What's the weather like in Shangri-La in March?

It's cold in March, the difference between the beginning and the end of the month is not very big, the grass is dead and the scenery is not very good. I suggest you go in July and August. On August 1 2006, I went to Bitahai and saw amazing scenery, but not at other times. There is a big temperature difference between day and night, so you should prepare clothes if you want to go.
