Hi, I'm planning to visit xian end of January 2010. will it be too cold? any flight route suggestion from Malaysia to Xian? via Beijing or via Guangzhou will be nearer to Xian? will it be easy for me to get muslim food there?
Nov. 7,2009 04:42
Mr.Shan replied:
Yes, it is just the cold winter in Xi'an during Jan. So, please take your warm clothes, such as down jacket. Currently, there is no direct flight from Malaysia to Xi'an. So, you have to transfer at Beijing or Guangzhou. Although Beijing is much closer to Xi'an, both of the Beijing Airport and Guangzhou Airport supplies frequent flights to Xi'an everyday. So, you should consider an economical international flight to Beijing or Guangzhou from Malaysia.

We are planning to travel to Xian in early February 2010. I expect it to be cold at that time, but not sure whether the weather will allow us to spend one or two days in Hua Shan and take the cable car up and down hill. Any advice?
Nov. 4,2009 04:25
Ms.Jane replied:
Actually, it is not suggested that you visit Huashan Mountain in chilly winter. If you insist, please ensure that you will do preparation well and learn the mountains (route, transportation) in advance. During some dangerous time, the mountain may be close to public.

Ms.Rebecca(Australia) replied:
Thanks Jane. That's good advice. We may have to be flexible -- depend on the weather once we arrive at Xian.

My wife and I are planning to go Xian from 8th Dec to 24th Dec this year. We understand that the temperature then is expected to be around 5-7 degree Celsius. It does not appear to be a pleasant time does it?
Sep. 6,2009 04:08
Mr.cindy(cn) replied:
Hi, i think it is ok. Xian is not so cold as before. Take the warm clothes and that will be ok
Sep. 7,2009 04:25
Mr.robin(cn) replied:
It can be below 0 degree in late December, and it may snow then.
Sep. 7,2009 06:27
Ms.JANE_W(China) replied:
Hi, I think the most important thing is not about temperature but it will be very dry at that time. So please be prepared:)
But I don't think Dec. is not a pleasant time. There will be less tourists in winter. Also, you don't need to worry rainning during travel. And the whether won't impact any interest here.
So, welcome to Xi'an!

Hi, we are planning to visit xian on 7 and 8 of october.
Will it be a good period or too busy with autumn festival (we plan to visit terracotta)?
Sep. 4,2009 03:22
Mr.Shan replied:
7&8 are last two days of the National Holiday, 2009 in China. SO, there will be lots of travelers in Xi'an, especially at these tourism attractions. Take terracotta for example, you will spend 2~3 hours enjoying the terra cotta warriors and horses and then another 2~3 hours on bus. But, the weather should be comfortable during the holiday, except for rainfall.

It is confirmed that I will be in Xian for 2 weeks in 17 Sep 09. Not sure about weather condition over there eg how often it rains & temperature ?. In additional, taxi fare like and whether according to meter. please advise.
Aug. 30,2009 19:27
Mr.Zhang(China) replied:
Although it is a rainy season in September in Xi'an, it only rains about for 10 days in this month. The average temperature ranges form 16 to 25 centigrade in Sep. So you need not worry about that. Taxi fare is certainly charged by meter , about 6 yuan for a start of 5 kilo and 1.2 for per kilometer then.

I am planning to visit Xian on September 4, do you think the weather still hot in early September (as I am travelling with my parents). Thanks.
Jul. 25,2009 03:33
Mr.Shan replied:
The hottest summer will go away from early September. The early morning and late night should be cool but the daytime is warm and dry usually. Well, the city may have successive rainfall during this period. Anyway, good time for traveling.
