The traditional Chinese lunar calendar divides the year into 24 solar terms, and End of Heat is the 14th. It arrives on August 23 this year, when the sun reaches 150° of celestial longitude.

The name "End of Heat" indicates the departure of sweltering summer. As it arrives, the scorching heat gradually subsides. Temperatures start to drop, especially in the morning and evening. The days become shorter, and the nights longer. In most parts of China, the rainy season winds down, and the air turns drier.
