It is reported that Xiamen will have rainfall from April 15 to 17 and cloudy days afterwards. The temperature keeps around 20C, not cold at all. You may found that some locals already wear cool summer clothes.

Dear Ms. Sophie,

That's meant i no need to bring any sweater during 15/4 - 20/4/2010? just need to wear t-shirt & pants will do? can it be a short pants as well?

Of course no need to take sweater. In the first several days, you may have to wear long jeans and long-sleeved shirt due to the rainfall. After April 18, short pants will be ok. Anyway, the recent weather is changeful, so please pay attention to the up-to-time weather forecast.
