Introduction to Xian Climate
Xian is located in the southern part of the Guan Zhong Plain in Shaanxi province. It has a continental monsoon climate with four distinct seasons. It is hot and wet in summer, dry and occasionally snowy in winter and prone to extended spells of rain in spring and autumn.
Temperatures in spring is subject to fluctuation. The average temperature in March is 8 C (46 F), rising to 14 C (57 F) in April and 19 C (66 F) in May. Sweaters or a thick coat is recommended in early spring, and long-sleeved shirts or T-shirts with light jackets will do in middle spring. By late spring, you can break out your summer clothes. Gentle breezes and warm sunshine make it a good time of year for outdoor activities like climbing Lishan Mountain or enjoying cherry blossoms at Qinglong Temple.
Summer in the area is both hot and humid. Xian is one of the major 'stove' cities in China with the hottest month of the year. The heat is oppressive but is tempered somewhat by an average of eight to eleven rainy days each month. Indoor attractions like the Museum of Qin Terracotta Warriors and Horses or the Shaanxi History Museum are good choices at this time.
The area experiences a fair amount of precipitation during the months of September and October. The weather can also be overcast and a bit cool. Long-sleeved shirts or a sweater and light coat are appropriate. The City Wall Marathon, a fixture since 1993, is held annually in early November.
Winter weather here runs from November to February when it is dry and cold with a little snow. The coldest month is January with an average temperature of 0 C (32 F). Remember to bring warm clothing and drink enough water to prevent dehydration. A major winter highlight is the annual Lantern Festival usually held on Xian City Wall in middle January or February.
