Daegu, South Korea / RankWire.AI / – Meteorologists and civil defense officials in South Korea confirmed that the most severe heat alerts were issued for southeastern South Korea, taking effect across key urban centers on Sunday amid a sharp increase in regional temperatures. As reported by Yonhap News Agency, the intense heat wave prompted emergency notifications in Daegu and neighboring industrial cities. Weather monitoring stations in the region reported daytime heat indices soaring well above 30 degrees Celsius in the morning, with temperatures rising even further by early afternoon. Authorities responded quickly, activating emergency measures as extreme atmospheric conditions impacted densely populated urban areas and nearby agricultural districts.

At 11 a.m. local time, the scope of the alerts expanded significantly as municipal safety systems registered rising thermal stress levels across North Gyeongsang Province. Officials from the Korea Meteorological Administration confirmed that highest-level heat warnings now covered southwestern sections of Daegu, Gyeongsan, and the rural county of Cheongdo. Early in the morning, weather officials had already issued the same level of warning for eastern coastal cities, including Pohang and Gyeongju. Monitoring stations reported rapid temperature increases across all affected areas, leading to public advisories on outdoor activity and heat-related health risks.
Measurements taken at 1 p.m. local time showed peak daytime temperatures reaching 38.4 degrees Celsius in Gyeongju, a city with historical significance. During that period, Daegu recorded 35.4 degrees Celsius, while coastal areas like Pohang hit 32.1 degrees Celsius. Experts highlighted that apparent temperatures—which account for humidity—remained significantly higher than the thermometer readings. The extreme heat created dangerous outdoor conditions across industrial zones, farming regions, and transportation hubs in the southeastern part of the Korean Peninsula.
Maximum Heat Wave Warnings Expand Across Provinces
Officials from weather agencies pointed out that these latest alerts mark the first issuance of top-tier thermal warnings under the revised public safety protocols introduced on June 1. According to the updated warning system, a highest-level heat alert is triggered when forecasted daily highs reach 39 degrees Celsius or more, with apparent temperatures hitting at least 35 degrees Celsius for two consecutive days. This modernized threshold aims to improve risk communication and enhance municipal response during severe summer heatwaves nationwide.
Historical data from meteorological records show that the current heatwave follows earlier severe temperature events documented at the start of summer. South Korea issued its first highest-level heat warnings of the year for Gyeongsan and Pohang on July 12, after a period of high humidity and sustained high temperatures. Authorities noted that recurrent heatwaves in North Gyeongsang Province have exerted cumulative thermal stress on infrastructure, power supplies, and agriculture. Local officials have expanded cooling centers and deployed water-spraying vehicles to reduce urban heat island effects along major streets.
Morning Emergency Alerts for Southwestern Daegu
Regional safety agencies advised residents, elderly citizens, and outdoor workers to exercise caution against heatstroke and heat exhaustion. Municipal leaders recommended staying indoors during peak afternoon hours, maintaining proper hydration, and utilizing air-conditioned public facilities. Medical centers and emergency services increased staffing and prepared cooling equipment to treat heat-related illnesses. Transportation authorities also monitored rail lines and roads to prevent structural damage caused by the intense heat.
Meteorological forecasts indicate that high-pressure systems over the Korean Peninsula will sustain elevated temperatures through early week trading hours. Persistent humidity coupled with intense solar radiation is expected to keep apparent temperatures near warning levels in Daegu and surrounding regions. The government’s emergency coordination continues with regional authorities to ensure vulnerable populations are supported until conditions stabilize across the country.
