Summer is starting earlier and earlier in Korea, with temperatures reaching 30 degrees Celsius or more in mid-May.
The Korea Meteorological Administration forecast Sunday that the daytime high in Daegu would soar to 31 degrees on Monday, and similar temperatures are expected in Cheongju, North Chungcheong Province, Jeonju, North Jeolla Province, and Wonju, Gangwon Province.
The KMA said that the midsummer weather will continue nationwide throughout this week.
Earlier last week, Gyeongsan in North Gyeongsang Province and Ulsan in South Gyeongsang Province saw daytime highs climb to 32.2 degree. Such temperatures are usually seen in midsummer.
According to the KMA, summers in the 1910s started on June 10 and lasted for 94 days. In the 2000s, summer began on May 27 and lasted for 121 days.
This will have serious implications for health as people’s bodies are not given enough time to get used to sudden heat.
A prolonged series of clear days also increases the ozone density, which can cause respiratory problems and skin cancer.
There is also a likelihood of more torrential rain this summer.
