Soseo, one of the 24 seasons of the lunar calendar, which fell on Monday, traditionally marks the beginning of scorching summer heat. And the daytime high in Seoul on Monday did soar to 33.8 degrees, the highest in 14 years for early July.
The Korea Meteorological Administration predicted that the heat wave will continue to grip the country, with temperatures in Seoul reaching 31 degrees on Tuesday and 33 on Wednesday.
The KMA blamed typhoon Neoguri. As it advances northward, it is pushing up hot and humid air, which comes in contact with a cold air mass hovering over the Korean Peninsula, creating showers and so-called tropical nights.
Neoguri, which is likely to become a super typhoon, will reach up to 280 km south of Jeju Island, by Wednesday afternoon and then turn east toward Kyushu, Japan.
Neoguri means a raccoon in Korean, and it was one of the names submitted by Korea to the World Meteorological Organization.
The 14 member states propose 10 names for a pre-designated list that are then assigned to typhoons in the order they arise.
