Morning temperatures in Daegu, South Korea, neared 33 °C on June 28, 2024, as a nationwide heatwave drove temperatures upward [1].

Extreme heat in this region poses significant public health risks, particularly for outdoor workers and residents in urban areas prone to the heat island effect. The rapid rise in temperature early in the day limits the window for cooling and increases the risk of heat-related illnesses.

By 8:00 KST, temperatures had already climbed above 30 °C [1]. In Bumeo-negeori and other parts of the Daegu-Gyeongbuk region, residents and workers faced a "steaming heat" that began in the early morning hours, YTN reporter 김근우 said [1].

Local authorities issued heat advisories for Daegu and North Gyeongsang Province to warn the public of the escalating conditions [1], [2]. The heat island effect contributed to high nighttime lows, with temperatures remaining around 27 °C [1].

Forecasts for the day varied between reporting agencies. YTN reported that the daytime high was expected to reach 36 °C [1]. However, News1 reported that the recorded afternoon high temperature actually reached 33.6 °C [5].

An anchor for YTN said that heatwave warnings remained in effect for most of the Daegu and Gyeongbuk areas [3]. The combination of high humidity and intense sunlight created a peak in the "scorching heat" across the region [3], [4].

“Morning temperatures in Daegu neared 33 °C on June 28, 2024.”

The temperature disparity between the forecast of 36 °C and the recorded 33.6 °C highlights the volatility of urban heatwaves. When nighttime lows remain as high as 27 °C, the human body cannot recover from daytime heat stress, making heat advisories critical for preventing mass heatstroke in densely populated South Korean cities.
