South Korea battles intense heat wave with temperatures nearing 40°C

Much of South Korea remains under heat advisories as sweltering temperatures continue, with daytime highs forecast to reach between 30°C and 39°C (86°F to 102°F). The Korea Meteorological Administration has issued its highest-level heat wave warning for Seoul, Incheon, most of Gyeonggi Province, and parts of South Jeolla Province.

The maximum heat index values in many areas are expected to approach 35°C (95°F). The oppressive heat is likely to persist through the night, with many regions experiencing tropical nights, where overnight temperatures stay above 25°C (77°F), offering little respite. Forecasters have warned that the extreme heat could be life-threatening in several densely populated areas, including Seoul and parts of Gyeonggi and South Jeolla provinces.

Authorities are urging caution, particularly for outdoor workers, young children, the elderly, and individuals with chronic medical conditions. They are advised to take extra precautions and avoid strenuous activity during the hottest parts of the day. Recommendations include using air conditioners or fans, staying hydrated, and avoiding alcohol and caffeinated beverages before bedtime.

While the primary concern is the heat, some regions may experience scattered showers. Jeju Island is expected to receive around 5 mm of rain, and parts of Daejeon, Sejong, South Chungcheong, and North Jeolla provinces could see between 5 to 20 mm of precipitation. Air quality is anticipated to remain good to moderate nationwide.
