Chushu, or the End of Heat, is the 14th of China’s 24 Solar Terms and the second term in autumn. It usually falls around August 22–24, when the Sun reaches 150° celestial longitude. The name marks a traditional seasonal shift—not a guarantee that hot weather ends everywhere on that date.

What is Chushu, or the End of Heat?

Chushu (处暑) is commonly translated as “End of Heat.” In the traditional calendar, it signals that summer heat is beginning to retreat as autumn advances. The Hong Kong Observatory describes the 24 Solar Terms as a time-knowledge system developed through observation of the Sun’s movement, seasonal progression and changes in nature.

Chushu is the 14th term in the sequence and the second of the six terms associated with autumn. Its place in the calendar describes a seasonal stage; it is not a weather forecast for every location.

When does the End of Heat solar term occur?

Chushu arrives when the Sun reaches 150° celestial longitude. In the Gregorian calendar, that point generally falls around August 22–24. The exact civil date can vary by year and time zone, so the date range is a guide rather than a fixed annual date. Visit Beijing: 24 Solar Terms|End of Heat Hong Kong Observatory: 24 Solar Terms

For 2026, the Hunan Provincial Government identifies August 23 as the beginning of Chushu. That is the date for that year, not a date that repeats every year. Hunan Provincial Government: 24 Solar Terms—Chushu

Does Chushu mean hot weather is over?

No. The term marks the traditional calendar’s transition away from summer heat, but local conditions do not change uniformly. Heat can linger after Chushu; Beijing’s seasonal account describes an “autumnal tiger” period, while Hunan’s 2026 account notes that it could still be hot when the term began. Use a local forecast to plan for actual temperatures rather than relying on the solar-term date. Visit Beijing: 24 Solar Terms|End of Heat Hunan Provincial Government: 24 Solar Terms—Chushu

What customs and seasonal activities are associated with Chushu?

Accounts of Chushu describe different local practices rather than one custom observed by everyone across China. Examples reported in Beijing material include:

  • Eating duck and preparing herbal tea.
  • Watching the changing shapes of clouds, sometimes described as “artful clouds.”
  • Floating river lanterns. A separate Beijing account connects lanterns with Zhongyuan observances and remembrance and wishes for blessings.
  • Taking part in harvest work as crops mature and the agricultural season turns.

These are regional examples, not evidence that the practices are universal or equally widespread. Hunan’s 2026 account likewise describes Chushu as a busy harvest season, while Beijing’s overview notes farmers’ crop work.
