Winter Storm Warnings in Seoul, South Korea
Seoul experiences a cold, dry winter shaped by Siberian air masses that push temperatures well below freezing. Across the 13 years analyzed from 2012 through 2024, the city averaged 6.6 inches (16.7 cm) of snowfall per year — enough to dust streets and disrupt traffic, but rarely enough to paralyze the city for extended periods. The snowiest months tend to be February, December, and January, in that order, when cold continental air occasionally collides with moisture from the Yellow Sea to produce meaningful accumulations.
Average winter overnight lows hover around 21.3°F (−5.9°C), meaning even modest snowfall can compact into ice on roads and sidewalks, creating hazards that outlast the storm itself.
Notably, the data shows zero heavy-snow or major-snow days per year on average, which reflects how infrequently Seoul sees the kind of extreme accumulation that would trigger a formal winter storm warning. When such warnings are issued by the Korea Meteorological Administration, they signal conditions that exceed typical thresholds — thresholds that vary by region across the Korean Peninsula. A warning here carries real weight precisely because significant snow events are uncommon, and infrastructure and residents may be less prepared than in snowier climates.
