September marks the beginning of autumn weather. The summer heat begins to wane, and the weather in the north becomes cooler. In South China, the hot and humid weather continues, but it is gradually replaced by cooler and drier weather by the end of this month.

September is also one of the busiest months for tourism in China. China’s top attractions are crowded with many Chinese tour groups and families.
