Ho Chi Minh City, Vietnam
Air quality in Ho Chi Minh City is forecast to reach US AQI 126 (Unhealthy for Sensitive Groups), peaking around 19:00 local time. People with asthma, heart or lung conditions, children and older adults should limit outdoor exertion. At that hour the model has PM2.5 36.2 ug/m3 and PM10 36.6 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.
