In China the climate varies radically, so a decision about the best time to visit should be based on the regions you plan to tour and the kind of weather you enjoy. Autumn is normally the most comfortable season of the year
(September to early October). During that period, temperatures are reasonable throughout China (about 10 till 22 degrees Celsius, 50-72 degrees Fahrenheit) with a limited amount of rain. Spring roughly has the same average temperatures as autumn.
