South Korea in December

December in South Korea is cold, festive, and domestically popular for winter-specific activities. The ski resorts open (typically late November to early December), illumination events run across the cities, and the food culture pivots to warming dishes — hot pot (jeongol), rich bone broth soups (seolleongtang, gomtang), and samgyeopsal by the grill. Christmas and New Year add a celebratory dimension to the month.

Weather

Seoul in December averages -3°C to 5°C, with overnight lows sometimes reaching -10°C or below during cold snaps from Siberia. Snow falls, though not always extensively. The air is dry and clear. Wind chill on open streets is significant.

Busan and the south coast are milder at 3–10°C — cold but rarely freezing overnight. Jeju ranges from 8–14°C and is the most comfortable outdoor destination in December. The west coast can be cold and grey.

Things to Do in December

Winter illuminations — Seoul’s major commercial districts and cultural sites put on extensive light installations in December. The Cheonggyecheon Stream, Lotte World, and various department store exteriors are decorated. The Seoul Christmas Festival near Gwanghwamun is a recurring event.

Ski resorts — the main Gangwon Province resorts (Alpensia, Vivaldi Park, High1, Jisan, Phoenix Park) open for the season in late November or early December. Initial snowpack depends on natural conditions supplemented by artificial snow. The season runs through February.

New Year’s Eve and New Year’s Day — the Bosingak Bell Pavilion in Jongno, Seoul, hosts a bell-ringing ceremony at midnight on New Year’s Eve, a tradition with roots in the Joseon era. The 33 strokes of the bell are broadcast nationally. Crowds around Jongno are large for this event.

Jeju Island winter escape — Jeju is the domestic winter getaway of choice for many Korean families. Winter tangerines (hallabong) are in season, the island is far less crowded than in summer, and the coastal walks have a particular bleached, austere quality.

Jjimjilbang culture — public bathhouses with heated floors and communal resting areas are an intrinsic part of Korean winter life. Spending time at a jjimjilbang — bathing, eating ramen from the in-house kitchen, sleeping on the heated floor — is a Korean experience with no real equivalent elsewhere.

Christmas in Korea

Christmas Day is a national public holiday. Christian churches hold services; shopping centres and commercial areas are decorated and active throughout December. It is observed more as a social occasion than a family-gathering holiday (that role belongs to Seollal and Chuseok). Couples and friends are the main social dynamic for December festivities in Seoul.

Crowds and Prices

December is shoulder to low season for international visitors outside major holidays. Flights and accommodation in central Seoul are often reasonably priced in early to mid-December. The Christmas-to-New Year week picks up. Ski resort accommodation in Gangwon Province is in demand from December onward.

What to Pack

Heavy winter clothing: down jacket, thermal layers, warm hat, gloves, scarf. Boots with good insulation and grip for icy pavements. Hand warmers are available cheaply at convenience stores throughout Korea.
