Tip for Suzhou Weather
Best time to visit Suzhou
The best time to travel to Suzhou is April to October, when the trees and flowers of this garden city are green and in full bloom
 
Spring and Autumn are the peak tourist seasons, and are very comfortable. Summer is a peak tourist season too, but is hot and oppressive, as the humidity makes it almost impossible for people not used to the environment to breathe properly. Clothes tend to get fairly wet after just a few minutes of walking.
 
The city has some Typhoon spells during the year, none of which in recent years have caused significant damage.
 
Try to Avoid domestic travel seasons
Try to plan your Suzhou tour by avoiding the peak holidays. Because of the Chinese tourists, those attractions become more crowded in these periods.
 
The most crowded seasons in China are Chinese Spring Festival (usually in late Jan or early Feb.), International Labor Day (May 01 to 03) and National Day (Oct 01-07). Spring Festival and the National Day golden week are the most crowded time for traveling.
