www.weather.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.
