Extreme weather patterns in South Korea

Overview

South Korea has transitioned from a period of extreme heat to more moderate, though still warm, conditions. Initially, the country faced record-breaking heatwaves, with temperatures in Seoul reaching 40.2°C. This heat was accompanied by heavy rainfall along the eastern coast and Jeju Island, driven by moisture from Typhoon Dolphin.

By mid-August, the extreme heatwave warnings were lifted as overnight temperatures began to drop. Major cities saw an end to prolonged streaks of ‘tropical nights’—periods where temperatures remained at or above 25°C overnight—with Busan ending a 23-day streak and Seoul ending a 17-day streak. While daytime highs remain significant, reaching up to 33°C in several regions, morning lows have decreased. Weather patterns continue to be influenced by tropical systems, with moisture from Typhoon Chan-hom expected to affect rainfall along the east coast.
