What To Wear In Korea From October To December

Wear layers. In November, Seoul averages about 12°C in the afternoon and 3.5°C before dawn, so you want a warm jacket over a thin knit, a scarf, and thermals by late month. October still feels like spring (20°C highs), December is real winter (4°C highs, lows below zero). Layers let you strip off indoors, where Korea runs its heating hot.

Sunbae Says: Pack one warm outer layer and zero heavy jumpers. Koreans dress thin underneath and warm on top, because the subway, cafés and restaurants are toasty.

Picture it: you land at Incheon on a November evening and the air outside is a few degrees above freezing. Twenty minutes later you are on a heated train, sweating in the jumper you packed for the cold. Dress for both and you win.

The Numbers: Seoul Month By Month

These are the official 1991 to 2020 averages for Seoul from the Korea Meteorological Administration’s climate normals (in Korean).

Month	Average high	Average low	Rain days	Snow days
October	20.2°C	10.6°C	4.8	0
November	11.9°C	3.5°C	6.4	2.3
December	4.2°C	minus 3.4°C	4.2	6.4

The swing between dawn and afternoon is 8 to 10 degrees in every month. That single fact decides your packing: you will be cold at 8am and warm at 2pm on the same day.

Averages hide cold snaps. Seoul’s record lows are minus 11.9°C in November and minus 23.1°C in December; you won’t see those, but one sharp week is normal.

Now the 2026 reality. September was 1.2°C warmer than normal nationwide with only 17% of normal rain, Money Today reported from the KMA’s monthly review (in Korean). And the KMA’s medium range forecast (in Korean) issued on 4 Oct has Seoul at 25°C highs and 10 to 14°C lows from 8 to 12 Oct, before dipping to 21°C by 14 Oct.

Heads Up: If you land in the second week of October, do not pack only winter gear. Launch week is forecast at T shirt afternoons and jacket mornings, a 15 degree gap. Check the forecast three days before you fly and adjust.

What Koreans Actually Wear By Temperature

Korea has a habit English sites miss: the 기온별 옷차림 (gion byeol otchharim, “outfits by temperature”) chart, which people check before getting dressed. Here is the consensus, drawn from the common Korean chart on Namuwiki and E-Land’s seasonal style guide, mapped to when you will meet each band in Seoul.

Temperature	What Koreans wear	When you will meet it
20 to 22°C	Thin cardigan, long sleeve shirt, jeans	Mid October afternoons
17 to 19°C	Light jacket or windbreaker, sweatshirt	Late October afternoons
12 to 16°C	Jacket, fleece, knit	Early November afternoons, October nights
9 to 11°C	Trench coat, layered tops, thermal leggings	Mid November days
5 to 8°C	Wool coat or leather jacket, scarf, thermals	Late November, early December days
4°C and under	Padded coat, gloves, scarf, thermals	December, and any November morning cold snap

The chart’s smartest footnote: dress for the cold morning too, because the daily low hits around 4am.

Mid To Late October: Light Layers

October is easy: a long sleeve top, a light jacket and jeans. Evenings drop to around 10°C, so carry the jacket after dark. My Seoul in late October guide has what is on that fortnight, and the Seoul autumn foliage guide tells you when the leaves turn.

Heading to the mountains? Dress a level warmer: ridges on Seoraksan are far colder and windier than the city.

November: The Month Most People Underpack

November is the trap. The first week can feel like October; by the last, mornings sit near freezing and a couple of snow days are normal. My Korea in November guide walks you through the month week by week.

My November kit: a warm jacket or knee length padded coat, a thin knit, one thermal top, a scarf and closed shoes. Gloves join after mid month.

[SUNBAE STORY: the first properly cold November morning of a recent year, and what the subway platform looked like when everyone switched to long padding overnight]

December: Proper Winter

December means a real winter coat. The long padded coat (Koreans call it 롱패딩, “long padding”) is the unofficial uniform on the street and the subway, and there is a reason: wind funnels between towers, and 6.4 snowy days a month on average means slush.

Add thermals under your jeans, an ear covering hat and touchscreen gloves for map checks. My Korea in December guide covers the rest of the month, and if you are hitting the slopes, see ski resorts near Seoul and bring your own base layers.

Pick Your Outer Layer

Option	Best For	Cost	Time	My Take
Packable down jacket	October to late November, carry on travellers	Bring your own	Zero	My pick for most trips before December
Knee length padded coat	Late November and December	Bring or buy here	An hour of shopping	Essential from December, overkill in October
Buy everything on arrival	Last minute packers	Varies	Half a day	Fine for thermals and gloves, risky for a coat

My verdict: until late November, a packable down jacket plus a thermal top beats any coat, because it squashes into a day bag the second you walk into a heated café. After that, go long padding.

Shoes, Socks And The Indoor Rule

You will walk far more than you expect, much of it up subway stairs. Grippy sneakers beat fashion boots, and in December go water resistant.

Now the unwritten rule: socks matter. Floor seating restaurants, temples, guesthouses and every jjimjilbang mean shoes off, so holes will be seen. Slip ons save lacing at the door. My unwritten rules of Korea guide covers the rest of the shoes off etiquette.

Floors are often heated (ondol). After 24 winters here, my rule: the best outfit is one whose top layer comes off in two seconds.

Temples And Palaces: What To Wear

Temples. The official Templestay etiquette page asks for dress that is “clean, neat and conservative”: no sleeveless tops, mini skirts or short shorts, and bare feet are not allowed inside. In late autumn that mostly solves itself, because you will be in trousers anyway. For Jogyesa downtown, take Anguk Station (Line 3, orange) Exit 6 and walk about 10 minutes.

Staying overnight? Templestay’s FAQ says temples hand you a vest and trousers, but mountain mornings are cold, so bring a jacket and thick socks. My templestay guide has the full kit.

Palaces. No dress code at all. The deal is hanbok: Visit Seoul’s Gyeongbokgung page says a complete hanbok gets you in free, otherwise foreign adults aged 19 to 64 pay 3,000 won. In November and December it opens 9am to 5pm, last entry an hour before, closed Tuesdays. Take Gyeongbokgung Station (Line 3) Exit 5.

Heads Up: “Complete” is checked. Under the National Heritage Service standard reported by Asia Economy in May 2026 (in Korean), you need a jeogori (jacket) with a chima (skirt) or baji (trousers). A jeogori over your jeans, or a hanbok skirt with a T shirt, does not count.

Where To Buy Cheap Warm Layers In Seoul

Forgot something? Korea is the easiest place in the world to fix a packing mistake.

Option	Best For	Cost	Time	My Take
Convenience store	Hot packs, a cheap scarf or gloves in a pinch	Cheapest	Five minutes	Grab hot packs here, nothing else
Daiso Myeongdong	Hot packs, socks, gloves, fleece bits	Most items 1,000 to 5,000 won	45 minutes	My pick for small warm stuff
GOTOMALL	Knits, coats, scarves at underground mall prices	Budget	Two hours	My pick for a coat or knitwear
Namdaemun Market	Hats, gloves, thermals, outdoor gear	Budget, haggle politely	Two hours	Best for a market morning plus shopping

Convenience stores. GS25, CU and 7 Eleven stock hot packs once it turns cold. The CU in Incheon Terminal 1 arrivals runs 24 hours.

Daiso Myeongdong. Twelve floors, a few minutes’ walk from Myeong-dong Station (Line 4, sky blue), open 10am to 10pm. Sources disagree on Exit 1 or 2, so check Naver Map for the exit.

GOTOMALL. The giant mall under Express Bus Terminal. Per GOTOMALL’s own access guide, use Exit 8-1 or 8-2 from Line 3 (orange), Exit 8 from Line 7 (olive), or Exit 8, 8-1 or 8-2 from Line 9 (gold). It runs 10am to 8pm every day of the year.

Namdaemun Market. Take Hoehyeon Station (Line 4) Exit 5; the Namdaemun Market Tourist Information Center is 80 m from the exit, open 10am to 7pm, with English help. Go in daylight; stall hours vary.

Offers Worth Knowing

At participating tax free shops, foreign visitors get an immediate refund at the till on purchases from 15,000 won to under 1,000,000 won each, up to 5,000,000 won per trip, per Visit Seoul’s tax refund guide (see Resources). Bring your passport.

What Locals Know

Koreans switch wardrobes in one weekend. When minimum temperatures fell into single digits on 19 October 2025, GS25 saw hot pack sales jump 587.3% on the week before and winter accessories 257.3%, per Digital Chosun (in Korean). One cold Sunday and the city is in padding by Monday.

Watch for “수능 한파”. Koreans joke that the national university entrance exam always brings the first real cold, the “Suneung cold snap”. This year’s exam is on 19 November, per the Ministry of Education notice (in Korean). Folklore, not a forecast, but carry your warm layer that week.

Thermals have Korean brand names. Uniqlo’s Heattech is the famous one, but Korean rivals have sold their own lines, such as Topten’s OnAir, SPAO’s Warmtech and BYC’s Bodyheat. Ask any clothing shop for 발열내의 (bareol naeui, heat generating underwear).

Pick Your Version

If It’s Your First Time

You will overpack. I’d bring one warm outer layer, three thin layers and comfy shoes, then buy anything missing on day two. Start with my first timer hub for the rest of your prep, and sort your transit card before you go shopping across town.

If You’re Bringing Kids

Children lose gloves at a spectacular rate, so pack cheap spares and top up at Daiso. Zip layers they can remove themselves on the subway save meltdowns.

If You’re Travelling Solo

You carry everything all day. I’d choose a packable down jacket and one pair of shoes that works for a palace at 9am and a bar at 11pm.

If You’re Here For A Reset

Bathhouses and temple stays mean shoes off and warm floors. Pack soft layers you can sit cross legged in. This is general information, not medical advice: if you have a heart condition or high blood pressure, check with your doctor before hot baths after a cold walk.

Sunbae’s Picks

My one must pack item: a thin thermal top. It weighs nothing and turns a light jacket into a November jacket.

If I only had one coat for a mid November trip, I’d bring a knee length padded coat, not a wool one. It shrugs off drizzle and wind.

Worth It: a lightweight packable down jacket. It comes off in the café and back on at the bus stop.

Skip It: a thick wool jumper. You will sweat on the subway and have nowhere to put it.

Air Quality: Pack A Few Masks

Seoul runs a seasonal fine dust programme every December to March, because 91% of recent high concentration days fell in those months, per its clean air portal. Check AirKorea or your weather app before a long outdoor day, and buy KF94 masks at any pharmacy or convenience store. This is general information, not medical advice; if you have asthma, bring your usual medication.

What’s Changing In 2026

Autumn is running warm. September 2026 was the sixth straight year of an above normal September, and the KMA’s late August three month outlook leaned warmer than normal through November, with a 60% chance of an above normal November in its Daejeon and Chungcheong breakdown, Newspim reported (in Korean). My read: October may feel like late summer, but warm autumns still bring sharp cold snaps. Pack the thermal anyway.

A Quick Packing List

• Warm jacket or padded coat (November and December)
• Two or three thin knits or fleeces
• One or two thermal tops and leggings (late November and December)
• Scarf, beanie, touchscreen gloves
• Grippy walking shoes, ideally slip on
• Good socks, no holes
• A few KF94 masks
• Lip balm and hand cream for dry air

Word Of The Stop

내복 (naebok): thermal underwear. Korean grandparents swear by it, and so do I. Ask for it in any clothing shop from November onward.

How I Checked This

On 4 October 2026 I rechecked Seoul’s averages against the KMA’s 1991 to 2020 normals, read that morning’s KMA medium range forecast and Korean reporting on September’s climate and the seasonal outlook, and verified exits and hours on GOTOMALL’s and Visit Seoul’s pages. Temple and palace rules come from Templestay, Visit Seoul and Korean reporting. I could not find the KMA’s October to December outlook, Daiso’s exit is unconfirmed, and nobody can forecast cold snaps, so check the KMA before you fly.
