## Summary

South Korea's Korea Meteorological Administration confirmed on August 2 that the city of Yangsan in South Gyeongsang Province recorded 42.5°C (108.5°F), the highest temperature in the country since national weather observations began. South Korean media described it as the first extreme heatwave of its kind in 122 years. The government activated an emergency response, and more than 20 localities issued emergency heat alerts. The record came during a continuing heatwave that gripped the country's southern regions over the weekend, part of what regional outlets are calling a year of climate extremes across Asia. No immediate casualty figures were reported in the crawl docs.

## Why it matters

South Korea's power grid, agriculture, and outdoor workers are exposed to a new band of heat that its infrastructure was not designed for. The 42.5°C record, a full degree beyond prior known highs, signals that South Korean planners now face a [The Quiet Shift](/en/head/the-quiet-shift) in the country's temperature ceiling, with implications for cooling energy demand, Water supply, and long-term urban planning.

## What to watch

- Whether the KMA issues a formal national emergency declaration and any overnight low temperature readings that would signal the wave is breaking
- Heat-related fatality or hospitalisation figures from South Korea's Ministry of Health and Welfare
- Whether the record triggers a revision to South Korea's climate adaptation benchmarks or building codes
