This Week in Seoul: 5–11 October 2026

The week opens cool and ends almost summery. Monday starts at 19 °C with a slight 20 % rain chance, then skies clear and highs climb steadily — 20, 22, 24 and 25 °C from Tuesday through the weekend, with nights holding around 10–13 °C. No holiday, no washout, no heat. The one thing not to miss: Saturday 10 October, when the Eoseuleong Festival takes over Sangsu-dong's café streets from 14:00 to 21:00 while the Heojun Festival fills Seoul Botanic Park out in Magok. If you only pick one evening to be outside, make it Saturday.

• Weekend outdoors: a single t-shirt is enough during the day with 25 °C highs; carry a thin layer for after sunset.
