Air Quality Index (AQI) in Niger 🇳🇪

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

Currently, the Air Quality Index (AQI) in Niamey, the capital of Niger, is measured at a score of 163. According to the US EPA health standard, this air quality rating is categorized as Unhealthy. The current atmosphere in Niamey is influenced by a PM2.5 (fine particulate matter) concentration of 72.6 µg/m³ and PM10 levels recorded at 156.5 µg/m³. Monitoring of gaseous pollutants shows Nitrogen Dioxide (NO2) at 7.2 µg/m³.

Beyond the primary urban hubs, atmospheric conditions and smog levels fluctuate across Niger 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 Maradi, Zinder, Tahoua, Agadez and Arlit. 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: Niger Right Now

Across 9 monitored cities in Niger, live air quality currently ranges from a low of 119 AQI in Dosso (the cleanest air right now) to a high of 192 AQI in Maradi (the most polluted). By US EPA health band, the nationwide distribution stands at 1 Unhealthy for Sensitive Groups, 8 Unhealthy. The average fine-particulate (PM2.5) concentration across these cities is 79.5 µg/m³ — approximately 15.9 times the World Health Organization (WHO) annual air quality guideline of 5 µg/m³.

Niger Air Quality: Major Cities Index

* Air Quality Index (AQI) data for Niger 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 Niger

The median reading across 9 monitored cities is 176 AQI. The national spread is 73 points, from 119 in Dosso to 192 in Maradi. Average PM2.5 is 79.5 µg/m³ (15.9× the WHO annual guideline).

At least one monitored location is Unhealthy. Reduce prolonged outdoor exertion and check the city reading before planning exercise or travel.

Air Quality in Niger — FAQ

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

What is the current air quality in Niger?

Live AQI readings for 9 city(ies) across Niger are listed above on the US EPA 0-500 scale.

Where does Niger's AQI data come from?

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

What is a healthy AQI value in Niger?

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 Niger?

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 Niger.
