It's March. What is the weather like in Beidaihe these two days? Is it suitable for watching the sea? Is it too cold?

Hello, landlord, I have been in Qinhuangdao for four years, and I know more about the weather in Qinhuangdao. March is a little too early, and hotels are basically closed. Of course, it is best to go to see the sea and swim with the sea breeze around August of the summer vacation. The weather is cool and delicious, suitable for digging crabs to watch the sunrise. The weather is best in April and May. The sky is clear, and the white willow flowers in Wan Li are particularly beautiful and have a special taste.
