Air Quality Index (AQI)
The Air Quality Index (AQI) tells you how clean or polluted your outdoor air is and the associated health effects that may be of concern.
www.airnow.govI don’t have live access to current AQI data in this moment, but I can point you to reliable sources for the latest air quality index (AQI) updates and provide guidance on how to interpret them.
Where to check latest AQI
- AirNow (airnow.gov): U.S. national and local AQI, nowcasts, and forecasts. Useful for real-time conditions and health recommendations.
- WAQI (waqi.info): Real-time air quality map with AQI values for many countries, including PM2.5/PM10 breakdowns.
- Your national or regional environmental agency: For France, Météo-France and official French environmental agencies often provide current air quality alerts and forecasts for cities including Marseille.
- Local weather or news outlets: They frequently publish today’s AQI and any health advisories, especially during pollution events.
How to interpret AQI (general guidance)
- 0-50 (Good): Air quality is considered satisfactory, and little or no risk for most people.
- 51-100 (Moderate): Acceptable, but some pollutants may affect sensitive groups.
- 101-150 (Unhealthy for sensitive groups): People with respiratory or heart conditions, children, and older adults may experience health effects.
- 151-200 (Unhealthy): Everyone may begin to experience health effects; sensitive groups may experience more serious effects.
- 201-300 (Very Unhealthy): Health alert for everyone; outdoor activities should be limited.
- 300+ (Hazardous): Health warnings of emergency conditions; avoid outdoor activity.
What I can do next
- If you share a specific city or neighborhood in Marseille or nearby, I can tailor guidance on when to expect higher exposure and typical local sources of pollution.
- If you want, I can fetch and summarize the latest reported AQI from public sources you prefer, then provide a brief, plain-language interpretation and any recommended precautions for today.
