White Dew is the 15th of the 24 solar terms in the Chinese lunar calendar. It begins this year on Sept.7 and ends on Sept. 22.

White Dew indicates the real beginning of cool autumn. The temperature declines gradually. Vapors in the air often condense into turns into small drops of water when it encounters cold air at night. These water drops adhere to flowers, grass and trees. When the morning comes, the sunshine makes them look crystal clear, spotless white and adorable. There is typically autumn weather during White Dews period, when wild geese begin to migrate to the south and birds start to stock food for the long winter time.

Varying by geographical location, autumn comes earlier in the west and northeast of China. During this period, Kanas in Xinjiang, Jiuzhaigou in Sichuan and the Greater Khingan Mountains in Northeastern China are entering the most beautiful season of the year. Hot summer is gone. However, it could be still warm in south China. It is different in the Yangtze River and Huaihe River valleys where it is usually humid during this period.
