Air Quality Index (AQI) in South Sudan 🇸🇸

Live Air Quality Index (AQI) and PM2.5 Levels in South Sudan

Currently, the Air Quality Index (AQI) in Juba, the capital of South Sudan, is measured at a score of 51. According to the US EPA health standard, this air quality rating is categorized as Good. The current atmosphere in Juba is influenced by a PM2.5 (fine particulate matter) concentration of 9.1 µg/m³ and PM10 levels recorded at 10.9 µg/m³. Monitoring of gaseous pollutants shows Nitrogen Dioxide (NO2) at 1.0 µg/m³.

Beyond the primary urban hubs, atmospheric conditions and smog levels fluctuate across South Sudan 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 Winejok, Yei, Malakal, Wau and Kuacjok. 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: South Sudan Right Now

Across 6 monitored cities in South Sudan, live air quality currently ranges from a low of 27 AQI in Wau (the cleanest air right now) to a high of 51 AQI in Juba (the most polluted). By US EPA health band, the nationwide distribution stands at 4 Good, 2 Moderate. The average fine-particulate (PM2.5) concentration across these cities is 7.1 µg/m³ — approximately 1.4 times the World Health Organization (WHO) annual air quality guideline of 5 µg/m³.

* Air Quality Index (AQI) data for South Sudan is calculated using the US EPA standard. Information is processed from multiple monitoring stations detecting PM2.5, PM10, and gaseous pollutants to ensure accuracy for respiratory health planning.

What Today's Readings Mean in South Sudan

The median reading across 6 monitored cities is 39.0 AQI. The national spread is 24 points, from 27 in Wau to 51 in Juba. Average PM2.5 is 7.1 µg/m³ (1.4× the WHO annual guideline).

At least one monitored location is in the Moderate range. People unusually sensitive to air pollution may want to reduce prolonged outdoor exertion there.

Air Quality in South Sudan — FAQ

Common questions about AQI levels, pollutants, and data sources for South Sudan.

What is the current air quality in South Sudan?

Live AQI readings for 6 city(ies) across South Sudan are listed above on the US EPA 0-500 scale.

Where does South Sudan's AQI data come from?

Real-time readings come from ground-based monitoring stations operated by national environmental agencies in South Sudan, delivered via WeatherAPI.com and aggregated using the EPA AQI formula.

What is a healthy AQI value in South Sudan?

On the EPA scale used worldwide, 0-50 is Good, 51-100 is Moderate, 101-150 is Unhealthy for sensitive groups, 151-200 is Unhealthy, 201-300 is Very Unhealthy, and 301-500 is Hazardous. The WHO 24-hour PM2.5 guideline is 15 μg/m³.

Why do AQI readings vary between cities in South Sudan?

Air quality is highly local — major pollution sources (traffic, industry, dust, wildfires) cluster around cities, while wind direction and topography move them around. Comparing nearby readings on this page is the best way to see how conditions change across South Sudan.
