Seoul weather in October
“Mild and bright — an underrated time to visit.”
Roughly 7 rainy days across the month, on average.
October transforms Seoul into one of Asia's most pleasant destinations. Expect average highs of 18.5°C (65°F) and lows of 9.2°C (48°F)—crisp, comfortable autumn weather ideal for exploring outdoors. Rainfall averages 75.4mm across about 6–7 rainy days, so brief showers are possible but won't dominate your itinerary. With 8.3 sunshine hours daily, you'll enjoy plenty of clear skies for sightseeing.
October is peak autumn season in Seoul, when temperatures encourage wandering through historic palaces like Gyeongbokgung and hiking in nearby mountains ablaze with fall foliage. The city's cultural calendar remains active with local festivals and food events. Crowds are moderate—busier than summer but less intense than spring cherry blossom season—making it an ideal sweet spot for travelers.
For 2026, October remains one of Seoul's best-value travel months. Book accommodation early as autumn popularity has grown, but prices remain reasonable compared to peak seasons. Pack layers to handle temperature swings between sunny afternoons and cool mornings and evenings.
The city is split by the Han River and the neighborhoods have deep rivalries — Gangnam is nouveau-money, Gangbuk (Jongno, Ikseon-dong) is old-money and old-Seoul. Naver Maps works, Google Maps doesn't (Korean law blocks foreign mapping). Order at pojangmacha street tents late night in Jongno for sundae blood sausage and soju. The escalator etiquette is stand right, walk left, but on Seoul subway it's stand both sides — a Busan person will get annoyed.
