Temascalcingo's air quality reflects the flat Estado de México Lerma River highland at 2,600 metres in the Mazahua indigenous territory, with very modest traffic and agricultural operations contributing minimal local sources. The elevated highland position aids dispersal, while the Mexico City-Toluca metropolitan regional background influences the area and the indigenous agricultural character generally maintains good to moderate conditions throughout most of the year.

Frequently Asked Questions
Is air quality bad in Temascalcingo right now?
On 20 September 2026, overall air quality in Temascalcingo is very poor. AQI is the main air quality indicator at 100/100. Pollution peaks around 5:00 AM (PM10: 100/100).
Will air quality be worse tomorrow in Temascalcingo?
On 21 September 2026, air quality conditions in Temascalcingo will be similar to today, with AQI forecast at very poor at 100/100. Pollution peaks around 6:00 AM (PM10: 100/100).
When is air pollution at its worst in Temascalcingo?
Pollution in Temascalcingo typically rises when traffic on the surrounding roads along with agricultural activity combine, especially once winds are light and dispersion is poor. Day-to-day conditions here depend heavily on the weather. Conditions can otherwise vary considerably with the weather.
Are air quality levels in Temascalcingo 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.
