Hanoi, Vietnam
Air quality in Hanoi is forecast to reach US AQI 160 (Unhealthy), peaking around 18:00 local time. Everyone may feel effects. Limit time outdoors and consider a mask outside. At that hour the model has PM2.5 45.6 ug/m3 and PM10 46.3 ug/m3. The US AQI is the worst sub-index across all measured pollutants, so it can be driven by ozone rather than particulates. This is a CAMS model forecast published by Open-Meteo, not a reading from a ground monitoring station, so a station near you may report a different number.
