In January 2026, the Korea Meteorological Administration (KMA) released an analysis highlighting significant climate anomalies across South Korea. The month was characterized by record-low precipitation and persistent cold spells, attributed to negative Arctic Oscillation and Bering Sea blocking patterns. Average temperatures fell to -1.6°C, 0.7°C below the long-term norm and the lowest since 2018. These findings underscore the importance of ongoing climate monitoring and policy adaptation in response to extreme weather events.
The climate anomalies impacted a wide range of stakeholders, including residents, local governments, and sectors sensitive to weather such as agriculture and disaster management. Notably, the national average precipitation was only 4.3mm—just 19.6% of the norm—making it the second lowest on record. Relative humidity dropped to 53%, the lowest ever recorded, and several regions experienced zero rainfall. The KMA emphasized the increased risks of wildfires and drought due to these dry conditions.
The timeline of January 2026 saw dramatic temperature fluctuations: a brief warm spell from January 15–18 was followed by a sharp and prolonged cold wave from January 20 onward. The KMA issued cold wave advisories for most regions, and the Han River froze seven days earlier than usual. Snowfall was below average, except for localized heavy snow in Mokpo. Sea surface temperatures around South Korea remained high, with the southern coast recording the highest in a decade.
Frequently asked questions include the causes of these anomalies, which the KMA attributes to weakened polar vortex and atmospheric blocking patterns. Another common inquiry concerns the impact on daily life, with authorities warning of heightened wildfire and drought risks. The KMA has committed to enhanced climate monitoring and analysis to support early warning and policy adaptation.
Metaqsol opinion: The January 2026 climate anomalies in South Korea highlight the growing volatility of regional weather patterns. The KMA’s rapid response and transparent reporting are crucial for public safety and policy adaptation. Continued investment in climate monitoring and early warning systems will be essential to mitigate the risks of wildfires, drought, and other extreme events. These developments underscore the need for integrated climate resilience strategies at both local and national levels.
