If you think Seoul is already hot, brace yourself. Weather experts are warning that temperatures in parts of South Korea could approach 40°C (104°F) as an intense heat wave continues. While Seoul rarely reaches that level, a combination of strong sunshine, hot air moving north, and warm overnight temperatures could push the city close to a historic record. Authorities are urging people to stay hydrated, avoid outdoor activities during the hottest part of the day, and check on elderly neighbors and family members.

Heat waves have become more common in Korea over the past decade, with tropical nights making it difficult for many people to sleep. Air conditioners, cooling centers, and even convenience stores become popular places to escape the heat. If you’re visiting Korea this summer, plan outdoor sightseeing early in the morning or after sunset.
President Lee Jae Myung ordered an all-out government response as South Korea faces record-breaking heat and drought. He warned that temperatures above 40°C are becoming Korea’s new reality after Yangsan recorded a historic 42°C, the highest temperature since weather records began in 1904.
