Weather in Seoul in November
South Korea · 20-year averages, November
Shoulder season. November sits in between. You will get good days and you will lose some. Highs sit at 10.9 °C and the day is short; this is an indoors-with-excursions month, not an outdoors-all-day one.
November ranks 7 of 12 in Seoul: past the worst of the year but short of May, which is the month to book if the dates are open.
Rain on 7 days, 1 of them heavy. Enough to need a plan B, not enough to need a plan around it. Layers, and a genuinely waterproof outer — at 10.9 °C the difference between a good day and a miserable one is entirely down to what you are wearing.
What the averages hide
Averages flatten a month, and this one hides a few things: 8 nights fall below freezing. Across the twenty years measured, the hottest November day reached 21.4 °C and the coldest night fell to -5 °C, and the wettest single day dropped 39 mm — roughly 83% of the month's rain in one day.
November is moderately variable: 13 mm in the driest year against 128 mm in the wettest, around an average of 47 mm. Roughly two Novembers in three land near that average, and the third does something else entirely.
Wind is light at 11.1 km/h, so the temperature on the page is close to the temperature on your skin, and humidity runs at 75%, which at 10.9 °C means damp rather than muggy — the kind of cold that gets into a coat and stays there.
How November sits in the year
The month is on the way down: 7.8 °C cooler than October, with December dropping another 8 °C. The first week and the last are not the same trip.
Daylight in November
November sits at the dark end of Seoul's year — 10.2 hours of daylight against 14.7 at midsummer, losing 0.9 hours across the month. Sightseeing days are genuinely shorter, and an itinerary built for summer will not fit.
An inland climate
With no coast nearby, the year swings a fair way — 35.2 °C between the warmest afternoons and the coldest nights, wider than any coastal city at this latitude would manage.
How busy it gets
Shoulder. The value months — prices ease off and you get the place closer to itself.
Crowd levels are estimated from climate desirability and school-holiday calendars, not from visitor numbers.
November in Seoul versus nearby
If Seoul is one option among several, the nearby comparison is worth making. Daegu is a better bet in November — 2.3 °C warmer, 2 days less rain. Gwangju is a better bet in November — 2.8 °C warmer, 1 day less rain.
So: November is a compromise. May is 25 points better and is what Seoul is actually like at its best — worth moving the trip for if that is possible, and worth adjusting expectations for if it is not.
