Air Quality Index (AQI) in Tanzania 🇹🇿

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

Currently, the Air Quality Index (AQI) in Dodoma, the capital of Tanzania, is measured at a score of 49. According to the US EPA health standard, this air quality rating is categorized as Good. The current atmosphere in Dodoma is influenced by a PM2.5 (fine particulate matter) concentration of 8.8 µg/m³ and PM10 levels recorded at 10.5 µg/m³. Monitoring of gaseous pollutants shows Nitrogen Dioxide (NO2) at 0.3 µg/m³.

Beyond the primary urban hubs, atmospheric conditions and smog levels fluctuate across Tanzania 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 Dar es Salaam, Mwanza, Arusha, Mbeya and Morogoro. 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: Tanzania Right Now

Across 25 monitored cities in Tanzania, live air quality currently ranges from a low of 27 AQI in Morogoro (the cleanest air right now) to a high of 151 AQI in Kigoma (the most polluted). By US EPA health band, the nationwide distribution stands at 11 Good, 12 Moderate, 1 Unhealthy for Sensitive Groups, 1 Unhealthy. The average fine-particulate (PM2.5) concentration across these cities is 13.5 µg/m³ — approximately 2.7 times the World Health Organization (WHO) annual air quality guideline of 5 µg/m³.

Tanzania Air Quality: Major Cities Index

* Air Quality Index (AQI) data for Tanzania 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 Tanzania

The median reading across 25 monitored cities is 52 AQI. The national spread is 124 points, from 27 in Morogoro to 151 in Kigoma. Average PM2.5 is 13.5 µg/m³ (2.7× 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 Tanzania — FAQ

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

What is the current air quality in Tanzania?

Live AQI readings for 25 city(ies) across Tanzania are listed above on the US EPA 0-500 scale.

Where does Tanzania's AQI data come from?

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

What is a healthy AQI value in Tanzania?

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 Tanzania?

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 Tanzania.
