Changsha

Best Time


It is not easy to find the best time to visit Changsha. Being that the spring is very rainy and with little sunshine, you can choose autumn, especially from late September to early November, since it is the least rainy period of the year, and it is generally mild or pleasantly warm. It must be said that in autumn, the arrival of the remains of typhoons cannot be excluded, although the sea, from which they come, is far away.
