Air Quality Index (AQI) in Cameroon 🇨🇲

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

Currently, the Air Quality Index (AQI) in Yaounde, the capital of Cameroon, is measured at a score of 44. According to the US EPA health standard, this air quality rating is categorized as Good. The current atmosphere in Yaounde is influenced by a PM2.5 (fine particulate matter) concentration of 8.0 µg/m³ and PM10 levels recorded at 8.3 µg/m³. Monitoring of gaseous pollutants shows Nitrogen Dioxide (NO2) at 2.1 µg/m³.

Beyond the primary urban hubs, atmospheric conditions and smog levels fluctuate across Cameroon 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 Douala, Bamenda, Bafoussam, Maroua and Ngaoundéré. 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: Cameroon Right Now

Across 26 monitored cities in Cameroon, live air quality currently ranges from a low of 31 AQI in Ébolowa (the cleanest air right now) to a high of 108 AQI in Bafoussam (the most polluted). By US EPA health band, the nationwide distribution stands at 6 Good, 18 Moderate, 2 Unhealthy for Sensitive Groups. The average fine-particulate (PM2.5) concentration across these cities is 16.5 µg/m³ — approximately 3.3 times the World Health Organization (WHO) annual air quality guideline of 5 µg/m³.

Cameroon Air Quality: Major Cities Index

* Air Quality Index (AQI) data for Cameroon 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 Cameroon

The median reading across 26 monitored cities is 57.5 AQI. The national spread is 77 points, from 31 in Ébolowa to 108 in Bafoussam. Average PM2.5 is 16.5 µg/m³ (3.3× the WHO annual guideline).

At least one monitored location is unhealthy for sensitive groups. Children, older adults, and people with heart or lung conditions should limit prolonged outdoor exertion in the affected city.

Air Quality in Cameroon — FAQ

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

What is the current air quality in Cameroon?

Live AQI readings for 26 city(ies) across Cameroon are listed above on the US EPA 0-500 scale.

Where does Cameroon's AQI data come from?

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

What is a healthy AQI value in Cameroon?

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 Cameroon?

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 Cameroon.
