Climate and Travel Seasons of Nanjing

Spring in Mochou Lake
Nanjing is located in the subtropical climatic zone. The average temperature during the year is 15.3°C and the annual average rainfall is 1106.5mm. The middle of June is the so-called "Mei Yu" or "wet" period so make sure you always have an umbrella with you if you travel at this time.
Nanjing is known throughout China as one of the three "furnaces of the earth" (the other two being Wuhan and Chongqing). As such, the city can get unbearably hot in the summer months. This is not helped by the fact that the city is surrounded on all sides by mountains which help to keep the heat in and stop any breeze from entering! That said, there are many pleasant areas around the city which are a welcome respite from the baking sun and the city has an unusual amount of parks and wooded hills offering shelter to visitors and residents baking in the furnace.

The summer temperatures range between 30 and 40 degrees Celsius (86 - 104 Fahrenheit), and often feel even hotter due to the high humidity.  Air-conditioners are present in nearly every home, restaurant and car. Some buses have air-conditioning while others do not.

During winter the temperature occasionally drops below 0 degrees Celsius (32 Fahrenheit), but usually it hovers around 5 degrees Celsius (41 Fahrenheit).In December it is prone to snow, and although very picturesque, temperatures do fall well below freezing. Interior heating is not standard inside apartments.  Indoor public areas such as shopping centers and restaurants are usually warmer, but they are not always heated to the extent that people should need to take their jackets off.  Layered clothing, a warm jacket, and an umbrella are appropriate during this season.

As with many other cities in the east of China, spring and autumn are the most pleasant seasons to visit, when there is blossom or greenery on the trees and the temperature allows visitors to wander the streets and surrounding hills without dripping in sweat.
