South Korea recorded its highest-ever temperature on Sunday, with Yangsan reaching 42.5°C (108.5°F), marking the fifth consecutive day that temperatures in the city exceeded 40°C. Authorities issued emergency heatwave alerts across more than 20 localities as a result of the extreme heat.

The Korea Meteorological Administration (KMA) urged people to 'immediately stop all outdoor activities' and seek cool places such as designated cooling centers or shaded areas. An emergency alert is issued when areas experiencing a heatwave are forecast to hit perceived temperatures of 38°C or an actual temperature of 39°C for the day.

The extreme heat has disrupted daily life across the country, with residents seeking refuge in air-conditioned spaces like shopping malls, cafes, and homes. The KMA warned that temperatures could rise further in western regions this week. Prime Minister Han Seong-sook ordered ministries and local governments to mobilize all available resources to respond to heatwave and drought risks, after the government raised its heatwave response alert to the second-highest level.

According to data from the KMA, the average annual number of heatwave days in South Korea has more than doubled over the past five years. On Sunday alone, 14 people died and 1,889 suffered heat-related illnesses since mid-May, as reported by TimesLIVE.

The record-breaking temperatures have also affected other parts of the Korean Peninsula. Forecasters said on Monday that extreme heat, previously concentrated in South Korea’s southeast, was spreading into the Seoul metropolitan area and other western regions. North Korean state media also reported temperatures approaching 40°C in parts of the country and a fifth straight tropical night in Pyongyang.

Power authorities have activated emergency measures and are closely monitoring supply and demand as electricity consumption is expected to reach a record high in late August amid surging air-conditioning use. Severe heatwave warnings have been issued across parts of southern South Korea, including Busan, Ulsan, South Gyeongsang, and parts of Gwangju and South Jeolla province.

Local governments have scrambled to protect vulnerable residents by expanding cooling shelters and distributing free water and sun umbrellas. Yangsan has expanded water-spraying operations and water distribution. The extreme heat also led to the cancellation of a professional baseball game in Changwon, marking the second consecutive cancellation due to extreme heat.

Scientists warn that such extreme weather events are becoming more frequent and intense as a result of human-induced climate change, compounded by natural phenomena like El Niño.
