Seoul in Autumn: How October compares
| Category | September | October | November |
|---|---|---|---|
Weather | Warm to mild, around 20–27°C (68–81°F) early, cooler late | Cool and crisp, around 10–18°C (50–64°F) | Cooler, around 4–12°C (39–54°F), with cold nights by month-end |
Crowds | Moderate to high; Chuseok can shift patterns | High; foliage weekends and clear-weather sightseeing push demand up | Moderate early, then lower after the first week |
Atmosphere | Late-summer heat fades, festival energy stays high | Best mix of foliage, walking weather, and clear views | Quieter, more local, and better for museums and food-led trips |
Key events | Chuseok programs, fireworks season, cultural festivals | Seoul Street Arts Festival, Writers' Festival, Halloween, silver grass season | Kimchi events, café shows, performing arts season |
Public holidays | Chuseok can affect business hours and transport | National Foundation Day (Oct 3), Hangul Day (Oct 9) | No major autumn holiday pressure |
Budget | Mixed; holiday windows can spike | Higher, especially Fri–Sun and mid-late month | Softer rates after early November |
Best for | Festival-goers, shoulder-season travelers | First-timers, photographers, walkers, couples | Value seekers, museum fans, food-focused trips |
Book early? | Yes for Chuseok dates and big festivals | Yes for hotels, tours, foliage day trips, and sunset activities | Less urgency outside first-week foliage leftovers |
Transport tips | Chuseok traffic can slow day trips | Start day trips early; use subway for central Seoul on weekends | Easier metro rides and fewer queues at major hubs |
