Too severe lingering summer heat Dangerous heat exceeding body temperature
August 21, 2023 11:57
Today, the 21st, the sky is wide open, and the temperature is rising rapidly in the morning. In some places, the heat is as hot as body temperature, and it is possible that the city center will experience the 22nd heat wave this year. The temperature will drop slightly tomorrow on the 22nd and the day after tomorrow on the 23rd, but the heat will continue into the end of August.
Dangerous heat that exceeds body temperature from the morning of the 21st today
Today, the 21st, the area around Honshu is covered with high pressure.
The sunshine is reaching a wide area from Okinawa, Kyushu to Hokkaido, and the temperature is rising rapidly from the morning.
By 11:30 a.m., the highest temperature was 37.1°C in Akihaku, Niigata City.
Hirakata City, Osaka Prefecture has a temperature of 36.5℃, Tsujido, Fujisawa City, Kanagawa Prefecture has a temperature of 35.4℃, and Kyoto, Hiroshima, Nagoya, and Fukui also exceed 35℃.
The temperature in central Tokyo has risen to 33.0°C, and the humidity has risen to around 60%, making it a very hot and humid experience.
Too severe lingering heat Record-breaking heat continues
The temperature is still rising, and it will become even more intense after this.
From Kyushu to Tohoku, the temperature rises to around 35 degrees Celsius, with Kyoto reaching 38 degrees Celsius and Osaka and Hiroshima reaching 37 degrees Celsius.
The number of sites with extremely hot days is expected to increase from yesterday’s 20th, to more than 200 sites, which is about 20% of the number of AMeDAS sites. (182 points on yesterday 20th)
If today’s 21st is another extremely hot day in central Tokyo, it will be the 22nd hottest day of the year, far surpassing last year’s annual record of 16 hottest days.
The cities of Kanazawa and Sendai are also setting new records for the number of extremely hot days in a year.
If you don’t take measures against heatstroke, the heat can be life-threatening.
Please try to prevent heatstroke by refraining from going out during the hottest hours of the day or keeping it short.
Sweltering heat that can be endured even if it is too hot
The 23rd is the 24th solar term “Shosho”. According to the calendar, the severe heat will subside a little.
Tomorrow, the 22nd, the sun will reach a wide area, and the intense heat will continue, but on the 23rd, it seems that clouds will spread more easily as moist air flows into the Pacific side of western Japan and eastern Japan. Due to the lack of sunlight, the intense heat will subside a little in some places.
However, even if the temperature drops, the humidity will rise, so it seems that some places will feel hotter than ever at night. Heat stroke measures are indispensable throughout the day.
In Hokkaido, the severe heat will not subside until around Friday. From Tohoku to Kyushu, the intense summer heat is likely to continue.
We’ve reached the end of August, but please be careful with the heat.
Be especially careful after the Obon holidays Conditions that cause heat stroke
Anyone can develop heatstroke, and there are three major conditions that cause it.
The first is “environmental conditions”. Not only is the temperature of the day high, but a sudden hot day and a heat wave are also dangerous. Weather conditions such as high humidity, low winds, and strong sunlight can also cause heatstroke. It is necessary to be especially careful of heat stroke in environments such as closed rooms and places without air conditioning.
The second is “physical conditions”. Elderly people, infants, and people with physical disabilities should be especially careful of those around them. People who are obese or have pre-existing medical conditions (such as diabetes, heart disease, or mental illness) are also at increased risk of heat stroke. If you are malnourished or dehydrated, you may not be able to efficiently release the heat trapped in your body. Please be aware that even poor health such as a hangover or lack of sleep can make you more susceptible to heatstroke.
The third is the “behavioral condition”. Vigorous exercise or unfamiliar exercise will generate heat in your body, and if that heat remains trapped inside your body, you are more likely to get heatstroke. Please be careful, as long hours of outdoor work and situations where it is difficult to hydrate can also cause heatstroke.
After the Obon holidays, the number of people suffering from heat stroke is especially likely to increase. Please avoid the heat as much as possible.
