Currently, the Air Quality Index (AQI) in Singapore, the capital of Singapore, is measured at a score of 118. According to the US EPA health standard, this air quality rating is categorized as Unhealthy (Sensitive). The current atmosphere in Singapore is influenced by a PM2.5 (fine particulate matter) concentration of 42.4 µg/m³ and PM10 levels recorded at 47.5 µg/m³. Monitoring of gaseous pollutants shows Nitrogen Dioxide (NO2) at 21.7 µg/m³.
Beyond the primary urban hubs, atmospheric conditions and smog levels fluctuate across Singapore 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 Singapore, Jurong Town, Woodlands, Punggol and Kampong Pasir Ris. Tracking these air quality metrics is essential for residents nationwide to manage outdoor exposure and maintain respiratory safety during periods of increased particulate concentration.
