What is the weather like from March to May in Shanghai?

Jackie, the average temperatures in these three months are 48F, 59F and 68F, according to previous records. Generally speaking, it seldom rains because it is in dry season. I think you should bring a thin sweater, thick and thin jackets, shirts, jeans and T shirts. In March, you need to wear thick jacket and sweater. In April and May, thin jackets, shirts and T shirts are enough.
