Thinking of spending Christmas in Seoul? Get ready for cold, dry winter weather. Average daytime temperatures sit around 3°C (37°F), while nights can drop to -7°C (19°F). Sometimes it snows, but it’s usually just a light dusting, and the city mostly stays dry with little precipitation.
The air feels crisp, and the skies are often clear, so the city looks bright even on the shortest days. You’ll spot plenty of sunshine despite the cold, which honestly makes strolling through decorated streets and outdoor markets much more enjoyable. If you dress in layers, you can comfortably explore both festive events and local traditions.
There’s more to prepare for than just the weather. From what to wear, to where to find the best festive spots, you’ll discover what makes Christmas in Seoul a unique experience.
Typical Christmas Weather in Seoul
Expect cold days with short daylight hours and fresh, crisp air during Christmas in Seoul. Temperatures often dip below freezing at night, and you’ll notice light snow or dry winter winds pretty often.
Average Temperatures in December
Daytime highs in December usually reach 3–5°C (37–41°F). At night, lows often fall to -3 to -5°C (23–26°F).
It’s one of the coldest months in Seoul, with only January being colder. You’ll feel how quickly the temperature drops after sunset. Even if the day feels manageable, nights can feel much colder, especially with wind chill.
Seoul has a long winter, so you’ll notice a steady decrease in warmth from early December through the holidays. Wearing layers, a warm coat, gloves, and thermal wear is essential if you want to walk around Christmas markets or check out outdoor light displays.
Chance of Snow and Precipitation
Snow might fall in Seoul during December, but it’s not a sure thing. On average, the city gets about 22–25 mm of precipitation for the month, spread over 6–8 days.
Most of this comes as light snow or a mix of rain and snow. Snow cover usually doesn’t last long because there’s less precipitation than in places like Gangwon Province. Still, you might see a dusting of snow that adds to the holiday vibe.
If you’re heading to outdoor attractions, remember that icy sidewalks and slushy streets can pop up after snow. Waterproof shoes with good grip really help, especially in the evenings when melted snow refreezes.
Humidity and Wind Speed
December’s relative humidity averages around 60%, which feels dry compared to Seoul’s sticky summers. The dry air makes the cold feel sharper, so carrying lip balm or hand cream is smart.
Winds tend to stay light to moderate, averaging about 7–10 km/h (4–6 mph), but gusts can feel stronger, especially between buildings. Wind chill can lower the temperature you actually feel.
Indoors, the air gets even drier because of heating systems. Using a small humidifier or just drinking plenty of water helps with that dry winter discomfort.
Daylight, Sunshine, and UV Index
In late December, Seoul goes through short days, limited sunshine, and a low UV index. These conditions shape how much natural light you’ll get and how much sun protection you really need.
Daylight Hours in December
Around Christmas, daylight in Seoul is at its shortest. The sun rises close to 7:45 AM and sets around 5:15 PM.
That’s about 9.5 hours of daylight each day. The limited daylight affects your sightseeing plans. Outdoor activities work best around midday when the sun is highest.
The sun sits low in the sky, so even at noon the light feels softer than in summer. If you’re used to longer days, you’ll notice the early sunset. Plan for evening activities indoors, like dining, shopping, or catching a cultural performance.
Average Sunshine Duration
Even though you get about 9.5 hours of daylight, the actual bright sunshine is less. In December, Seoul averages about 5 hours of sunshine per day.
Skies are often hazy or partly cloudy the rest of the time. Clear skies aren’t guaranteed. Sunshine is most common on cold, dry days when the wind pushes away clouds. Sometimes, the sun only peeks out briefly.
Here’s a quick breakdown:
- Daylight available: ~9.5 hours
- Bright sunshine: ~5 hours
- Cloudy or dim light: ~4.5 hours
Afternoons can feel dim, especially in shaded streets. If you want the best light for photos, aim for late morning to early afternoon.
UV Index and Sun Protection
The UV index in Seoul during December stays low, usually between 1 and 2. At this level, the risk of sunburn is pretty minimal for most people. You can spend time outdoors without heavy sun protection.
If you’re near snow or ice, UV exposure goes up a bit. In those cases, a light sunscreen on exposed skin is still a good idea. Sunglasses help with glare too.
You don’t need strong sunblock or high-SPF products in December. A simple moisturizer with SPF or lip balm with sun protection is usually enough.
What to Wear and Pack for Christmas in Seoul
Temperatures around Christmas in Seoul often hover near freezing. Daytime highs just barely get above 0°C (32°F), and nighttime lows dip well below.
Cold winds can make it feel even sharper, so packing the right clothes and accessories really matters if you want to stay comfortable outside.
Essential Winter Clothing
Bring a thick insulated coat, ideally a long down jacket that covers your thighs. This style blocks wind and keeps you warmer than a short coat. A hood helps too, so you might not even need a scarf.
Layering helps, but you don’t need to overdo it. A thermal base layer, a long-sleeve shirt or sweater, and your outer jacket usually do the trick. Indoors, heating is strong, so wearing fewer inner layers makes it easier to adjust.
Pack warm bottoms like lined jeans or thermal leggings under regular pants. For shoes, bring water-resistant boots with good grip—icy sidewalks are common. Thick socks made of wool or heat-retaining fabric help keep your feet warm.
Accessories like gloves, hats, and scarves are helpful, but you might skip some depending on your cold tolerance. Many locals just use gloves and a hooded coat for daily life.
Tips for Staying Warm Outdoors
Strong winds along the Han River or in open plazas can make the cold feel worse. Pick clothing that blocks wind, like a down coat with a windproof shell.
Keep your hands and ears covered, since they lose heat fast. Touchscreen gloves are handy for maps or transit apps—you won’t need to take them off.
Carrying heat packs is a common trick in Seoul. You can buy disposable ones at convenience stores and slip them into your pockets. They keep you warm for hours.
If you’ll be outside for a while—like at Christmas markets or ice skating—wear layered socks and bring a scarf or neck warmer. These little extras make a big difference if you’re out for long.
Christmas Traditions and Festivities
Christmas in Seoul mixes Western holiday customs with local culture. You’ll see religious observances, romantic outings, and big public displays that make the city feel festive, even though family traditions aren’t as front-and-center as in some other countries.
How Christmas Is Celebrated in Seoul
In Seoul, Christmas is both a public holiday and a commercial event. Some families attend church services, but many people, especially younger couples, treat it as a special date night.
Restaurants book up quickly, so people often make reservations weeks ahead. Gift-giving isn’t as central as in Western countries. You might see small exchanges between close friends or family, but it’s not a big cultural requirement.
The focus leans more on shared experiences, like dining out or enjoying decorated spaces together. Religious celebrations matter for the Christian population. Major churches like Myeongdong Cathedral hold Christmas Mass, including some services in English, which draw both locals and visitors.
These gatherings highlight the religious side of the holiday, while the city’s commercial areas show off the decorative and social side.
Popular Activities and Events
Seoul offers all sorts of seasonal activities in December. Large department stores such as Shinsegae and Lotte host elaborate light shows and holiday window displays.
You can check out indoor Christmas markets where ornaments, sweets, and small gifts are sold. Public spaces transform for the season. The Seoul Lantern Festival lights up Cheonggyecheon Stream and Gwanghwamun Square with colorful displays.
At Seoul Plaza, you can skate outdoors for a small fee and take in views of a big Christmas tree and Deoksugung Palace nearby. Performances add to the vibe too. Ballet companies stage The Nutcracker, and concert halls feature seasonal music.
If you prefer a quieter space, the Starfield Library inside COEX Mall has a massive indoor Christmas tree among its floor-to-ceiling bookshelves.
Best Places to Experience Christmas Atmosphere
You’ll find the most festive holiday settings in Seoul by checking out well-known events and landmarks. These places combine lights, music, and traditions that really show how the city celebrates Christmas.
Seoul Lantern Festival Highlights
The Seoul Lantern Festival happens along Cheonggyecheon Stream, a central spot lined with glowing lanterns. The event usually runs from mid-December into early January, so it’s easy to fit into your plans.
You’ll see lanterns shaped like animals, cultural symbols, and Christmas designs. The displays are big, colorful, and carefully arranged to reflect both winter traditions and Korean artistry.
Walking along the stream in the evening lets you see the lights at their best. Food stalls and small performances often pop up nearby, adding to the fun. It can get crowded, so visiting on a weekday night helps you move around more easily.
Gwanghwamun Square Market
Gwanghwamun Square becomes the place for seasonal markets during Christmas. The area is near Gyeongbokgung Palace, so you can mix sightseeing with holiday shopping.
Market stalls sell winter snacks, hot drinks, and handmade crafts. You’ll also find holiday decorations and small gifts, making it a good stop for souvenirs with a local feel.
The square is decorated with light displays and a central tree, which makes for a great photo backdrop. Since the area is wide and open, dress warmly to block the wind. Early evening is a good time to catch both the market buzz and the lights.
Myeongdong Cathedral Lights and Mass
Myeongdong Cathedral stands out as one of Korea’s most significant Catholic churches, and it becomes a focal point at Christmas. The building glows with white and gold lights that show off its Gothic look.
You can attend Christmas Mass here, which brings together both locals and visitors. Services are in Korean, but the experience feels welcoming no matter what language you speak.
Outside the cathedral, the Myeongdong shopping district adds to the holiday mood with street decorations, music, and festive window displays. If you want both tradition and city festivity, this area gives you both within a short walk.

Most attractions and shops stay open, though some schedules shift a bit. Planning your days around light displays, seasonal markets, and easy transport will help you get the most out of your visit.
Holiday Opening Hours
Shops, restaurants, and cafes in Seoul usually open on Christmas Day, but smaller businesses might close or shorten hours. Major department stores like Shinsegae or Lotte often extend hours for holiday shopping.
Tourist spots such as N Seoul Tower, COEX Mall, and Lotte World generally operate as usual. Public transportation, including subways and buses, runs on a normal schedule, but expect bigger crowds at night.
