October is the month to be in Busan. The Busan International Film Festival turns the city into Korea’s cultural capital for two weeks, the summer beach crowds are gone, and the weather is the finest of the year. Here is everything you need to know.
Quick answer: The best things to do in Busan in October are the Busan International Film Festival (BIFF, early to mid-October), Gwangalli Beach evening walks with the illuminated bridge at its best in clear autumn air, Haedong Yonggungsa Temple in morning light, the Gamcheon Culture Village before the crowds return, and Jagalchi Market’s autumn seafood. October temperatures of 16 to 22 degrees are the most comfortable of the year.
Busan Weather in October
October is consistently cited as Busan’s finest month for weather. Average temperatures of 16 to 22 degrees Celsius are warm enough for outdoor activity without the exhausting heat and humidity of summer. Clear days are the norm. The sky has the particular brightness of Korean autumn, making outdoor photography excellent throughout the day, rather than only in the golden hours. Evenings drop to 1- 14 degrees by late October, requiring a light jacket.
Busan International Film Festival (BIFF)
The Busan International Film Festival, established in 1996, is Asia’s largest film festival and one of the most significant in the world for Asian cinema. The festival runs for approximately 10 days in early to mid-October (dates vary by year; check the official BIFF website for 2026 dates).
The hub of festival activity is the BIFF Village at Haeundae Beach and the CGV and Lotte Cinema multiplexes in the Haeundae and Nampo areas. Hundreds of films from dozens of countries screen across the city. Many screenings are open to the public with same-day or advance tickets (5,000 to 15,000 won per film). The outdoor screenings at Haeundae Beach, with the sea as backdrop, are particularly atmospheric. Korean and international directors attend Q&A sessions after screenings. Celebrity red-carpet events attract large crowds at the opening and closing ceremonies.
Even if you have no interest in cinema, BIFF transforms the energy of the city during its run. The streets around Haeundae and the Nampo BIFF Square fill with film-related events, food stalls, and the general excitement of an international cultural event. Worth being in Busan regardless.
Beaches Without the Crowds
October’s most practical benefit for beach lovers: Haeundae and Gwangalli beaches have the summer crowd gone, but the water is still warm enough for walking, and the sand is accessible. The Haeundae beachfront promenade and the Dongbaekseom Island coastal trail are at their most pleasant for walking, with clear views, comfortable temperatures, and no July to August umbrella-to-umbrella crowds.
Gwangalli Beach in October evenings, with the Gwangan Diamond Bridge lit against a clear autumn sky, is one of Busan’s finest scenes. Restaurants along the promenade have tables outside again.
Autumn Food Culture
October is peak season for several Busan seafood specialties. The Jagalchi Fish Market in October has outstanding crab (대게 daege, snow crab, and 꽃게 kkotge, blue crab) as the autumn catch comes in. A full daege crab at Jagalchi or a restaurant near Haeundae: 40,000 to 80,000 won per crab, depending on size.
The Millak Raw Fish Town near Gwangalli Beach is a multi-story raw fish complex where vendors prepare fresh sashimi from the day’s catch. October fish quality is excellent, and prices are lower than the summer peak season.
Haedong Yonggungsa in October Morning Light
The coastal temple north of Haeundae is always worth visiting. Still, on an October morning with a clear sky, moderate temperature, and the East Sea reflecting strongly, it is particularly atmospheric. The 20-minute walk from the bus stop down to the temple, through coastal pines and along the stone stairway over the sea, is one of Korea’s finest short walks. Free entry. Arrive by 8 am for the quietest experience.
Practical Notes for October in Busan
BIFF accommodation: Book accommodation 2 to 3 months ahead if your visit overlaps with the film festival. Haeundae hotels fill first. Seomyeon and Nampo-dong are slightly easier and less expensive.
What to wear: Light layers for days, a jacket for evenings. October weather is stable and predictable.
