Seoul Weather in October

October weather in Seoul

October is one of Seoul's best months for being outdoors. Days feel mild, while evenings turn cool; the average high is 19°C and the low is 10°C. Rain falls on about seven days, much less often than in September, so you can fit palace visits and long walks between showers.

Gyeongbokgung Palace and the lanes of Bukchon Hanok Village are comfortable to explore without summer's sticky heat. Autumn colour also makes walks around Namsan lovely. Save a rainy spell for the National Museum of Korea or a bowl of hot kalguksu, a noodle soup.

Crowds and events

The comfortable weather draws plenty of visitors, especially to foliage spots and popular palaces. October is a busy time, so expect more people around Myeongdong and Insadong than in quieter winter months. It's not usually as hot or rainy as summer, but don't expect empty streets or low-season prices.

Hangul Day, a national holiday on October 9, can bring extra local visitors to central Seoul. The Seoul International Fireworks Festival is also often held in October, though its date can vary. Check the year's schedule before making plans around it.

If you hate crowds, visit Gyeongbokgung on a weekday rather than a weekend.

October in Seoul: local tips

For a clear autumn day, walk from Namsan's base up to N Seoul Tower. The slope is easier to enjoy in October's mild weather, and the city views are a good reward. If the evening feels chilly, head back down to Myeongdong for street food and a warm snack.

For palace visits, note that Gyeongbokgung is closed on Tuesdays. You can pair it with Bukchon, but its narrow residential lanes are still busy at popular times. Keep voices low and don't block doorways while taking photos.
