Mexico City, April 2 – The Atmospheric Monitoring Directorate of Mexico City (CDMX) and the conurbated zone of the State of Mexico (Edomex) released its latest air quality report yesterday, April 1, at 3:00 PM. The report indicates that the air quality is currently ‘Very Poor,’ signifying a ‘Very High’ risk to health, particularly for vulnerable groups such as children, the elderly, and individuals with pre-existing respiratory conditions.
Air Quality Status: ‘Very Poor’ Across the Metropolitan Area
The continuous monitoring by the Directorate, which updates hourly, revealed concerning levels of air pollution. This status necessitates significant precautions for all residents engaging in outdoor activities. Authorities employ these reports to implement environmental measures, including environmental contingencies and the ‘Double Hoy No Circula’ program (a vehicle restriction policy).
In addition to air quality, the report also highlighted a high Ultraviolet (UV) Ray Index, reaching level 7. This level indicates that ‘protection is needed’ for anyone spending time outdoors.
Recommendations for Public Safety
Given the current conditions, Mexico City authorities have issued the following recommendations:
- Protection against UV radiation damage is required.
- Wear long-sleeved cotton clothing, a hat, and UV-filtering glasses.
- Apply sunscreen with an SPF of 30+.
- Try to stay in the shade or indoors.

Understanding Air Quality Levels and Health Risks

- Good (Green): Minimal health risk; all individuals can enjoy outdoor activities.
- Acceptable (Yellow): Sensitive individuals may experience respiratory symptoms; those with comorbidities should limit vigorous outdoor physical activity.
- Poor (Orange): Increased probability of respiratory symptoms in sensitive individuals; higher risk of exacerbation of respiratory and cardiac diseases, and increased likelihood of premature deaths in individuals with heart or lung conditions.
- Very Poor (Red): Aggravated respiratory symptoms in sensitive populations and individuals with lung disease; exacerbated cardiovascular symptoms, such as chest pain, in heart patients; increased probability of premature deaths in individuals with heart or lung disease.
- Extremely Poor (Purple): Significant increase in the probability of severe respiratory symptoms in the general population; serious respiratory effects and aggravation of symptoms in sensitive individuals and those with lung disease; exacerbated cardiovascular symptoms in heart patients and increased probability of premature death in individuals with lung and heart disease.
Sensitive groups, as defined by authorities, include children, the elderly, individuals with nutritional deficiencies, people who perform outdoor activities, cyclists, and outdoor workers.
