Smart Traveler’s Calendar: Best Time to Visit Korea (Avoiding Peak Holidays)
The best time to visit Korea is spring or fall — but which one depends on what you’re there for, and which dates you’re accidentally booking around. Here’s the full breakdown.
When Is the Best Time to Visit Korea?
Spring (March to May)
Cherry blossoms start in late March on Jeju Island and in southern cities like Busan, reaching Seoul around the first or second week of April. The Yeouido Cherry Blossom Festival draws crowds, but the timing is worth it. Temperatures run 10–20°C — light jacket in the morning, comfortable by afternoon. Spring is consistently the most recommended best time to visit Korea, and for good reason: the weather cooperates and the scenery delivers.
Fall (Late September to Early November)
Foliage peaks from mid-October to early November. Bukhansan, Namsan, and Seoraksan (an easy day trip from Seoul) all put on a proper show. Temperatures mirror spring — crisp mornings, warm afternoons, no humidity. Many travelers consider this the single best time to visit Korea. The catch: Chuseok falls somewhere in this window every year. Check the exact dates before you book.
Summer (June to August)
Not the most popular time to visit Korea, but not a write-off either. Korea’s rainy season (장마) typically runs from late June to late July typically runs from late June to late July — daily rain, sometimes heavy. August is hot and humid, pushing 33°C on bad days. That said, the Han River Fireworks Festival and other summer events run through the season, and air conditioning is genuinely everywhere. If you’re heat-tolerant and flexible, it’s workable.
Winter (December to February)
Cold and dry. Seoul drops to around -5°C in January. Ski resorts — Vivaldi Park (about 90 minutes from Seoul) and High1 — fill up on weekends. The city has a different energy in winter: street food stalls, heated indoor spaces, and ondol floors that make coming inside genuinely pleasant. Not the best time to visit Korea for outdoor sightseeing, but perfectly fine if you plan around it.
Dates to Watch
Korea’s two major holidays — Seollal (Lunar New Year, usually late Jan/early Feb) and Chuseok (Korean Thanksgiving, usually Sep/Oct) — are the two dates that can genuinely disrupt a trip if you’re not prepared.
During both:
- Highways jam. Travel times double or triple.
- KTX and buses sell out weeks in advance.
- Local restaurants and smaller shops close, especially outside tourist areas.
If your dates overlap, you can still have a good trip — but adjust expectations. Large supermarkets (E-Mart, LOTTE Mart) generally stay open. Convenience stores (CU, GS25, 7-Eleven) are 24/7. Avoid renting a car during these periods if you can help it.
What Stays Open
Major palaces typically run special holiday programming — Gyeongbokgung and others are usually worth visiting for exactly this reason. Myeongdong and Hongdae stay mostly operational. National museums are generally open.

If you’re traveling domestically during either holiday, book KTX the moment tickets go on sale.
Other Public Holidays
Beyond Seollal and Chuseok, Korea has several single-day public holidays. These don’t cause mass closures, but expect busy parks and attractions, and higher hotel rates if they land on a Friday or Monday.
- Independence Movement Day — March 1
- Children’s Day — May 5
- Memorial Day — June 6
- Liberation Day — August 15
- National Foundation Day — October 3
- Hangeul Day — October 9
- Christmas Day — December 25

The Short Version
Spring and fall are the safe bets — both earn the title of best time to visit Korea depending on what you prioritize. Avoid Seollal and Chuseok unless you know what you’re getting into. Everything else is manageable with a bit of planning.
