I'll be in Guilin from 19-25 March 2013. How's the weather now and what clothes should I bring?

It will be cloudy, sometimes rainy at that time. The temperature range is 14C to 24C. On March, the weather forecast shows that there will be thunderstorm and on March 23, it will shower. Considering all, I suggest you take along light sweater or relatively thick long-sleeved short, jacket and your jeans. Also an umbrella may be necessary.
