# South Korea climate variability and temperature extremes > Developing situation record from CLSTR: https://clstr.news/situations/south-korea-climate-variability-and-temperature-extremes > Updated: 2026-11-04T01:00:00.000Z. Sources: 4. Developments: 2. South Korea experienced significant climate volatility during the autumn of 2026. In September, regions such as Gwangju, Jeonnam, and Chungbuk faced higher than average temperatures and exceptionally low precipitation. Specifically, Chungbuk recorded only 11.2mm of rain, which was 7.9% of the average, leading to increased meteorological drought conditions. By October, the weather patterns shifted toward extreme temperature fluctuations. The country recorded its fifth warmest October on record, with a national average of 15.8 degrees Celsius. Seoul reached a record high of 30.1 degrees Celsius on October 12. While the month began dry, it ended with frequent rainfall, resulting in total precipitation that was approximately 1.7 times the normal amount. Scientists have linked these erratic patterns to a super El Nino and high sea surface temperatures in the East Sea. ## Timeline ### 2026-11-04: South Korea experienced record temperature fluctuations in October South Korea saw its fifth warmest October on record, marked by extreme temperature swings and record-breaking heat in Seoul, driven by atmospheric blocking and El Nino effects. 3 sources. https://clstr.news/cluster/south-korea-experienced-record-temperature-fluctuations-in-october ### 2026-10-05: South Korea experiences high temperatures and low rainfall in September South Korean regions including Gwangju and Chungbuk experienced unusually high September temperatures and record-low rainfall, leading to increased meteorological drought and climate volatility. 2 sources. https://clstr.news/cluster/south-korea-experiences-high-temperatures-and-low-rainfall-in-september --- Cite as: South Korea climate variability and temperature extremes.
