Air Quality Index (AQI) in France 🇫🇷

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

Currently, the Air Quality Index (AQI) in Paris, the capital of France, is measured at a score of 31. According to the US EPA health standard, this air quality rating is categorized as Good. The current atmosphere in Paris is influenced by a PM2.5 (fine particulate matter) concentration of 5.5 µg/m³ and PM10 levels recorded at 8.3 µg/m³. Monitoring of gaseous pollutants shows Nitrogen Dioxide (NO2) at 8.3 µg/m³.

Beyond the primary urban hubs, atmospheric conditions and smog levels fluctuate across France 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 Marseille, Lyon, Toulouse, Nice and Nantes. 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: France Right Now

Across 49 monitored cities in France, live air quality currently ranges from a low of 15 AQI in Poitiers (the cleanest air right now) to a high of 44 AQI in Nice (the most polluted). By US EPA health band, the nationwide distribution stands at 49 Good. The average fine-particulate (PM2.5) concentration across these cities is 5.3 µg/m³ — approximately 1.1 times the World Health Organization (WHO) annual air quality guideline of 5 µg/m³.

Air Quality in France — FAQ

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

What is the current air quality in France?

Live AQI readings for 49 city(ies) across France are listed above on the US EPA 0-500 scale.

Where does France's AQI data come from?

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

What is a healthy AQI value in France?

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 France?

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 France.
