Toluca's air quality reflects Mexico's highest major city at 2,660 metres in the Toluca Valley, with vehicle traffic on surrounding expressways and the automotive manufacturing — Toluca being Mexico's main car production hub — and industrial corridor generating elevated NOₓ. The extreme altitude amplifies photochemical ozone formation, while the enclosed valley topography creates concentration under inversions and Toluca generally maintains moderate to elevated Mexican highland industrial metropolitan readings throughout most of the year.

Frequently Asked Questions
Is air quality bad in Toluca right now?
On 16 July 2026, overall air quality in Toluca is poor. AQI is the main air quality indicator at 60.7/100. Pollution peaks around 5:00 AM (PM10: 60.7/100).
Will air quality be worse tomorrow in Toluca?
On 17 July 2026, air quality conditions in Toluca will be similar to today, with AQI forecast at poor at 61.8/100. Pollution peaks around 4:00 AM (PM10: 61.8/100).
When is air pollution at its worst in Toluca?
Pollution in Toluca typically rises when road traffic, heavy industry such as steel, cement, or petrochemical processing, as well as light manufacturing combine, especially once temperature inversions set in over the valley. Topographic enclosure in the valley lets pollution accumulate rather than clear out. Dust carried on these winds adds substantially to particulate levels.
Are air quality levels in Toluca 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.
