What's the weather like in Qinhuangdao now? What thickness of clothes is better to wear?

I am from Qinhuangdao, and now I am in Qinhuangdao. The weather in Qinhuangdao is rather strange now. I wore a cotton-padded jacket every day a few days ago. It's still hot at noon today, and it will be cooler in the morning and evening. Last May, I just wore a thin coat with half sleeves inside. This year, I'm afraid it will be difficult. You can wear a thin cotton-padded jacket with a long-sleeved T-shirt inside. Anyway, it's hot and there's a way to undress. . .
