Air Quality Index (AQI) in Saudi Arabia 🇸🇦

Live Air Quality Index (AQI) and PM2.5 Levels in Saudi Arabia

Currently, the Air Quality Index (AQI) in Riyadh, the capital of Saudi Arabia, is measured at a score of 168. According to the US EPA health standard, this air quality rating is categorized as Unhealthy. The current atmosphere in Riyadh is influenced by a PM2.5 (fine particulate matter) concentration of 79.9 µg/m³ and PM10 levels recorded at 380.0 µg/m³. Monitoring of gaseous pollutants shows Nitrogen Dioxide (NO2) at 38.9 µg/m³.

Beyond the primary urban hubs, atmospheric conditions and smog levels fluctuate across Saudi Arabia 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 Jeddah, Mecca, Medina, Dammam and Sulţānah. Tracking these air quality metrics is essential for residents nationwide to manage outdoor exposure and maintain respiratory safety during periods of increased particulate concentration.

Air Quality Snapshot: Saudi Arabia Right Now

Across 35 monitored cities in Saudi Arabia, live air quality currently ranges from a low of 57 AQI in Tabuk (the cleanest air right now) to a high of 197 AQI in Al Jubayl (the most polluted). By US EPA health band, the nationwide distribution stands at 19 Moderate, 4 Unhealthy for Sensitive Groups, 12 Unhealthy. The average fine-particulate (PM2.5) concentration across these cities is 49.9 µg/m³ — approximately 10.0 times the World Health Organization (WHO) annual air quality guideline of 5 µg/m³.
