South Korea issued emergency heat wave instructions as the country sweltered, with its highest temperature on record reported in the southeastern city of Yangsan. The national meteorological agency activated the alert system to warn residents of dangerous heat conditions expected to persist across multiple regions.

Authorities advised vulnerable populations, including the elderly and young children, to seek air-conditioned spaces and stay hydrated. Public facilities, including community centers and libraries, were opened as cooling shelters for residents without access to air conditioning.

The record-breaking temperature underscores the growing impact of extreme weather events linked to climate change in East Asia. Officials emphasized ongoing monitoring and readiness to deploy additional resources if conditions worsen.
