When will the rainy weather in Guangdong end?

The humid weather in Guangdong will disappear after the end of April.

The wet weather in Guangdong is generally in March every year, and March is also a frequent period of returning to Nantian. The main reason is that after the cold air leaves in winter, the warm and humid air flow strikes back, which leads to the increase of temperature and humidity in the air. When furniture, floor, glass and other surfaces encounter warm and humid airflow, small water droplets will be produced. It usually lasts for 3 to 5 days. If there is no warm current, it will last for a month. After the end of April, the wet weather will disappear completely with the Qingming rainy festival.

Usually supplemented by cold air, it disappears immediately. If it stays warm for 3-5 days, it can last for more than half a month. When "Returning to the South" appeared, the air humidity was close to saturation, and the walls and even the ground would "bubble". There were wet scenes everywhere, and the air seemed to be able to wring out water. Dense fog is the most distinctive appearance of Huannantian, which can reduce visibility to 50 meters when the phenomenon is serious.

The main reasons for the formation of huinantian

In spring, water will come out from the walls and floors in the southern sky, which is actually very similar to the principle of sea fog. Warm and humid ocean air flows from the warmer sea surface to the colder sea surface, and the water vapor in the air condenses into water droplets and accumulates in the air to form fog. If the temperature difference between the sea surface through which the airflow passes is large, there is a greater chance of forming fog.

Similarly, due to the cold weather in winter, the walls and floors are very cold inside and outside. If warm and humid air flows through the walls and floors at this time, the water in the air will condense into water droplets and adhere to the walls and floors, just as water seeps from the walls and floors. In summer, even if there is humid ocean airflow, the walls and floors are not cold enough inside and outside, and the walls and floors will not get out of water.
