Busan in October Rain drops off sharply and the air dries out, which starts the best season for walking the city. The Busan International Film Festival usually runs for ten days in early October around the Busan Cinema Center in Haeundae, though the 2025 edition was held in September. Late typhoons are rare, but Chaba hit Busan in early October 2016.
Afternoons reached 23°C and nights settled at 15°C, warm enough to linger over lunch outdoors. Showers came now and then, about 4 rain days in all, and most of the month stayed dry. October was bone dry in 1 of 20 years, yet 2024 brought 11 rain days.
Each rainy day brought about 24 mm, closer to downpours than drizzle.
How long it rained On a rainy day it rained for about 6.4 hours. Rain came at any time of day.
