Air Quality Index (AQI) in Haiti 🇭🇹

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

Currently, the Air Quality Index (AQI) in Port-au-Prince, the capital of Haiti, is measured at a score of 64. According to the US EPA health standard, this air quality rating is categorized as Moderate. The current atmosphere in Port-au-Prince is influenced by a PM2.5 (fine particulate matter) concentration of 16.1 µg/m³ and PM10 levels recorded at 18.7 µg/m³. Monitoring of gaseous pollutants shows Nitrogen Dioxide (NO2) at 5.2 µg/m³.

Beyond the primary urban hubs, atmospheric conditions and smog levels fluctuate across Haiti 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 Carrefour, Delmas 73, Port-de-Paix, Pétionville and Croix-des-Bouquets. 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: Haiti Right Now

Across 15 monitored cities in Haiti, live air quality currently ranges from a low of 32 AQI in Port-de-Paix (the cleanest air right now) to a high of 140 AQI in Jacmel (the most polluted). By US EPA health band, the nationwide distribution stands at 3 Good, 10 Moderate, 2 Unhealthy for Sensitive Groups. The average fine-particulate (PM2.5) concentration across these cities is 18.1 µg/m³ — approximately 3.6 times the World Health Organization (WHO) annual air quality guideline of 5 µg/m³.

Haiti Air Quality: Major Cities Index

* Air Quality Index (AQI) data for Haiti 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 Haiti

The median reading across 15 monitored cities is 64 AQI. The national spread is 108 points, from 32 in Port-de-Paix to 140 in Jacmel. Average PM2.5 is 18.1 µg/m³ (3.6× 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 Haiti — FAQ

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

What is the current air quality in Haiti?

Live AQI readings for 15 city(ies) across Haiti are listed above on the US EPA 0-500 scale.

Where does Haiti's AQI data come from?

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

What is a healthy AQI value in Haiti?

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 Haiti?

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 Haiti.
