South Korea in December 2026: First Winter Month for Ski

December, the true beginning of winter in South Korea, brings crisp air, chilly temperatures, and a festive atmosphere with Christmas lights. You can see parts of the country dusted in snow as ski resorts begin to come alive. But how cold does it actually get, and is it still a good time to take a South Korea tour? Find everything you need to know about South Korea's December weather, what to wear, and what to do in this guide.

South Korea Weather in December

As the first and warmest month of winter, December in South Korea is cold and dry, with temperatures dropping noticeably from November. Seoul averages 4℃ (39℉) high and -3℃ (27℉) low, while southern destinations such as Busan and Jeju Island remain much milder. Cloudy and windy days are common, so even when the thermometer does not seem extremely low, it can feel quite cold outdoors.

The first half of December can still feel like brisk late autumn, but winter becomes more noticeable as the month progresses. Seoul can see occasional snowfall, while colder mountain areas such as Pyeongchang are more likely to have snow and below-freezing temperatures. By December, ski resorts in and around Pyeongchang are in the winter season, making it a popular choice for skiing, snow activities, and winter scenery.

Daylight hours are also shorter in South Korea in December, with sunset before 6 pm. Combined with the wind chill, it can feel colder than the actual temperature, especially during the early morning and at night.

	Average High	Average Low	Rainy Days
Seoul	4℃ (39℉)	-3℃ (27℉)	about 4 days
Pyeongchang	4℃ (39℉)	-7℃ (19℉)	-
Busan	11℃ (52℉)	3℃ (37℉)	about 5 days
Jeju Island	12℃ (54℉)	6℃ (43℉)	about 10 days

• Seoul: Cold in December, with below-freezing temperatures at night and occasional snowfall. Christmas lights and winter scenery add a festive atmosphere to the city.
• Pyeongchang: Colder and more likely to see snow, making it a good choice for skiing and other winter activities.
• Busan and Jeju Island: Much milder than Seoul and Pyeongchang, with average lows remaining above 0℃ (32℉), although snow is less common.

December Travel Cost & Crowd in Korea

December is generally a quieter travel season in South Korea, especially in the first half of the month. However, Christmas, the winter ski season, and the year-end period can bring more visitors and higher demand in certain destinations.

• Early December (Dec 1 to 15): Generally offers fewer crowds and more opportunities for lower accommodation rates, particularly in Seoul and Busan. Popular attractions are usually easier to visit at a relaxed pace, and there is a wider choice of hotels.
• Mid to Late December (Dec 16 to 25): Visitor numbers and prices may gradually increase as Christmas approaches. Central areas of Seoul and Busan become livelier, with Christmas lights and seasonal events, while ski resorts can also become busier during the winter season.
• Year-End & New Year Period (Dec 26 to 31): Year-end travel can bring increased movement around major cities and winter destinations. New Year's Eve is particularly lively around places such as Bosingak Pavilion in Seoul, while popular hotels and transportation may be busier than earlier in the month.

What to Do in Korea in December

Enjoy the Early Ski Season

December marks the beginning of the ski season in South Korea, with more reliable snow conditions developing in the second half of the month. Pyeongchang and other ski areas in Gangwon are good choices for skiing, snowboarding, and other winter activities. Many resorts offer equipment rental, ski lessons, and beginner-friendly slopes, making them accessible even if it is your first time skiing. Even without skiing, you can enjoy the snowy mountain scenery, resort cafés, and other winter activities.

• Ski Resorts in and around Pyeongchang: Yongpyong Resort, Phoenix Park, High1 Resort
• Ski Resorts Around Seoul: Konjiam Resort, Jisan Forest Resort

Explore Seoul's Palaces in Winter

December brings a quieter atmosphere to Seoul's historic palaces, with bare trees and occasional snow creating a distinctly winter setting. Visit Gyeongbokgung Palace or Changdeokgung Palace in the morning, when the winter light is softer and the grounds are generally quieter. You can then continue to nearby Bukchon Hanok Village or stop at a traditional tea house or café to warm up. On very cold or snowy days, keep outdoor sightseeing shorter and leave more time for indoor stops.

A traditional hanbok experience is also possible in December, especially on a sunny winter day, although the cold weather means outdoor photo time is best kept relatively short.

Relax at a Korean Jjimjilbang

A visit to a Korean jjimjilbang, or traditional sauna, is a relaxing way to warm up during a cold December day. Beyond hot baths and saunas, many jjimjilbangs have heated rooms, relaxation areas, and places to rest or enjoy a snack. Some larger facilities are open 24 hours, making a jjimjilbang an easy addition to a winter itinerary in Seoul or other major cities. It is also a chance to experience a familiar part of everyday Korean culture rather than simply visiting another sightseeing attraction.

Head South for Milder Weather

If you prefer milder winter weather, Busan and Jeju Island are warmer alternatives to Seoul and the northern mountain areas. In Busan, you can enjoy coastal views, visit Gamcheon Culture Village, and explore the city's markets and cafés without dealing with Seoul's colder temperatures. On Jeju Island, winter is a good time for coastal walks, scenic viewpoints, and seasonal camellia blooms, while hiking conditions on Mt. Halla depend on the weather and snow conditions.

Celebrate Christmas in Korea

Christmas is a national holiday in South Korea, but the atmosphere is more urban and commercial than the traditional family-centered Christmas celebrations common in many Western countries. In Seoul and other major cities, you can see illuminated streets, decorated cafés, department stores, and shopping districts throughout December. Christmas is also particularly popular among couples and younger generations, making it an interesting time to experience Korea's modern holiday culture.

For a festive winter trip, you can also combine Christmas activities with winter scenery, seasonal cafés, and a few days at a ski resort. See our guide to Christmas in Korea for more ideas.

Local Festivals and Events in December

December also brings several seasonal festivals and events across South Korea, from winter light displays to New Year celebrations.

• Garden of Morning Calm Lighting Festival: The gardens are illuminated with millions of lights from December through winter, covering trees, pathways, and themed garden areas. It is particularly appealing for couples and families looking for an evening winter activity.
• Seoul Lantern Festival: Held along Cheonggyecheon Stream in central Seoul, the festival features large-scale lantern installations inspired by Korean culture, history, and seasonal themes. It is easy to explore on foot as you follow the stream through the illuminated displays.
• Seongsan Sunrise Festival: Held around New Year's Eve and New Year's Day on Jeju Island, this festival brings visitors to Seongsan Ilchulbong to welcome the New Year and watch the first sunrise. The celebration combines the sunrise experience with local performances and festive activities.
