What's the weather like in Weifang from June to 10?

So ... T-shirts, long sleeves, coats. The temperature won't change much. Generally/kloc-just wear a t-shirt and coat before 0/0! A pair of autumn trousers (excluding thermal underwear). It's gonna be okay. I hope you have a pleasant trip. Welcome to Weifang! Very nice place. I have been studying in Weifang for 2 years! not bad
