Korea in December: Winter Weather, Christmas Lights & What to Wear
December is when winter truly settles into Korea.
The trees are bare. The air becomes sharper. The sun disappears earlier, and by evening, you may find yourself walking faster simply because standing still feels too cold.
And yet, December rarely feels completely bleak.
As the temperature drops, Seoul seems to compensate with light.
Department stores glow after dark. Christmas trees appear inside malls and hotels. Cafés feel warmer. Ice rinks begin to open. Streets that looked ordinary a few weeks earlier suddenly sparkle with winter displays.
December in Korea is cold.
But it can also feel surprisingly warm — just in a different way.
DMS verdict: ⭐⭐⭐⭐
Best for: Christmas lights, winter city atmosphere, cafés, shopping, ice skating and travelers who genuinely enjoy cold weather
Think twice if: You dislike freezing temperatures or expect reliable snow throughout your trip

What Is the Weather Like in Korea in December?
December is the beginning of Korea’s proper winter.
In Seoul, temperatures regularly fall below freezing, particularly at night and in the morning. The air is generally dry, and clear blue winter skies are common between colder spells. Seoul’s official tourism guide similarly describes Korean winters as cold, windy and dry, but often accompanied by clear skies.
One thing travelers sometimes misunderstand is snow.
Yes, it can snow in Seoul in December.
No, you should not plan your entire trip assuming Seoul will look like a snow globe.
Snowfall varies from year to year, and even when it does snow, it may melt relatively quickly in the city.
So I would treat December snow as a lovely bonus rather than a guarantee.
Early December vs. Late December
Early December can sometimes still feel like the transition into winter. Cold, yes — but not necessarily the deepest cold Korea can produce.
Late December feels unmistakably wintry. Nights are colder, winter coats become standard, and the Christmas and year-end atmosphere reaches its peak.
And once the sun goes down?
That is when December really changes.
What to Wear in Korea in December
This is no longer light-jacket weather.
By December, I would pack for winter rather than trying to stretch an autumn wardrobe.
A practical outfit looks something like:
thermal or warm base layer → sweater/fleece → winter coat
Add:
- scarf
- gloves
- warm socks
- comfortable closed shoes or boots
- lip balm and moisturizer
A padded coat (padding, as Koreans usually call it) becomes increasingly common as temperatures fall.
And don’t underestimate the difference between walking at 2 p.m. in sunshine and standing outside at 8 p.m.
The temperature on your weather app may not look terrifying.
The wind hitting your face while you wait to cross a huge Seoul intersection may have a different opinion. 😂
December Gets Dark Early — and Seoul Lights Up
This may be my favorite thing about December in Seoul.
Winter takes away the leaves and daylight — and the city answers with lights.
By late afternoon, department stores, hotels, malls and public spaces begin glowing with enormous Christmas displays and media façades.
The area around Myeong-dong is especially famous for this. Shinsegae and Lotte department stores have become popular winter-night stops because of their elaborate seasonal displays. Seoul’s official tourism guide regularly features these areas as part of the city’s Christmas atmosphere.
And these aren’t tiny decorations hanging above a doorway.
Sometimes an entire building becomes Christmas.
You don’t necessarily have to shop.
Grab something warm, walk around after sunset and look up.
Ellie’s note:
December Seoul is one of those rare cases where the early sunset actually works in your favor.
Christmas in Korea: Familiar, but a Little Different
Christmas is very visible in Korea.
Trees, cakes, gifts, lights, Christmas music, hotel displays and seasonal menus appear everywhere.
And December 25 is an official public holiday in Korea.
But the feeling can be a little different from Christmas in countries where it is primarily a major family holiday.
For many Koreans, Christmas can also feel like a date night, outing or seasonal celebration — dinner somewhere nice, seeing the lights, exchanging gifts, taking photos or simply enjoying the atmosphere around the city.
That makes December particularly fun for travelers.
You don’t have to participate in any specific tradition to feel the season.
Sometimes you just walk into a department store and suddenly—
CHRISTMAS.
😂🎄
One of My Favorite December Experiences: Ice Skating
There is something about an outdoor skating rink in December that makes the cold feel intentional.
Instead of fighting winter, you’re finally using it.
Seoul usually operates seasonal outdoor ice rinks, including the well-known Seoul Plaza rink in front of City Hall. Dates vary each year, so always check the current season before visiting; for example, the 2025–26 rink operated from December 19 through February 8.
And at night, with lights reflecting on the ice?
That’s the version of winter I like.
Cold fingers.
Cold nose.
Warm drink afterward.
Worth it.
The Best Part Comes After You Get Cold
This photograph is old.
And I love it for exactly that reason.
Korean winters have changed around me over the years — cafés changed, neighborhoods changed, Christmas decorations became bigger and screens became brighter.
But this feeling hasn’t changed much.
You walk outside until your hands get cold.
Then you step inside.
Your glasses might fog up. Your coat suddenly feels too warm. You wrap both hands around a hot mug.
And for a few minutes, doing absolutely nothing feels wonderful.
I think winter makes warmth more noticeable.
Maybe that’s why December memories tend to stay with me.
What to Do in Korea in December
1. Go Out After Dark
December is one month when I wouldn’t rush back to the hotel after sunset.
Quite the opposite.
Walk through Myeong-dong, central Seoul, Cheonggyecheon or Gwanghwamun and see what the city has put up that year.
Seasonal events change, which is important when planning a future trip. In recent winters, Seoul has hosted large-scale light displays, lantern festivals and Christmas markets around areas such as Cheonggyecheon and Gwanghwamun.
Check the current year’s dates before building your itinerary around a specific event.
The decorations change.
The December feeling doesn’t.
2. Eat Somewhere Warm and Busy
Here’s something photographs of Korean winter sometimes miss:
the sound.
Doors opening.
People squeezing into restaurants.
Steam rising from food.
Neon signs everywhere.
Someone saying “춥다, 빨리 들어가!” — “It’s cold, hurry, let’s go inside!”
😂
December makes warm Korean food even better.
This is the month when I naturally want gukbap, seolleongtang, kalguksu, hot pot, jjigae, fish cake broth, roasted sweet potatoes — basically anything capable of producing steam.
A winter evening doesn’t always need an attraction.
Sometimes dinner is the attraction.
3. Let Seoul Be Ridiculously Festive
Korea is not subtle about seasonal displays anymore. 😂
Hotels, malls, department stores and entertainment complexes compete for attention with enormous trees, immersive screens and elaborate installations.
Some are elegant.
Some are cute.
Some are gloriously over the top.
Go enjoy them.
Especially if it’s freezing outside.
4. Use Indoor Seoul
This is an underrated December strategy.
Don’t design an itinerary that requires you to be outdoors for ten consecutive hours just because you’re traveling.
Korea makes indoor-outdoor travel incredibly easy.
Museum → café → palace → department store → dinner → Christmas lights.
Warm up.
Go back out.
Warm up again.
There is no prize for suffering. 😂
A good December itinerary should move with winter rather than fight it.
Will It Snow in Korea in December?
Possibly.
But please don’t book a December Seoul trip solely because you want snowy photographs.
Snow is not guaranteed on the days you’re visiting.
If seeing substantial snow is one of your main priorities, ski resorts and mountainous areas generally give you better odds than central Seoul.
For Seoul itself:
Christmas lights? Plan for them.
Cold weather? Definitely plan for it.
Snow? Hope for it. ❄️
That’s the safest way to approach December.
What to Eat in Korea in December
December is prime warm-food weather.
Look for:
Gukbap (국밥) — rice and hot soup, simple and deeply satisfying
Seolleongtang (설렁탕) — milky ox-bone soup
Kalguksu (칼국수) — warm knife-cut noodles
Eomuk (어묵) — fish cake, especially good with hot broth at street stalls
Bungeoppang (붕어빵) — warm fish-shaped pastries usually filled with red bean or other fillings
Hotteok (호떡) — sweet pancakes served piping hot
My rule for Korean winter food is very sophisticated:
If steam is coming out of it, investigate.
😂
Is December a Good Time to Visit Korea?
Yes — for the right traveler.
December is not Korea at its most comfortable.
If your dream trip is long outdoor walks in mild weather, I would choose April, May, October or perhaps early November instead.
But December offers something those months don’t.
The contrast.
Cold streets and warm restaurants.
Bare trees and sparkling buildings.
Dark evenings and glowing cafés.
A freezing walk followed by hot soup.
December asks a little more from you physically, but the season gives the city a completely different personality.
And if you love Christmas?
I think you’ll have fun here.
Ellie’s December Note 🤍
Looking through these December photographs while writing this brought back more than I expected.
Some were taken years ago.
Some are recent.
The decorations changed. The cameras got better. Seoul became brighter and more elaborate.
And somewhere between those photographs, life happened.
That’s one of the strange things about keeping pictures of seasons.
At the time, you’re only photographing a Christmas tree, a cup of something warm, or some lights you thought were pretty.
Years later, you realize you were also photographing your life at that moment.
Maybe that’s why I like December.
The year is almost over. Winter has arrived. Everything outside tells us to hurry home and stay warm.
But the city turns on its lights anyway.
So put on a warm coat.
Go outside for a little while.
Eat something hot.
Look at the lights.
Take the photograph.
Those ordinary December nights may become memories before you realize it.
FAQ: Korea in December
Is December very cold in Korea?
Yes. Seoul regularly experiences below-freezing temperatures in December, particularly in the mornings and evenings. Pack proper winter clothing rather than relying only on layers meant for autumn.
Does it snow in Seoul in December?
It can, but snow is not guaranteed during a particular visit. Don’t build your trip around the assumption that Seoul will be covered in snow.
Is Korea good for Christmas?
Yes, particularly if you enjoy Christmas lights, cafés, shopping districts and seasonal displays. Seoul’s major commercial areas become especially festive in December.
Is Christmas a public holiday in Korea?
Yes. December 25 is an official public holiday.
What should I wear in Korea in December?
Bring a proper winter coat, warm layers, gloves, scarf, warm socks and comfortable closed shoes. If you plan to spend evenings outdoors looking at lights, dress warmer than you think you’ll need.
Is December a good month for first-time visitors?
It can be excellent if you enjoy winter and Christmas atmosphere. If weather comfort and long outdoor sightseeing days are more important, spring or autumn would generally be easier.
The Bottom Line
December is cold.
Sometimes very cold.
But I don’t think that’s the whole story.
Korea in December is also hot soup, warm cafés, glowing streets, giant Christmas trees, ice skates, winter coats and people hurrying through the cold toward somewhere warm.
Winter closes the year quietly. Seoul doesn’t.
And maybe that’s exactly what makes December beautiful.
