The Korea Meteorological Administration expanded a severe heatwave alert to all of Seoul on Tuesday after temperatures in Gangnam-gu reached 39.2 degrees Celsius [1].
The escalation of the alert signals a critical public health risk for millions of residents. Extreme temperatures of this magnitude increase the likelihood of heatstroke and put significant strain on the city's power grid during peak cooling hours.
Officials said the warning was issued after daily maximum perceived temperatures remained above 35 degrees Celsius for more than two days [2]. This persistent heat has triggered emergency protocols to protect vulnerable populations, including the elderly and outdoor workers, across the metropolitan area.
While some reports indicated that the highest level of alerts were limited to Gyeongsan and Pohang, other sources said the severe alert expanded to the entirety of Seoul [1], [2]. The discrepancy highlights the rapidly shifting weather patterns currently affecting the peninsula.
Forecasters expect the heat to intensify further in the coming days. According to meteorological data, the national heatwave is projected to reach its peak on Aug. 13 [3].
Local authorities said citizens should avoid outdoor activities during the hottest parts of the day and utilize designated cooling centers. The government is monitoring the situation closely as the region prepares for the predicted peak of the summer heat [3].
“Temperatures in Gangnam-gu reached 39.2 degrees Celsius”
The expansion of severe heat alerts to the capital reflects an intensifying trend of extreme summer weather in South Korea. With the heatwave expected to peak on Aug. 13, the city's infrastructure and public health systems will face a critical test in managing urban heat island effects and ensuring energy stability.
