Taiyuan has a temperate inland climate, that is somewhat offset by occasional monsoon weather. The annual average temperature is 9.3 degrees C., with dry and cold winters and sweltering dry summers.

Spring and summer are often blindingly bright, so sunglasses and a hat are recommended to fight radiation. Since Taiyuan is also a mining city, it is also worth taking along something to clean your face!

Generally speaking the best time to visit is between May and October, if you do not mind the heat.
