Air Quality Index (AQI) in Colombia 🇨🇴

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

Currently, the Air Quality Index (AQI) in Bogota, the capital of Colombia, is measured at a score of 10. According to the US EPA health standard, this air quality rating is categorized as Good. The current atmosphere in Bogota is influenced by a PM2.5 (fine particulate matter) concentration of 1.8 µg/m³ and PM10 levels recorded at 1.8 µg/m³. Monitoring of gaseous pollutants shows Nitrogen Dioxide (NO2) at 3.6 µg/m³.

Beyond the primary urban hubs, atmospheric conditions and smog levels fluctuate across Colombia 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 Cali, Medellín, Barranquilla, Cartagena and Cúcuta. 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: Colombia Right Now

Across 60 monitored cities in Colombia, live air quality currently ranges from a low of 5 AQI in Popayán (the cleanest air right now) to a high of 158 AQI in Girardot City (the most polluted). By US EPA health band, the nationwide distribution stands at 45 Good, 14 Moderate, 1 Unhealthy. The average fine-particulate (PM2.5) concentration across these cities is 8.6 µg/m³ — approximately 1.7 times the World Health Organization (WHO) annual air quality guideline of 5 µg/m³.

* Air Quality Index (AQI) data for Colombia 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 Colombia

The median reading across 60 monitored cities is 38.0 AQI. The national spread is 153 points, from 5 in Popayán to 158 in Girardot City. Average PM2.5 is 8.6 µg/m³ (1.7× 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 Colombia — FAQ

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

What is the current air quality in Colombia?

Live AQI readings for 60 city(ies) across Colombia are listed above on the US EPA 0-500 scale.

Where does Colombia's AQI data come from?

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

What is a healthy AQI value in Colombia?

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 Colombia?

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 Colombia.
