The average annual temperature in Nanjing is about 15C (60F) and the time from mid-June to July is the rain period. Known as one of the three hottest cities in China, Nanjing's scorching summer period is to be avoided. The average ground temperature can reach 35C (95F) and the extreme highest point could reach 40C (104F) sometimes.
The city's location at the lower river valley of the Yangtze River make thing worse as nearby mountains hold the hot air in. The government has launched a tree planting campaign throughout the city hoping to ease the sweltering situation.
