Air Quality Index (AQI) in Mexico 🇲🇽
Live Air Quality Index (AQI) and PM2.5 Levels in Mexico
Currently, the Air Quality Index (AQI) in Mexico City, the capital of Mexico, is measured at a score of 76. According to the US EPA health standard, this air quality rating is categorized as Moderate. The current atmosphere in Mexico City is influenced by a PM2.5 (fine particulate matter) concentration of 22.6 µg/m³ and PM10 levels recorded at 22.8 µg/m³. Monitoring of gaseous pollutants shows Nitrogen Dioxide (NO2) at 72.1 µg/m³.
Beyond the primary urban hubs, atmospheric conditions and smog levels fluctuate across Mexico based on industrial output, traffic density, and local weather patterns. Real-time pollution data and respiratory health alerts are also being actively monitored in cities like Tijuana, Iztapalapa, León de los Aldama, Puebla and Ecatepec de Morelos. Tracking these air quality metrics is essential for residents nationwide to manage outdoor exposure and maintain respiratory safety during periods of increased particulate concentration.
