Air Quality Index (AQI) in Spain 🇪🇸
Live Air Quality Index (AQI) and PM2.5 Levels in Spain
Currently, the Air Quality Index (AQI) in Madrid, the capital of Spain, is measured at a score of 42. According to the US EPA health standard, this air quality rating is categorized as Good. The current atmosphere in Madrid is influenced by a PM2.5 (fine particulate matter) concentration of 7.6 µg/m³ and PM10 levels recorded at 11.8 µg/m³. Monitoring of gaseous pollutants shows Nitrogen Dioxide (NO2) at 12.8 µg/m³.
Beyond the primary urban hubs, atmospheric conditions and smog levels fluctuate across Spain 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 Barcelona, Sevilla, Zaragoza, Málaga and Murcia. Tracking these air quality metrics is essential for residents nationwide to manage outdoor exposure and maintain respiratory safety during periods of increased particulate concentration.
