When will the south wind in Guangdong end?

First, what does southerly day mean? Southerly wind usually refers to the phenomenon that the temperature starts to rise and the humidity starts to rise every spring, which is the name of a weather phenomenon in southern China. 2. When is the southerly day in 2022 and how long does it last? In 2022, southerly days often appear in the season alternating between February and March, and generally end in April. Generally, southerly days can last for 3-5 days. Generally, if there is cold air to make up for it, the southerly wind will disappear immediately. If you keep warm, it can last for 3-5 days. Can grow for more than half a month. If you want to get rid of this kind of weather completely, every year is after Tomb-Sweeping Day, because there is a lot of Mao Mao rain in Tomb-Sweeping Day every year, and spring ploughing after the holiday is always like this, usually in April 15, and then you can get rid of this continuous weather.

3. Should I open the window or close it on a southerly day? It's best to close the windows on a southerly day, otherwise the humid air outside will enter the room, especially the windows facing south. This can prevent the invasion of humid air to a certain extent and maintain a certain humidity in the space. In addition, the humidity is the most serious in the morning and evening, because the temperature is relatively low and the humidity is relatively heavy. If you open the window at this time, it will let the humid air in. But if the weather turns cold or the north wind blows, you can open the window to breathe fresh air, and the moisture in the house can be removed in time, so please remember to pay attention to the weather forecast.

Professional doctors suggest that although doors and windows need to be closed in the south wind to prevent moisture from invading, at least half an hour should be set aside for ventilation in a day, and then doors and windows should be closed after ventilation, and then other measures should be taken to remove indoor water vapor, such as wiping water drops with a dry rag and turning on the air conditioner for dehumidification. The most taboo is dehumidification. The doors and windows at home are closed all day, and the air conditioner is on all day, which is very easy to induce air-conditioning diseases.
