Next Monday (July 15), the official start of entering the “Midsummer” will mark the beginning of a 40-day period this year. Meanwhile, the China Meteorological Administration predicts that in the coming week, most parts of Jiangnan and South China will continue to experience sustained high temperatures, with highs ranging from 35 to 39 degrees Celsius.
According to the traditional calendar, counting from the summer solstice, the third “Geng day” signifies the start of the early Midsummer. This year, the Midsummer begins on July 15, lasting for a total of 40 days.
The “Tianyan News” reported that since the beginning of this century, only the years 2004, 2006, 2008, 2010, 2012, and 2014 have had Midsummers lasting for 30 days, while the other 18 years all had Midsummers lasting for 40 days. From 2015 to 2024, for a decade straight, Midsummers have all been 40 days in duration.
On July 13, the China Meteorological Administration announced that in the next week, most parts of Jiangnan and South China will experience sustained high temperatures, with the highest reaching between 35 and 39 degrees Celsius.
During the daytime of the 13th, regions including the eastern part of Hunan, Jiangxi, Zhejiang, Fujian, the eastern part of Guangxi, the central and northern parts of Guangdong, the eastern part of Xinjiang, the western part of Inner Mongolia, and the southern part of Shanxi will have temperatures exceeding 35 degrees Celsius. Among them, certain areas in the eastern part of Hunan, the central and southern parts of Jiangxi, the central and southern parts of Zhejiang, and the eastern part of Fujian, as well as some areas in the eastern part of Xinjiang, may see temperatures soar to 37-39 degrees Celsius.
It is expected that on the 14th, as the subtropical high-pressure system moves north, the range and intensity of the heat in the southern regions will expand and intensify, leading to prolonged high temperatures.
Furthermore, the main belt of rain from Sichuan to the middle and lower reaches of the Yangtze River, with the subtropical high-pressure system further moving westward and northward, will extend to the northeastern parts of the Huang-Huai region. Some areas in the southern part of Sichuan Basin, the northeastern part of Hubei, and the southeastern part of Anhui are expected to face heavy rainfall, while regions like Shandong, Henan, and Hebei will also experience a significant increase in rainfall.
