South Korea faces extreme heat, with highs up to 37 C and widespread tropical nights

South Korea is bracing for intense heat as temperatures are forecast to soar, with the highest perceived temperatures reaching 33 degrees Celsius across most of the country and peaking at 37 degrees Celsius in some areas. The Korea Meteorological Administration (KMA) predicts that this oppressive heatwave will continue until at least tomorrow.

Many regions are also expected to experience tropical nights, a phenomenon where nighttime temperatures fail to drop below 25 degrees Celsius (77 F). This is due to insufficient cooling overnight, contributing to the overall discomfort. The KMA noted that while areas receiving rain or showers might see temporary temperature drops, the high humidity will persist, keeping the heat oppressive even after precipitation.

Daytime high temperatures are projected to be between 30 and 37 degrees Celsius, significantly above the seasonal average. Central regions, North Jeolla Province, and North Gyeongsang Province are particularly expected to experience highs around 35 degrees Celsius. Scattered showers and thunderstorms are anticipated in some parts of the country, including the Seoul metropolitan area, Gangwon inland and mountainous areas, Chungcheong Province, and North Jeolla Province, with rainfall amounts varying.

Coastal areas, specifically the West Sea's outer waters, Jeju waters, and the South Sea's outer waters, are under a strong wind advisory. Winds are expected to blow at speeds of 9 to 21 meters per second, with waves reaching 2 to 4 meters. Mariners and fishermen are advised to exercise extreme caution. Additionally, coastal areas of Jeju, South Jeolla Province, and the coastal regions of Gyeongnam Province may experience high waves due to swells, posing a risk to beaches, rocky shores, and breakwaters. Authorities are urging vigilance to prevent accidents.
