Weather and Climate in Xian

Xi'an, located roughly in the geographical center of Mainland China, has a continental monsoon climate with four distinctive seasons. It is hot and wet in summer, dry and occasionally snowy in winter, and prone to extended spells of rain in autumn.

Xi'an weather is mild with four distinct seasons - a warm but variable spring, a torrid summer, a cool autumn, and a dry and chilly winter. The highest temperature occurs in July, 35 – 40  C (95 – 104  F); while the coldest month is January, with the temperature low to -10 – -5  C (14 – 23  F). There is a moderate rainfall caused by frequent summer storms and a succession of overcast and rainy days in autumn.

For the best time to visit Xi’an

Xi'an climate in spring is usually warm and pleasant, and March to May is the best time of a year to pay a visit. Early autumn running through September and October is also a good season for travel.

Spring (Mar. - May) 

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. A sweater or a thick coat is recommended in early spring in March, and a long-sleeved shirt or a T-shirt with a light jacket will do in April. By late spring in May, you can bring your summer clothes. Gentle breeze and warm sunshine make spring a good time for outdoor activities like climbing the Mt. Huashan or enjoying the cherry blossom at the Qinglong Temple. 

Summer (Jun. - Aug.)

Summer from June to August is hot and a little moister than spring. Xi'an is one of the major 'stove cities' in China, with July as its hottest month of the year. The heat is oppressive but is tempered somewhat by an average of 10 rainy days each month. Indoor attractions like the Terracotta Army Museum or Shaanxi History Museum are good choices in this season. 

Autumn (Sep. - Nov.)

The city experiences a fair amount of precipitation during September and October. The weather is generally overcast and cool.  A long-sleeved shirt or a sweater and light coat are appropriate. The City Wall Marathon, a fixture since 1993, is held annually in early November. 

Winter (Dec. - Feb.)  

Winter weather in Xi'an lasts from mid-November to February the next year. It is dry and cold with a little snow. The coldest time is January with an average temperature of 0 C (32 F), and the lowest temperature sometimes drops below  -5 C (23 F). Remember to bring warm clothing and drink enough water to prevent dehydration. A major winter highlight is the annual lantern fair held on the City Wall during the Chinese New Year in January or February.
