Korea in winter: how cold it gets, what's on, and whether it's worth going

You’ve found cheap flights for January, or winter is simply when you can get time off, and now you’re wondering whether you’ll spend the whole trip freezing. Seoul in winter is cold, sometimes sharply so, but it’s also the driest time of year, and outside the holidays it’s off-peak for visitors. Most of what makes a Seoul trip good still works, and a few things only happen in winter.

The short version

Korea in winter is worth it if you pack properly and your trip is built around cities, food, markets, spas and a festival or two. It’s the wrong season if you mainly want hikes, beaches or long scenic days outside.

December has the lights and the Christmas markets. January is the coldest month and the peak for ice festivals and skiing. February is still cold, and in 2027 it brings Seollal, the Lunar New Year, from February 6 to 9. Busan and Jeju are milder than Seoul, but neither is warm.

How cold it actually gets

The Korea Meteorological Administration’s 1991 to 2020 normals put Seoul’s January average at -1.9°C. That’s the whole day and night together, so afternoons can be a few degrees above zero while early mornings sit well below it.

The average hides the cold snaps. On January 2, 2026, Seoul was at -11.2°C at 8 a.m., and in late January forecasters expected a week of mornings below -10°C, with strong wind making it feel colder. Plan for at least one spell like that.

Snow is less common than people picture. Seoul’s normal first snow is around November 20, but December to February brings only about 5% of the year’s rain and snow (67.6 mm in total). Expect more dry days than snowy ones in the city. If you want deep snow, the ski areas and Hallasan are a better bet.

Two other things to know. Days are short: Seoul’s sunset on December 31 is at about 5:24 p.m., and sunrise on January 1 at about 7:47 a.m. And the air isn’t always clean. Seoul runs its fine dust seasonal measures from December to March because high-dust days are frequent then, so check the air quality forecast each morning and carry a KF94 mask if you’re sensitive. The best time to visit guide has month-by-month weather for the rest of the year.

What’s good about a winter trip

The honest case for winter is that Seoul is an indoor-friendly city. Markets, food streets, department store food halls, museums, cafes and underground shopping arcades all carry on as normal, and none of them care what the temperature is outside.

Winter food is a real reason to come. Street stalls sell hotteok (sweet filled pancakes), bungeoppang (fish-shaped pastries with red bean) and roasted sweet potatoes, and Korea’s hot soups and stews are made for this weather.

A jjimjilbang, the Korean bathhouse and sauna, makes the most sense in winter. A few hours in the hot pools is the easiest way to thaw out after a cold day of walking. Our jjimjilbang guide explains how they work, and the rainy day Seoul guide lists indoor plans that work just as well on a freezing day.

Spring blossoms and autumn leaves are the big draws, so those are the seasons to book furthest ahead. Winter is the off-season for that kind of sightseeing, though the Seollal break still brings crowds.

Festivals, ice and skiing

Seoul’s winter lights. The city’s Seoul Winter Festa ran from December 12, 2025 to January 4, 2026, its third year, after drawing 5.4 million visitors the year before. It spreads across Gwanghwamun Square, Cheonggyecheon Stream, Seoul Plaza and Dongdaemun Design Plaza (DDP). The Seoul Lantern Festival lines Cheonggyecheon with light sculptures, Gwanghwamun gets a Christmas market and media facade shows, the Bosingak bell is rung at midnight on December 31, and DDP holds a New Year countdown. The 2026-27 dates hadn’t been announced when we checked, but the pattern has been mid-December to early January.

The Seoul Plaza ice rink. In front of City Hall, the rink ran from December 19, 2025 to February 8, 2026. One hour costs 1,000 won, including skate and helmet rental. It was open 10 a.m. to 9:30 p.m. Sunday to Friday and until 11 p.m. on Saturdays and public holidays, with late hours on Christmas Eve and New Year’s Eve. It can close for bad weather or poor air. It’s one of the cheapest fun things to do in Seoul.

Ice-fishing festivals in Gangwon. The big one is the Hwacheon Sancheoneo Ice Festival, held on a frozen river in Hwacheon, about 90 km northeast of Seoul. The 2026 edition ran January 10 to February 1 and passed a million visitors in about two weeks. You fish for trout through holes in the ice, and there’s night fishing, bare-hand fishing, sledding, and foreigner-only fishing and rest areas. The fishing program cost 15,000 won, with about 5,000 won of that returned to spend locally. For 2027 the county is considering about 25,000 won for adults, with the rebate rising to about 15,000 won. The Pyeongchang Trout Festival, by the Oedae Stream in Jinbu, ran January 9 to February 9, 2026, with ice fishing, snow sledding and snowmobile rides.

Skiing. Most of Korea’s big ski resorts are in Gangwon. For the 2025-26 season, Phoenix Snow Park and Mona Yongpyong in Pyeongchang opened on November 21, High1 on November 28, and Gonjiam and Vivaldi Park in early December. Some resorts open with only a slope or two and add more through December, and opening days depend on how cold it is for snowmaking. Mona Yongpyong planned its season-closing event for late February.

Outside Seoul, the Garden of Morning Calm in Gapyeong runs a light festival on winter evenings (check the dates), and our Nami Island verdict covers it along with Nami in snow.

Seollal, Christmas and New Year

Seollal 2027 runs from Saturday, February 6 to Tuesday, February 9. Many Koreans travel to see family, so book KTX seats and domestic flights as early as you can. Some small restaurants and shops may close, especially on Seollal day itself.

There’s an upside. Over the 2026 Seollal break, Gyeongbokgung, Changdeokgung, Deoksugung, Changgyeonggung, Jongmyo and 22 royal tombs were free to enter for five days (Changdeokgung’s Secret Garden excluded). They all closed on the day after the holiday, so don’t plan a palace visit for February 10, 2027 without checking.

Christmas (December 25) is a public holiday, and it falls in the middle of Seoul’s winter lights and markets, so expect busy evenings around Gwanghwamun and Cheonggyecheon. New Year’s Eve brings the Bosingak bell and the DDP countdown, but the big family holiday of the Korean winter is Seollal, not January 1.

Busan, Jeju and the mountains

Busan and Jeju City average a few degrees above Seoul in January (the table in our best time to visit guide has the numbers), but that still means coat weather, not beach weather. Both are fine for walking on clear days.

Jeju’s mountain is a different story. Hallasan gets real snow: on January 2, 2026, 13.3 cm fell on its Samgakbong peak in one cold snap. From October 1 to March 31 the trails use winter cut-off times. Entry starts at 5 a.m., but Donnaeko closes to new hikers at 10 a.m., Seongpanak and Gwaneumsa at 11:30 a.m., and Eorimok and Yeongsil at noon. Seongpanak and Gwaneumsa, the two summit trails, need a reservation. There are also afternoon deadlines for coming back down, and trails can close in weather warnings. The park asks hikers to bring crampons, gloves, warm water and spare clothes, and to check for icy trails after snow.

Mistakes that catch visitors out

Packing for the average. -1.9°C sounds manageable until a cold wave takes the morning to -11°C. Bring a proper down coat, a hat, gloves and thermal layers, not just a jacket.

Planning long outdoor days. With sunset before 5:30 p.m. and freezing wind, a full day of walking outside is hard work. Do palaces and viewpoints in the morning, then move indoors.

Booking Seollal travel late. If your dates touch February 6 to 9, 2027, book trains and domestic flights as soon as they open.

Assuming snow. Seoul’s winter is mostly dry. If snow is the point, head for Gangwon’s mountains or Hallasan, not the city.

Forgetting the air. A clear cold day can still be a high-dust day. Check the forecast before you plan a viewpoint.

Trusting last year’s festival dates. Hwacheon is being reworked for 2027, and Seoul’s winter events are announced only weeks ahead. Check before you build a trip around one.

What we’d do

First trip, five days or fewer: Come in mid-December to early January if you can. You get Seoul’s lights, the skating rink and the markets, and you avoid Seollal. Plan mornings outdoors and afternoons in markets, museums and a jjimjilbang.

You want snow and winter sports: Go in mid-January. Spend a day or two at a Gangwon ski resort or the Hwacheon ice festival, and add a night in Pyeongchang rather than rushing back to Seoul the same day.

Budget or quiet travel: Late January or late February, avoiding the Seollal week. It’s cold, but you skip the spring crowds and the summer rain.

Mostly here for hiking or beaches: Wait for spring or autumn. Winter Korea is good, but not for that.
