Is this the right time to go to Beidaihe? What is the weather like in Qinhuangdao? Will it be cold by the sea?

Personally, I think this is the best time to come to Beidaihe, because the weather in Beidaihe is neither too hot nor too cold, which is just suitable for traveling. At this time, ultraviolet rays are not too strong, which is most suitable for travel. The weather in Qinhuangdao is not bad now. Ultraviolet rays are not strong during the day, and it will not be very cold at night. The daytime temperature is about 25 degrees, which is suitable for short sleeves, and it is a little cold in the morning and evening, which is suitable for long-sleeved shirts.
