Vietnam air quality today The AQI right now, city by city

Right now the 114 cities Airleaf measures in Vietnam average AQI 59 (moderate). The worst air is in Thuận Thanh, at AQI 132, and the cleanest in Huế, at AQI 33. At ground stations alone, which measure rather than estimate, the average is AQI 92 across 20 cities. 8% of the 114 measured cities are over AQI 100 today, where the air stops being fine for sensitive groups, and 33% have Good air.

Thuận Thanh, at AQI 132 (Unhealthy for sensitive groups) on the US EPA index. Sensitive groups should limit long or intense outdoor activity.

Huế, at AQI 33 (Good). Both lists rank current readings, from ground stations wherever Vietnam has at least three cities with one.

It depends on the city. 38 cities are Good, 67 cities are Moderate, 9 cities are Unhealthy for sensitive groups. At the national average of AQI 59: Unusually sensitive people should consider limiting long outdoor exertion.

About 3.85 million ha from 2001 to 2025, 23% of the forest it had in 2000, from the University of Maryland's yearly satellite maps of forest loss. 1.41 million ha of it was cleared for good, for farms, mines or towns.

Thị Trấn Thuận Châu, with 82.6% tree cover within 2 km of its center, measured from Sentinel-2 satellite images.

Each city's reading is the US EPA air quality index, from ground monitoring stations where one has reported recently nearby, and from the CAMS atmospheric model elsewhere; each city's report says which. Tree cover is measured over the same 2 km radius in every city, so the cities compare like for like.
