The average annual temperature in Nanjing is about 15 
Verdant Ming Xiaoling Mausoleum 
C (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.
The short and comfortable autumn time from October to mid-November is the best travel period for the city. Unlike other southern cities in China, in December, it sometimes snows in the city. If fortunately, (may not be fortunate for some people), you will have an opportunity to appreciate the enthralling white snow world of Nanjing. In the coldest month - January, the temperature could be as low as -7C (19F).

Hello! I'm planning to study abroad in Nanjing, China for the fall semester (late august-late january) and I have no idea what to pack! Can anyone suggest something please?

Ms.Christine replied:
Of course, should take your clothes of summer, fall and winter. And, your computer and camera. Maybe you should purchase a new cell phone, at least a loca SIM card in China. For lady, take some cosmetics for you from USA is smart~ Actually, most of the life necessities could be purchased in Nanjing. Hope this helps!
