How's the weather in Taipei for April 2013? Rainy? Or Sunny? Need to prepare any gears?

It is cloudy in most cases. Its temperature will range from 15C to around 30C between daytime and nights, so the big temperature gap should be paid much attention. You can take along both long-sleeved and short-sleeved shirts as well as a light coat. As it is starting to come to the plum rainy season, the rainfall is relatively frequent, but not dense. Anyway, rainy gear is suggested to be prepared.
