Scorching Heatwave to Grip South Korea: Daytime Highs Reach 37°C, Tropical Nights Expected

South Korea is bracing for intense heat as daytime temperatures are forecast to soar, with highs potentially reaching 37 degrees Celsius on Saturday. Following a period of rain, a rapid temperature increase is expected, leading to the likely expansion of heatwave advisories across the country. This sweltering weather is set to be accompanied by tropical nights, where nighttime temperatures fail to drop below 25 degrees Celsius, affecting most regions.

The Korea Meteorological Administration predicts morning lows between 21-26 degrees Celsius and daytime highs between 29-37 degrees Celsius for Saturday, significantly above the seasonal average. Major cities like Seoul are expected to experience highs around 33 degrees Celsius, with perceived temperatures potentially exceeding 33 degrees in many areas. Some southern parts of South Jeolla Province and the Gyeongsang provinces, along with Jeju Island, are already under heatwave advisories.

The perceived temperature will be higher than the observed temperature in workplaces inside and outside, fields, and roads, so be careful of heat-related illnesses.

Even after the rain ceases, high humidity combined with rising temperatures will intensify the feeling of heat. The meteorological agency warned that perceived temperatures could be even higher than recorded temperatures in outdoor workplaces, fields, and roads, urging caution against heat-related illnesses. Vulnerable populations, including the elderly and those with chronic conditions, are particularly at risk during these prolonged hot periods.

Showers are expected from Friday afternoon into the evening in some inland areas of northern Gyeonggi Province, Gangwon Province, Chungcheong Province, northern Jeolla Province, and western Gyeongsang Province. These showers could be accompanied by strong winds, thunder, and lightning, with rainfall intensity varying significantly even within the same region. Drivers are advised to be cautious of reduced visibility and slippery roads.

In areas where tropical nights occur, it is advisable to drink plenty of water before going to sleep and refrain from caffeine and alcohol. Those vulnerable to heat, such as the elderly and those with chronic illnesses, need to check their health status during the night.
