South Korea has expanded extreme heat warnings to parts of Gyeongsangbuk-do and Jeollanam-do as temperatures rise nationwide [1, 2].

The expansion of these warnings comes during Jungbok, the third of the three hottest days of the summer season. This period typically marks a peak in intensity for heatwaves across the peninsula, necessitating heightened public safety measures to prevent heat-related illnesses.

Weather officials have issued specific alerts for Gyeongju, Daegu, and Pohang in Gyeongsangbuk-do, as well as Gwangyang in Jeollanam-do [1, 2]. The temperature in Gyeongju is forecast to reach a maximum of 38°C [1]. Meanwhile, officials expect maximum temperatures in Gwangyang and Daegu to hit 37°C [1].

In the capital, the heat is already impacting residents. The current apparent temperature in Seoul has reached 31°C [1]. A weather caster for YTN said, "The weather is very sticky."

Forecasters expect the heat in the capital to intensify throughout the day. The general forecast for Seoul is 32°C [1], though the maximum apparent temperature is expected to soar to 34°C [1].

Local authorities are monitoring the situation as the extreme heat warning, known as the 폭염중대경보, covers more territory to manage the risks associated with the high humidity and temperature spikes [1, 2].

“The temperature in Gyeongju is forecast to reach a maximum of 38°C.”

The expansion of the extreme heat warning during Jungbok highlights the seasonal volatility of the Korean peninsula's climate. By targeting specific hubs like Gyeongju and Daegu, the government is attempting to mitigate the risks of heatstroke and infrastructure strain during the most oppressive window of the summer cycle.
