Is it so Hot in Summer in Japan that You can’t Sleep?
Yes, it is.
As you know, there are four seasons in Japan. In general, summer lasts for three months in June, July, and August. We change the expression of days depending on the temperature:
- The day when the high is over 25 ℃ (77 ℉) is
“夏日” (なつび, Natsu bi, Summer Day).
- The day when the high is over 30 ℃ (86 ℉) is
“真夏日” (まなつび, Manatsu bi, Hot Summer Day).
- The day when the high is over 35 ℃ (102 ℉) is
“猛暑日” (もうしょび, Mousyo bi, Extremely Hot Day)
- The day when the lowest night temperature is above 25 ℃ (77 ℉) is
“熱帯夜” (ねったいや, Nettaiya, sultry night / sweltering night)
Judging from just the temperature, it may seem that summer in Japan is not that hot. However, Japan has very high humidity. Because of this humidity, summer in Japan is muggy and unbearable. Therefore, it is not unusual to sweat a great amount like her when you wake up in the morning.
In summer in Japan, there are fun events such as summer festivals and Comic Market’s. However, I don’t recommend people living in high latitude areas come to Japan in the summer.
