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.
