Read South Korea as a April, May, September & October / July & August pair, not as a slogan season.
Festivals are culture and a price. Lock stays before Seollal.
Windows
- April, May, September & October — The default window for South Korea is April, May, September & October — the weather-crowd compromise.
- July & August — Treat July & August as skip-or-justify months; school holidays, heat or rain often stack here.
- Shoulder — The weeks on either side of peak often buy the best feel-per-price. Read the yellow band on the heatmap.
- Hemisphere — Northern-hemisphere clock is the default; flip months for southern destinations.
Festivals
- Seollal — Seollal lands in February — transport and beds move together. Lock dates first.
- Cherry weeks — Cherry weeks lands in April — transport and beds move together. Lock dates first.
- Buddha birthday lanterns — Buddha birthday lanterns lands in May — transport and beds move together. Lock dates first.
- Chuseok — Chuseok lands in September — transport and beds move together. Lock dates first.
Crowd tips
- Weekdays — Weekday mornings still breathe in temples and museums compared with local weekends.
- Dawn — Dawn slots separate honeymoon photos from cruise tenders.
- Festivals — Festival weeks are culture, not quiet. Sometimes stay outside the festival postcode.
- Ships — Port towns peak at midday. Push the itinerary to morning and evening.
Months in South Korea are a heatmap, not a slogan.
