I want to take my 5-year-old son to Huludao on May Day. Is it cold?

My home belongs to Huludao. . You can basically wear a coat on May Day, but you should pay attention to the strong wind because it is a coastal city. . You'd better wear sunglasses. It is windy to go there. . We have the ancient city of Xingcheng, which is worth visiting and soaking in a hot spring. . It's good to go to Chrysanthemum Island. . There is also a gourd mountain.
