September weather forecast
China

September brings noticeable changes to China's weather patterns. As the country transitions into autumn, temperatures begin to fall, and the monsoonal rains gradually decrease, making it one of the most pleasant months to visit.

In southern China, including Guangzhou, the intense heat of the summer begins to ease. Temperatures typically fluctuate between 24°C (75.2°F) and 31°C (87.8°F), providing a welcome relief from the previous months' extreme heat. In the high-altitude Yunnan Province, the weather remains relatively temperate, with readings varying between 14°C (57.2°F) and 24°C (75.2°F).

September also marks a significant decrease in monsoonal rainfall. While the southeastern regions still receive substantial amounts of rain, the precipitation levels across the rest of the country continue to decline compared to the peak monsoon months.

The high-altitude areas, such as Mount Everest, maintain their sub-zero temperatures, ranging from -16.9°C (1.6°F) to -27.1°C (-16.8°F). However, snowfall is less frequent compared to the winter months, making it a suitable time for high-altitude treks.
