Tips for Xian Weather
What to wear
March is the beginning of the city's peak travel season.
 
There is rarely snow in March and the weather warms quickly with an average temperature of 14ºC. A sweater and a light coat are generally enough, though there may be hot days when you only need summer clothes such as a T-shirt. Flowers begin to bloom at the end of March.
 
April weather is generally warm and occasionally very warm. A shirt with a light coat is enough for the beginning of the month, but as it grows very warm at the end of April you may be able to dispense with the jacket.  April is the best month to see flowers in Xi'an
 
May: It is hot. Summer clothes are recommended with an extra layer for evenings.
