As of August 4, 2026, the Korea Meteorological Administration placed all 25 districts of Seoul under an extreme heat warning — the country's highest heat alert level. The alert expanded to the city's northeast and northwest areas at 11 a.m., completing citywide coverage after the southern districts were placed under the same warning a day earlier. Parts of nearby Gyeonggi Province, plus Jeonju and areas of North and South Jeolla provinces, received the same warning at the same time.

Key points

The extreme heat warning expanded to Seoul's northeast and northwest districts at 11 a.m. on Aug. 4, putting the entire city under the alert.
It's the first time Seoul has hit this top-tier warning since the system was introduced in June this year.
Parts of Gyeonggi Province (Goyang, Osan, Hanam and more), Jeonju in North Jeolla, and areas of South Jeolla received the same warning simultaneously.
President Lee Jae-myung told a Cabinet meeting the heat wave amounts to a national disaster and ordered that workers' right to halt work actually be enforced.

The heat isn't letting up, and now all of Seoul sits under the country's most severe heat warning. The alert kicks in when the heat index tops 35°C for more than two straight days and is forecast to climb to a 38°C heat index, or an actual temperature of 39°C — a threshold serious enough that even healthy adults are advised to stay indoors. By late morning, the Jongno district weather station had already cleared 33°C, with Sindaebang-dong in Dongjak hitting 34.8°C and the Gangnam-Geumcheon corridor pushing 34.7°C — much of downtown flirting with the 35-degree mark.

The expanded warning wasn't limited to Seoul. Goyang, Osan, Hanam, Anseong, southern Paju and Yongin in Gyeonggi Province, along with Jeonju in North Jeolla and Jangseong and Gokseong in South Jeolla, all received the same top-level alert at the same time. Some southern regions had it worse for longer: Boseong, Yeosu and Gwangyang in South Jeolla have been under the warning since Aug. 1, and Suncheon, southern Gokseong and eastern Gwangju since the day before — meaning the heat has been piling up in the south for days.

The government is treating this as serious business. Chairing a Cabinet meeting, President Lee Jae-myung declared the current heat wave a national disaster and stressed that workers' legal right to stop work in dangerous conditions needs to be a real, enforced protection — not just a rule on paper. The Ministry of the Interior and Safety sent emergency alerts urging people to avoid unnecessary outings, stay hydrated, and check in on vulnerable neighbors, including elderly residents and people with chronic conditions.

The toll is climbing. Korea's disease control agency counted 18 new heat-related patients in Seoul in a single day, and the cumulative count since mid-May now stands at 185, including two deaths. In response, Seoul has kept its heat crisis alert at Level 2 and expanded its response operation to eight task teams.

On the ground, Seoul has turned roughly 4,000 senior centers and community welfare facilities into cooling shelters, plus more than 400 convenience stores and banks serving as "climate commute shelters," alongside emergency evacuation sites and rest areas for outdoor workers. Around 180 misting stations are spraying cooling fog across the city, and water trucks are out spraying down streets. Forecasters expect the heat and tropical nights to continue for now.

In Korea right nowIn Korea, Seoul hitting this top-tier alert is itself being treated as a landmark moment — the first time the entire capital has been covered since the system launched. With the president personally invoking "national disaster" language and workers' right to stop work, the heat wave has shifted from a weather story to a workplace-safety story. Daily updates on heat-related deaths and patient counts are keeping health advice trending online.
