South Korean weather authorities are maintaining extreme heat warnings across parts of the Yeongnam region as daytime temperatures approach 39°C [1].
The persistence of these temperatures marks a critical shift in the seasonal weather pattern, effectively ending the summer monsoon season. This transition brings an immediate risk of heat-related illness as the region faces sustained, high-intensity heat.
The extreme heat warning, known as *jungdae-gyeongbo*, is currently in effect for six specific locations: Gwangyang, Goryeong, Pohang, Gyeongju, Yangsan, and Uiryeong [1]. To trigger this specific warning level, weather authorities require a perceived temperature of 38°C or an actual temperature of 39°C sustained for at least one day [1].
"The momentum of the heat wave is becoming increasingly severe," a YTN News anchor said [1].
The heat is not limited to the daytime hours. Tropical nights have appeared across most of the country, keeping minimum temperatures high even after sunset. In Busan, the morning minimum temperature reached 28.2°C [1]. Other urban centers reported similar conditions, with Gwangju at 27.2°C, and Seoul and Daejeon both recording 26.8°C [1]. Gangneung recorded a slightly lower morning minimum of 25.4°C [1].
"Extreme heat warnings are being maintained in some areas of Gyeongbuk and Gyeongnam," a reporter said [1].
The combination of high humidity and extreme peaks in temperature creates a dangerous environment for outdoor workers and elderly populations. Local authorities continue to monitor the Yeongnam region as the heat wave settles in following the rainy season.

The transition from the monsoon season to an extreme heat wave indicates a period of high atmospheric stability and humidity. When the rainy season ends abruptly with temperatures hitting the 39°C threshold, it often leads to a prolonged period of 'tropical nights,' where the lack of nocturnal cooling increases the physiological stress on the population and strains energy grids due to air conditioning demand.
