Heat wave forecast to be brief

Data suggests that Shanghai is getting hotter. Last year, the city experienced a high of 40.9 C on July 21 during a heat wave that lasted for 11 days, the longest in the city in 145 years. That high broke the previous record of 40.8 C set in 2013.

To better cope with such extreme weather, local government has come up with measures to protect the vulnerable, especially those working outdoors.
