May I know the weather during 15 - 22 de 2013 for Xiamen, wuyishan ?

For the Wuyi Mountain, the average temperature in Dec is around 10 to 20C and it is a little bit cold in the mornings and at nights. The coat and T-shirts are enough. It may be windy at nights, so you may need some clothes to prevent the wind.
XM has the similar temperature, but the wind may not be so heavy.

Thanks for your advise.
