While freezing temperatures are not uncommon for the time of year, the sudden change is unusual.
A few days ago, uncharacteristically warm weather saw parts of northern China post record high temperatures exceeding 30C.
Winter this year, however, could be warmer due to a moderate El Nino, Jia Xiaolong, deputy director of China's National Climate Centre, told a press conference on Friday.
El Nino is a natural climate pattern associated with warming of the ocean surface temperatures in the central and eastern Pacific.
But statistics showed that winter temperatures could fluctuate greatly during El Nino, Jia warned.
