Heat wave forecast to be brief

Zhu Jiehua, chief meteorologist at the Shanghai Meteorological Bureau, said that while high temperatures of over 37 C are not as common in June as in July or August in Shanghai, it is not rare for the city to experience such a heat wave in the season. Shanghai also experienced several days of sweltering heat around this time in 2009 and 2011, Zhu added.

It is, however, still difficult to tell whether the city will have another extremely hot summer this year, Zhu said.
