To tell you exactly, there are roughly two kinds of winters in Beihai. One is that there is no north wind and rain on sunny days, and the other is that there is north wind or rain on cloudy days. If it doesn't rain or the north wind blows, the temperature is generally above 20 degrees. This kind of weather is not cold. For example, we wear short sleeves during the Spring Festival. But if the north wind blows and it rains a little, the temperature may reach about six or seven degrees. At that time, it was the coldest time in the North Sea. Generally, you should wear a cotton-padded jacket or down jacket, and your hands and feet will obviously feel frozen.
It should be noted here that the lowest temperature in the North Sea in winter is above five or six degrees above zero. If it is in the northeast, we can all wear short sleeves and play basketball in the outdoor basketball court. In Beihai, everyone is reluctant to move, mainly because Beihai is in the south, and the north wind can't blow indoor heating, and some are just air conditioners in their own homes. So I feel cold. So if you are in a neighboring province of Guangxi, don't worry. If you are from the north, you only need to bring a down jacket, hehe.
