A record-breaking heatwave is spreading across the Korean Peninsula, prompting emergency responses in both South Korea and North Korea as temperatures soar to unprecedented levels. The extreme heat, initially concentrated in South Korea’s southeastern region, has expanded into the Seoul metropolitan area and western regions, with forecasts indicating that the high temperatures and tropical nights may persist in the coming days.

In South Korea, the Korea Meteorological Administration (KMA) reported that the city of Yangsan reached 42.5 degrees Celsius (108.5 degrees Fahrenheit) on Sunday, marking the highest temperature recorded since weather observations began 122 years ago. The city had already set new national temperature records in the two previous days. The KMA also issued its first-ever severe heatwave warning for parts of Seoul and Gyeonggi Province, while the highest level heat alerts remain in place for southern areas including Busan, Ulsan, South Gyeongsang, and parts of Gwangju and South Jeolla Province.

South Korean authorities have ramped up emergency measures in response to the heatwave and an associated drought risk. Prime Minister Han Seong-sook has directed ministries and local governments to deploy all available resources to address the situation. The government elevated its heatwave response alert to the second-highest level, enabling additional funding for relief efforts and more frequent inspections in affected regions. Cooling shelters have been expanded in Seoul districts, where free water and sun umbrellas are being distributed. In Yangsan, officials have increased water spraying operations and water supply distribution to help mitigate the impact of the high temperatures.

The Korea Disease Control and Prevention Agency reported that since mid-May, 14 people have died and nearly 1,900 individuals have required medical attention for heat-related illnesses.

Meanwhile, power authorities are monitoring electricity supply closely amid expectations that consumption will hit record levels in late August due to increased air conditioning use. Emergency measures have been activated to manage the heightened demand and prevent power outages.

In North Korea, state media confirmed that temperatures are nearing 40 degrees Celsius (104 degrees Fahrenheit) in some areas, including Pyongyang, which is experiencing its fifth consecutive tropical night. Authorities there have also increased emergency efforts in response to the sustained heat, although specific details on the measures taken remain limited.

The ongoing heatwave presents a significant challenge to public health and infrastructure across the Korean Peninsula as residents seek relief from the intense temperatures at cooling centres, beaches, and water parks. Forecasters continue to warn of sustained heat and emphasize the need for vigilance and protective actions in the coming weeks.
