Following a deadly heat wave that ended July, the temperature is soaring even higher in Shanghai this week.

Temperatures climbed to 40.6 degrees C (105.1 degrees F) at Xujiahui Observatory, Shanghai's benchmark observing location, on Tuesday according to This equaled the previous all-time record high temperature.

The record would be short-lived as reported the high reached 40.8 degrees C (105.4 degrees F) on Wednesday setting a new official all-time record high.

Other temperatures across the city ranged from 39 to 41 degrees C (102-106 degrees F) Tuesday through Thursday. Another day of searing heat occurred Friday as well with temperatures climbing above 40 C once again.


Unfortunately, the extreme heat will continue through the weekend making it increasingly dangerous to anyone in the region as heat of this magnitude for several days in a row can become deadly. There may be slight relief next week although temperatures are still expected to be in the upper 30s C.

Adding to the heat, high levels of humidity will make AccuWeather RealFeel temperatures soar into well into the upper 40s C (110s C). At these levels, anyone may be at risk of heat stress or heat stroke with symptoms such as dizziness, cramping, a throbbing headache, confusion or slurred speech. If you experience any of these symptoms, get into the shade and soak yourself with water.

To prevent heat stress or stroke, try to stay out of direct sunlight, drink plenty of water, wear light-colored clothing, avoid strenuous activity and try to spend time in air-conditioned places.

In addition to adverse health effects, the extreme heat will also put stress on crops across the region. Although the core of the heat has been positioned south of the main crop growing area, impacts will still be felt. Commodity Meteorologist Dale Mohler states that "corn, rice and cotton output can be restricted due to the persistent hot weather. Soybeans, while the majority are grown north of Beijing, can also be negatively impacted."

July ended with eight consecutive days above 38 degrees C (100 degrees F) and high temperatures of at least 39 degrees C (102 degrees F) occurring four times. Dozens of people were killed during the late-July heat wave, according to the official Xinhua News Agency.

The average temperature has not been below normal in Shanghai since June 29, and temperatures are expected to remain well above normal into next week.
