In 2023, when will it enter Mei and when will it leave Mei?

Mei entered in mid-June, 2023, and Mei went out in early July.

There is no provision for the entry and exit time of plum blossoms in different regions. For example, in Shanghai a few years ago, before June 17 if there is no time, it is expected to enter the plum blossom in June 10 this year. There is also Zhejiang, which entered Mei on May 29 last year, but the expected time this year is June 10, and last year was the earliest time in 20 years.

In the middle and lower reaches of the Yangtze River in China, the rainy season is from mid-June to early July every year, which lasts for 30-40 days, mostly between the two solar terms of mango and summer. The rainy season is characterized by high temperature and many times, and the coastal areas of South China will also be hit by typhoons, and the weather and humidity will increase, so it is called "mildew rain". But this time is when the plums in the south of the Yangtze River are ripe, which is also called "Plum Rain" or "Huang Meiyu".

The standard of plum blossom:

1, it doesn't rain for five consecutive days, and the average temperature (minimum temperature plus maximum temperature divided by 2) exceeds 30 degrees, indicating that plum blossoms are in bloom. Astronomical standard, that is, the method of combining solar terms and branches in China's ancient calendar, is a traditional calculation method in China, and the plum blossom time published in some modern desk calendars and calendars is calculated according to this standard.

2. Climate standard is to determine the approximate time of plum blossom in a certain area according to the average value of plum blossom for many years, which has certain reference value for people's life and production.

3. The weather standard has specific and detailed indicators, and local meteorological departments issue plum blossom time according to these indicators. Therefore, the plum blossom time indicated on the calendar and desk calendar can only be used as a reference.
