In Chengde the air is unhealthy for sensitive groups right now (approximate, US EPA scale). From 17:00 to 06:00 local time the city mean PM2.5 fell from 50.8 to 37.8 µg/m³.

Light wind (0 m/s) in the evening or at night, as the air cools, possibly traps particles near the ground (a temperature inversion). Cold weather (-3°C) possibly means more heating, a common source of particles.

Weather now: clear, -3°C, wind 0 m/s, humidity 93%. No major change in the wind is expected in the coming hours. By 17:00 the temperature will be about 5°C.
