The air quality in the Mexico City Metropolitan Area was classified as "Good" this Sunday, November 1, according to the 04:00 report issued by the Atmospheric Monitoring Directorate of Mexico City. The Aire y Salud index of the capital government indicates that the risk for people engaging in outdoor activities is "Low", including sensitive groups.
- Air quality: "Good" in Mexico City and the State of Mexico, with a "Low" health risk.
- UV rays: level 0, so no protection is needed against sun intensity.
- Stations: several boroughs and municipalities appear without data or under maintenance, both in the capital and in Mexico State.
Recommendations and solar radiation
With this outlook, capital authorities stated that outdoor activities can be carried out without restrictions. As for the Ultraviolet Ray index, it reached level 0, meaning "no protection needed" against sun intensity.
Atmospheric monitoring also serves as the basis for activating measures such as the Environmental Contingency and the Double Hoy No Circula, so checking the report before leaving home is useful for planning the day.

The underlying challenge: PM2.5 particles
Mexico ranks among the Latin American countries with the highest air pollution, and Mexico City slightly exceeds Santiago de Chile in fine particle concentration. The 2024 World Air Quality Report, prepared by IQAir, warns that air pollution in the country is a significant problem, mainly due to the high concentration of fine PM2.5 particles, the most dangerous for health.
In 2024, the PM2.5 concentration in Mexico was approximately 3.5 times higher than the annual reference value recommended by the World Health Organization (WHO). The main pollutant in the country and in cities such as Monterrey is PM2.5, composed of organic chemical substances, dust, soot, and metals from vehicles, factories, and material burning. These microscopic particles can enter the bloodstream and are associated with respiratory, cardiovascular, and other serious conditions.
Sunday's favorable report contrasts with that structural diagnosis: although the day allows outdoor activities without significant risk, constant monitoring and emission reduction remain the core to sustaining air quality in the Mexico City Metropolitan Area.
