Riyadh, at AQI 94 (Moderate) on the US EPA index. Unusually sensitive people should consider limiting long outdoor exertion.

It depends on the city. 4 cities are Good, 16 cities are Moderate, 4 cities are Unhealthy for sensitive groups, 2 cities are Unhealthy, 1 city is Very unhealthy. At the national average of AQI 84: Unusually sensitive people should consider limiting long outdoor exertion.

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.
