Risshu

Hot day continues everyday.
However, on calendar today it is the day of Risshu.
It is the day when signs of autumn will start to appear.
[ The summer heat of the year ]
It was written in the weather forecast of the Japan Meteorological Agency announced at 5 o'clock this morning that today's maximum temperature in Nara City will be 33 degrees Celsius.
Yesterday's maximum temperature was 36.8 degrees Celsius, so it seems to be lower than that.
I am a little relieved.
Expression such as "the heat at risk of life" is said on television every day.
It is an expression that came to be used frequently this year.
Summer in Japan is hot.
However, the heat of this year is abnormal.
The highest temperature in Nara City last month was 38.1 degrees Celsius.
In addition, the average of maximum daily temperatures in Nara city last month was 34.2 degrees Celsius.
The maximum temperature and the average of maximum daily temperatures in Nara city in July from 1990 to 2018 is as follows.

The maximum temperature and the average of maximum daily temperatures in Nara city

These show that this year is much hotter than usual.
These are using data of Japan Meteorological Agency.
[ Risshu ]
It is said that autumn is approaching on the calendar in such a hot summer this year.
Today, August 7th is the day of Risshu.
Risshu is the day when signs of autumn begin to appear.
Many people can not believe it at all from the forecast of the highest temperature today.
Risshu is one of nijushi-sekki.
Spring, summer, autumn and winter is a season in which one year was divided into four, but nijushi-sekki is a season when one year was divided into 24.
In addition, the risshu also means the period until the shosho of the next sekki.
We have seasons to divide the year into 72.
We call it seventy-two ko.
Today is "Suzukaze itaru" in seventy-two@ko.
"Suzukaze itaru" means a cool wind blows.
[ zansho mimai and shochu mimai ]
Today is risshu, although it will continue for a while on a hot day.
We sometimes write letters to those who have not met for a while.
We will send a letter of "zansho mimai(late-summer greeting card)" at that time after the risshu.
We will send a letter of "shochu mimai(summer greeting card)" before the risshu.
[Autumn signs]
Yesterday was very hot all day and I never felt a sign of autumn.
Today is risshu, so I 'll try to find the sign of autumn.
If I can find it it will make me feel comfortable.
