Seoul & Northwest (Gyeonggi, Incheon, Yellow Sea coast)
By December the city is back to cold, dry winter weather with frequent blue skies and short daylight hours. Occasional snowfalls can transform palaces and hanok villages into photogenic scenes, though accumulation is usually modest in the metro area. Travelers should pack a warm coat, hat and insulated shoes for comfortable sightseeing; seasonal markets and street food are particularly inviting after sundown.
Gangwon Province & the Taebaek Mountains (Sokcho, Pyeongchang, Seoraksan)
December resumes true winter conditions in the Taebaek Mountains with reliable snow cover at ski areas and frozen alpine ridgelines. Coastal towns are windy and brisk but rarely see the depth of inland mountain snow; winter festivals and hot springs are popular ways to warm up after cold days outdoors. Travelers should prepare for icy roads and book transfers with drivers experienced in snowy conditions.
Central Korea (Chungcheong, Daejeon, Cheongju, Boryeong)
December returns to cold, mostly dry conditions with short days and clear skies; snow is possible, especially in upland areas, though the flat central plain receives only occasional accumulation. Hot springs and indoor cultural venues provide cozy alternatives to outdoors exploration. Travelers should pack insulated clothing and sturdy footwear for any surprise icy patches on rural roads and trails.
Yeongnam / Southeast (Busan, Daegu, Ulsan, Gyeongsang)
December is mostly dry and chilly, with clear skies and bracing sea breezes on the southeast coastline; Busan’s streets are quieter and less humid than summer. Snow is uncommon in the port itself but may dust the nearby hills. Travelers should bring warm clothing for seaside evenings and enjoy lower accommodation rates outside major holiday periods.
Jeolla & Southwest (Gwangju, Mokpo, Suncheon, Boseong)
December is cool and dry with clear skies; coastal winds feel brisk, and inland Gwangju gets colder at night. The tea fields look dormant but photogenic, and local markets remain a warm refuge. Travelers should bring a warm coat for evening walks and be prepared for shorter daylight hours when planning sightseeing itineraries.
Jeju Island (Hallasan, Seogwipo, Jeju City, Udo)
