Seoul's two beautiful seasons are textbook: April's cherry blossoms along the Yeouido riverside and October's fiery foliage in the palace grounds. Both are genuinely spectacular and both are priced accordingly. The rest of the year has its own arguments — winter's crisp palaces, summer's festivals against a monsoon backdrop.
Our planning summary: September–October is the best window, spring is the blossom race, and the monsoon (late June–July) is the season to plan around. Here's the breakdown.
What this guide covers
The Seasonal Calendar
Seoul by season, compressed.
Day 1
Spring & Summer
Mar–Apr: the blossom window — book early, expect crowds at Yeouido and Seokchon Lake. May: green, warm, festival season. Jun–Jul: monsoon — museums, cafés and malls carry the trip.
Day 2
Autumn & Winter
Sep–Oct: the best month pairing — foliage, festivals, clear air. Nov: late foliage, cooler. Dec–Feb: crisp palaces, jjimjilbang season, ski-day-trip options; Jan–Feb is the value window.
Autumn: The Connoisseur's Choice
Late September to early November combines mild days, clear skies and the foliage show — Namsan, Changdeokgung's Secret Garden and Bukhansan all peak in sequence. October also brings the Busan fireworks-adjacent energy south and Seoul's own festival calendar (Seoul Light, jazz festivals). It's the month locals would pick.
Spring: The Blossom Race
Yeouido's cherry blossoms bloom late March to early April — a two-week window that books hotels months out. The upside over Japan: blossom festivals in every park, and prices that spike less dramatically. May is the sleeper month — warm, green, and festival-heavy without the pollen chaos.
Monsoon and Winter
Late June through July is jangma, the monsoon: humid, gray, and sometimes relentless — plan museum-and-café days and skip the hiking. August is hot but festival-rich (Boryeong Mud Festival, water-gun fights in Sinchon). Winter is genuinely appealing: crisp, dry, snow-dusted palaces, and hot-pot-and-spa weather that locals defend fiercely.
What to know before you go
Booking windows
- Blossom weeks (late Mar–early Apr): 2–3 months ahead.
- October: 6–8 weeks ahead.
- Monsoon season: last-minute deals are common.
Packing notes
- Monsoon: a real rain jacket, waterproof shoes.
- Winter: serious layers — Seoul runs colder than Tokyo.
- Autumn/spring: layers for 10–15°C swings between morning and afternoon.

Typically late March to early April, peaking around Yeouido's festival. The window is about two weeks and shifts yearly with the winter's temperature.
