonal winds can lift dust from the surrounding dry terrain and push particulate levels sharply higher.
Are air quality levels in Tehuacán 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.
