Seoul in November: 12°C / 54°F afternoons, 3°C / 37°F nights, about 8 rain days, and the steepest drop of the year.
Pack for the whole slope, not the average. NOAA's daily record for the Korea Meteorological Administration's Seoul station puts November at 11.8°C by day and 2.8°C at night, with about 59mm of rain over 8 days. Those averages hide the fastest fall of Seoul's year: afternoons average 15.2°C in the first ten days and 8.9°C in the last ten, and nights slide from 5.5°C to 0.4°C, with frost on about 9 of them. A trench handles the start and fails the finish. So build on a camel wool coat, give it a thin down liner for the last week, add a turtleneck for the frost mornings and one colour for the ginkgo. On Thursday 19 November the country sits its university entrance exam, and on exam day in 2024 every take-off and landing in Korea stopped for 35 minutes during its English listening test.
Seoul's November starts in a trench and ends in down. The first ten days average 15°C, the last ten 9°C, and the coat has to cover both.

Start with a coat that works at 15°C and still works at 3°C with help. A hip-length camel wool coat goes open over the turtleneck in the first week and buttoned over the down liner in the last, and hip length keeps it clear of the subway seat and the café chair in Seongsu. Camel is the warm note in a capsule of black, cream and pale grey.

This is the piece that moves the coat from autumn to winter. Nights fall from 5.5°C to 0.4°C across the month, and a thin collarless down liner under the camel coat adds the warmth of a padded jacket without its bulk. Snap it on for a 7am palace gate and roll it into the bag by an afternoon in Hannam-dong.

Frost arrives on about 9 November nights, and a turtleneck covers your neck on those mornings so the scarf can stay loose. Cream rather than October's black, so the pale half of the capsule has a centre, and fine rib so it sits flat under the liner.

A pressed pleat and a wide leg read precise in Hannam-dong, and the width leaves room for a thermal legging in the last, coldest week without showing a line. Pale grey is the light half of the capsule, and it keeps a camel coat from looking like an office.

Polished black derbies, because Seoul reads shoes first and November gives you about 8 wet days to scuff them. Leather keeps your feet dry on a cold wet pavement where canvas soaks through, and a lace-up stays put on the long walk from Gyeongbokgung up to Samcheong-dong.

One colour, the Seoul way, and in November it comes from the trees along the avenues as the ginkgo turns. A marled mustard wool scarf closes the neck of the coat at 3°C / 37°F and gives a camel-and-grey outfit a point to look at.

Structured, because a soft bag sags by evening and Seoul notices. Cognac with a top handle and a strap sits with the camel coat, takes the down liner rolled small when it comes off at lunch, and goes across the body on a crowded Line 2 train.

Your second pair of trousers, for a day on your feet. Clean dark indigo, unripped and hemmed at the ankle, is as far toward casual as the Seoul register goes, and heavy denim blocks more of a cold wind than it looks. Wear them with the turtleneck and derbies for a Bukchon walk.
Cream turtleneck · pale grey trousers · black derbies · camel coat open · cognac bag. Gyeongbokgung at nine, Samcheong-dong and a Bukchon lane on foot, lunch in Anguk.
Down liner under the camel coat, buttoned · cream turtleneck · dark indigo jeans · derbies · mustard scarf. The Han at Banpo after dark with frost on the way, then dinner in Hannam-dong.
A suggested look — camel wool coat, cream fine-rib turtleneck, pale grey pleated wide-leg trousers, black leather derbies, mustard wool scarf.
NOAA NCEI's daily record for Seoul (KMA station 108, 30 Novembers from 1991 to 2020) gives an average high of 11.8°C and a low of 2.8°C, with about 59mm of rain across 8 days of 1mm or more. No month in that record cools faster: afternoons average 15.2°C in the first ten days and 8.9°C in the last ten, and nights fall from 5.5°C to 0.4°C, with frost on about 9 of them. Daylight shrinks from about 10 hours 35 minutes on 1 November to 9 hours 45 minutes by the 30th.
A camel wool coat, a thin black down liner, a cream wool turtleneck, pale grey pleated wide-leg trousers, dark indigo straight jeans, black leather derbies, a mustard wool scarf and a structured cognac bag. The coat and turtleneck cover the first half of the month; add the liner once nights reach freezing in the last week. Leave the trench, the full-length padded coat and the canvas sneakers at home: each suits about ten days of the month and fails the rest.
Yes. The 2027 College Scholastic Ability Test, Korea's university entrance exam, is on Thursday 19 November 2026, the Ministry of Education says. The country makes room for it: on exam day in 2024 every take-off and landing in Korea stopped from 1:05 to 1:40pm for the English listening test, and 156 flights were retimed. The 2026 arrangements are announced closer to the date, so check your flight time with the airline if it falls on the 19th. Frost mornings are common by then, so wear the liner under the coat if you are out early.
Early, unless you want the first taste of winter. NOAA's record averages 15.2°C by day and 5.5°C at night across the first ten days, which is still knit-and-coat weather, and the last of the autumn colour is on the trees. By the last ten days afternoons average 8.9°C and nights 0.4°C, and the city has moved into padded coats. The entrance exam falls in between, on Thursday 19 November.
November is about eight degrees colder by day and seven at night: NOAA's record for the same station gives October 20.1°C and 9.9°C and November 11.8°C and 2.8°C. Rain barely moves, 61mm against 59mm, but frost arrives, on about 9 November nights against almost none in October. Our October guide builds on a stone trench; November keeps a wool coat and adds a down liner, because a trench runs out of warmth in the second half of the month.
Precise, and more padded by the week. The November street in Hannam-dong and Seongsu is a wool coat or a short padded jacket over a knit, straight or wide trousers with a crease, polished shoes and a structured bag, with one colour doing the talking. By the last week the long padded coat appears, a style Korea JoongAng Daily traces to 1994 and a peak in 2017. Musinsa, the Seoul fashion platform, began in 2001 as "a house of sneaker photos," an online community started by a high school student who loved sneakers.
