Note: The standard for entering summer is in accordance with the provisions of the meteorological industry standard of the People's Republic of China "Division of Climate Seasons". The 5-day moving average temperature series is calculated based on the current year's temperature series to form a moving average temperature series. When the moving average temperature series is greater than or equal to 22 ℃ for 5 consecutive days, the first date in the corresponding year's temperature series that is greater than or equal to 22 ℃ is taken as the start date of summer.

The newly issued Division of Climatic Seasons in February 2023 stipulates that if the starting date of the initial judgment is more than 30 days (inclusive) earlier than the normal year, the starting date shall be judged twice/more times.
