Air Quality Index (AQI) in Eritrea 🇪🇷

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

Currently, the Air Quality Index (AQI) in Asmara, the capital of Eritrea, is measured at a score of 73. According to the US EPA health standard, this air quality rating is categorized as Moderate. The current atmosphere in Asmara is influenced by a PM2.5 (fine particulate matter) concentration of 21.0 µg/m³ and PM10 levels recorded at 76.8 µg/m³. Monitoring of gaseous pollutants shows Nitrogen Dioxide (NO2) at 0.1 µg/m³.

Beyond the primary urban hubs, atmospheric conditions and smog levels fluctuate across Eritrea 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 Keren, Himora, Massawa and Assab. 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: Eritrea Right Now

Across 5 monitored cities in Eritrea, live air quality currently ranges from a low of 52 AQI in Himora (the cleanest air right now) to a high of 75 AQI in Assab (the most polluted). By US EPA health band, the nationwide distribution stands at 5 Moderate. The average fine-particulate (PM2.5) concentration across these cities is 18.5 µg/m³ — approximately 3.7 times the World Health Organization (WHO) annual air quality guideline of 5 µg/m³.

* Air Quality Index (AQI) data for Eritrea 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 Eritrea

The median reading across 5 monitored cities is 73 AQI. The national spread is 23 points, from 52 in Himora to 75 in Assab. Average PM2.5 is 18.5 µg/m³ (3.7× 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 Eritrea — FAQ

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

What is the current air quality in Eritrea?

Live AQI readings for 5 city(ies) across Eritrea are listed above on the US EPA 0-500 scale.

Where does Eritrea's AQI data come from?

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

What is a healthy AQI value in Eritrea?

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 Eritrea?

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 Eritrea.
