# Seoul Records Earliest Seasonal Snowfall in Years South Korea's capital experiences first snowfall significantly ahead of historical seasonal averages. - **Source:** [The Straits Times – Asia](https://www.straitstimes.com/asia) - **Published:** 2026-11-08 - **Topic:** [science](https://brifing.si/c/science) - **Original article:** - **On Brifing:** https://brifing.si/s/b668f18e-f8bf-4fd2-83b2-559c4d227cde ## Early Winter Arrival Seoul officially recorded its first snowfall of the season on November 8. The Korea Meteorological Administration confirmed the observation occurred at 10am in the Songwol-dong district of Jongno-gu. This event marks a notable shift in the local climate calendar, arriving significantly earlier than residents typically expect during the late autumn transition period. ## Statistical Deviation Analysis The snowfall arrived 26 days earlier than the 2025 record and 12 days ahead of the long-term seasonal average. While this timing is statistically early, the agency notes that such occurrences are not unprecedented. Similar early November snow events were previously documented in the city during the years 2002 and 2010. ## Official Observation Standards The official designation of the first snowfall is determined strictly by standardized weather station observations rather than anecdotal reports from city residents. This methodology ensures consistency in meteorological record-keeping across decades. By relying on specific station data in Jongno-gu, the agency maintains a precise historical timeline for tracking regional climate patterns. ## Historical Context Comparison Despite the early arrival, the current event remains well within historical bounds for the region. The earliest recorded first snowfall in Seoul since 1973 occurred on October 23, 1981. Comparing current data against these long-term records helps meteorologists understand the variability of winter onset in the Korean peninsula over several decades. ## Lunar Calendar Alignment The snowfall coincided closely with 'ipdong', a traditional marker on the lunar calendar signifying the onset of winter. The weather agency also reported the first ice of the season on the same Saturday. These combined indicators suggest a rapid transition into colder temperatures across the metropolitan area following the initial snow. ## Meteorological Agency Role The Korea Meteorological Administration serves as the primary authority for tracking these seasonal shifts. By monitoring both snow and ice formation, the agency provides essential data for public safety and infrastructure planning. Their observations form the basis for understanding how seasonal transitions are evolving in the context of broader environmental changes. ## Urban Climate Dynamics Seoul's geography and urban density often influence localized weather patterns, making precise station monitoring critical. The Songwol-dong station provides a consistent baseline for the city's climate history. Understanding these early winter signals allows for better preparation regarding urban heating demands and potential impacts on transportation networks during the colder months. ## Future Seasonal Outlook While this early snowfall provides a snapshot of current weather variability, it underscores the importance of continuous monitoring. As seasonal averages fluctuate, the data collected from this event will be integrated into future climate models. Observers will continue to track temperature trends to determine if this early start indicates a longer winter. ## Sources covering this story - https://www.straitstimes.com/asia/east-asia/seoul-records-first-snowfall-26-days-earlier-than-2025 — --- _Summary written by Brifing from the original reporting.
