During daylight hours on Thursday, temperatures in parts of Anhui, Jiangsu, Shanghai, Hubei, Hunan, Jiangxi, Zhejiang, Fujian, Sichuan, Chongqing, and Guizhou are expected to hit 37 to 39 degrees Celsius, the National Meteorological Center said.
The forecast said temperatures in some of these regions would exceed 40 degrees Celsius.
Searing heat waves started blanketing parts of China on June 13, affecting over 900 million people, according to the National Climate Center.
A total of 71 national weather stations have monitored temperatures at record highs this year, and the highest temperatures in some regions reached 44 degrees Celsius.
