South Korea is experiencing a nationwide heat wave with temperatures in some regions approaching 40 degrees Celsius this week [1].
The extreme weather has triggered widespread heat warnings and advisories from the Korea Meteorological Administration. These conditions pose significant public health risks as high humidity intensifies the perceived heat across the peninsula [1, 2].
In Gyeongsangbuk-do, the heat has been most severe. Gyeongsan Hayang-eup recorded a temperature of 39.4 degrees Celsius [1], making it the hottest location in the country. Other regions in the south are seeing similar extremes, with Gyeongju reaching 37 degrees Celsius [1], and Yangsan recording 36.8 degrees Celsius [1].
Weather caster Lee Hye-min said the apparent temperature in Seoul has risen to nearly 33 degrees Celsius [1]. The capital city's humidity has contributed to the oppressive conditions, driving residents toward outdoor swimming pools to find relief [1].
Forecasters expect the trend to continue. The maximum temperature in Pohang is forecast to reach 37 degrees Celsius [1, 2]. The combination of atmospheric conditions and high humidity is expected to maintain the "steamer-like" heat across the region [1].
Authorities have issued heat warnings (폭염특보) and heat advisories (폭염경보) to alert the public to the dangers of heat-related illnesses [1, 2]. Residents are encouraged to limit outdoor activity during peak sun hours, and stay hydrated as the heat wave persists.
“Gyeongsan Hayang-eup recorded a temperature of 39.4 degrees Celsius [1].”
The intensity of this heat wave, particularly the near-40 degree readings in Gyeongsangbuk-do, underscores the increasing volatility of East Asian summer weather. When high humidity is paired with these temperatures, the 'apparent temperature' increases the risk of heatstroke, placing a heavier burden on the national healthcare system and urban infrastructure in densely populated cities like Seoul.
