Shanghai's extreme heat did not top 50 degrees Celsius but climbed above 40 and triggered this year's fourth red heatwave alert on Friday afternoon, the highest alert in the three-tier system.
Some netizens said the temperature shown on their mobile phones topped 50 degrees.
However, the highest temperature the benchmark Xujiahui Weather Station measured was 40.2 degrees, according to the city's meteorological authorities.
Weather apps in smartphones do not show the actual observation weather data, but use estimate data collected by other methods, meaning the data was not accurate, the authorities explained.
Today marked this year's 32nd high-temperature day with the mercury rising above 35 degrees, and the fourth time the city has roasted in over 40-degree heat.
This latest heatwave is due to strong subtropical high pressure, which is plaguing most of southern China, combined with a lack of cold air from the north, according to meteorological authorities.
The scorching weather is predicted to linger in the city for the next 10 days, with highs close to 40 degrees and lows near 30.
Affected by the upper shortwave trough, the city is expected to see severe convection weather on Saturday with lightning and heavy rain, high temperatures of 38 or 39 degrees and lows of 29, forecasters said.
Parts of the city may experience hails and strong winds tomorrow.
