Chinese city still officially in summer as 30-year heat record broken

Temperatures in Guangzhou fail to drop below level that meteorological service uses to mark change in season

One of China's biggest cities is still officially in summer, despite it being mid-November, as temperatures have failed to drop below the threshold considered necessary to mark the change in season.

This week, Guangzhou, a hot and humid city of nearly 19 million people in southern China's Guangdong province, broke a three-decade heat record, according to the local meteorological service. As of Wednesday the city had experienced 235 summer days, beating 1994's 234-day season.
