Air Quality Index (AQI) in Nicaragua 🇳🇮

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

Currently, the Air Quality Index (AQI) in Managua, the capital of Nicaragua, is measured at a score of 26. According to the US EPA health standard, this air quality rating is categorized as Good. The current atmosphere in Managua is influenced by a PM2.5 (fine particulate matter) concentration of 4.7 µg/m³ and PM10 levels recorded at 9.7 µg/m³. Monitoring of gaseous pollutants shows Nitrogen Dioxide (NO2) at 1.4 µg/m³.

Beyond the primary urban hubs, atmospheric conditions and smog levels fluctuate across Nicaragua 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 León, Masaya, Chinandega, Matagalpa and Estelí. 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: Nicaragua Right Now

Across 6 monitored cities in Nicaragua, live air quality currently ranges from a low of 23 AQI in Estelí (the cleanest air right now) to a high of 55 AQI in Chinandega (the most polluted). By US EPA health band, the nationwide distribution stands at 5 Good, 1 Moderate. The average fine-particulate (PM2.5) concentration across these cities is 6.0 µg/m³ — approximately 1.2 times the World Health Organization (WHO) annual air quality guideline of 5 µg/m³.

* Air Quality Index (AQI) data for Nicaragua 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 Nicaragua

The median reading across 6 monitored cities is 27.5 AQI. The national spread is 32 points, from 23 in Estelí to 55 in Chinandega. Average PM2.5 is 6.0 µg/m³ (1.2× 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 Nicaragua — FAQ

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

What is the current air quality in Nicaragua?

Live AQI readings for 6 city(ies) across Nicaragua are listed above on the US EPA 0-500 scale.

Where does Nicaragua's AQI data come from?

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

What is a healthy AQI value in Nicaragua?

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 Nicaragua?

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 Nicaragua.
