Air Quality Index (AQI) in Senegal 🇸🇳

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

Currently, the Air Quality Index (AQI) in Dakar, the capital of Senegal, is measured at a score of 23. According to the US EPA health standard, this air quality rating is categorized as Good. The current atmosphere in Dakar is influenced by a PM2.5 (fine particulate matter) concentration of 4.2 µg/m³ and PM10 levels recorded at 8.2 µg/m³. Monitoring of gaseous pollutants shows Nitrogen Dioxide (NO2) at 2.8 µg/m³.

Beyond the primary urban hubs, atmospheric conditions and smog levels fluctuate across Senegal 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 Pikine, Touba, Thiès, Thiès Nones and Kaolack. 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: Senegal Right Now

Across 18 monitored cities in Senegal, live air quality currently ranges from a low of 16 AQI in Ziguinchor (the cleanest air right now) to a high of 52 AQI in Saint-Louis (the most polluted). By US EPA health band, the nationwide distribution stands at 17 Good, 1 Moderate. The average fine-particulate (PM2.5) concentration across these cities is 4.6 µg/m³ — approximately 0.9 times the World Health Organization (WHO) annual air quality guideline of 5 µg/m³.

Senegal Air Quality: Major Cities Index

* Air Quality Index (AQI) data for Senegal 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 Senegal

The median reading across 18 monitored cities is 24.5 AQI. The national spread is 36 points, from 16 in Ziguinchor to 52 in Saint-Louis. Average PM2.5 is 4.6 µg/m³ (0.9× 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 Senegal — FAQ

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

What is the current air quality in Senegal?

Live AQI readings for 18 city(ies) across Senegal are listed above on the US EPA 0-500 scale.

Where does Senegal's AQI data come from?

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

What is a healthy AQI value in Senegal?

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 Senegal?

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 Senegal.
