Busan Weather in October

Cool days by the sea

October feels mild in Busan, with highs around 21°C and cooler evenings near 14°C. Rain is lighter than in September, though showers can still interrupt a beach day. You'll get comfortable weather for walking around Gamcheon Culture Village, exploring Jagalchi Market or taking the coastal path at Igidae.

Haeundae and Gwangalli are still lovely for a seaside stroll, but the water may feel chilly. For hikers, autumn is a good time to tackle the trails on Geumjeongsan without summer's heat.

Film nights and autumn crowds

The Busan International Film Festival usually brings screenings and industry events in October, especially around Centum City and Haeundae. The Busan Fireworks Festival is also often held in autumn, though its date can vary. Chuseok, South Korea's big harvest holiday, sometimes falls in October; when it does, expect more domestic travel.

Families who want easier beach walks and outdoor sightseeing will likely enjoy October more than the hot, wet summer months.

Costs and local tips

October is one of Busan's most popular months, so don't expect the quietest streets or the lowest hotel rates. It's generally less expensive than peak summer, but prices can rise around film festival dates, especially near Centum City and Haeundae. November is cooler and drier, and often a calmer choice.

For a practical local tip, take the seaside walk from Haeundae toward Dongbaekseom Island. The path gives you sea views without needing a beach swim, and it's an easy way to reach the Nurimaru APEC House. If rain rolls in, duck into Jagalchi Market for a warm bowl of dwaeji gukbap, a pork-and-rice soup.
