Several regions of China including the major southwestern city of Chongqing baked in temperatures exceeding 40° Celsius today, while the country's national observatory continued its red alert for high temperatures.

In Zhejiang, home to many factories and exporters, a meteorological official said that the eastern province has broken its previous record for high-temperature days this year, with 31 days above 35° and 16 days above 38°.

Along with Chongqing, which saw temperatures up to 42.1° weather on Saturday, Hubei, Hunan, Shandong, Anhui, Xinjiang, Jiangxi and Fujian were among the provinces and regions where temperatures exceeded 35°.

A thunderstorm appeared to have helped spare Shanghai from breaking its 40.9° record today, though residents of the commercial hub of 25 million still expressed fatigue from the ongoing heatwave.

"It's like being in a steamer, it's really hot," said 70-year-old resident Shen Fengming.

"Even if you don't walk around outside, you'll still end up sweating."

Container port worker Huang Yi, 45, concurred, saying: "I went to our port and walked around.

"It was just an hour, but my clothes and pants were all wet. Compared to years before, the temperature this year is particularly high."

Last week China's weather bureau warned that the country's average ground temperatures have risen much more quickly than the global average over the past 70 years and will remain "significantly higher" in the future as the challenges of climate change mount.
