When’s the Best Time to Visit Korea?
Generally, Spring (March to May) and Autumn (September to November) are considered the best times to visit South Korea. The weather is mild and pleasant, which makes it ideal for outdoor activities, and each season puts on a show: cherry blossoms in spring, colourful foliage in autumn.

In February, the Taebaeksan Mountain Snow Festival in Taebaek is a must-visit, showcasing hundreds of ice statues carved by sculptors from around the globe.

September in Korea

September brings the start of autumn, with the perfect weather for vibrant traditional festivities. The big one is Chuseok, Korea’s Thanksgiving, which falls on 24 to 26 September in 2026. Families gather to honour ancestors, share traditional foods, and enjoy festive activities.
As one of the biggest holidays in Korea, many people travel to their hometowns, so expect roads and transport to be packed in the days leading up to it. Lots of places close, so check operating hours in advance.
The upside: as locals travel out, you’ll find shorter queues at popular tourist spots, and you can even snag discounts on Everland tickets.

Don’t worry, you can still experience authentic Chuseok spirit at popular historic sites. The royal palaces and museums in Seoul line up plenty of traditional and cultural events. We recommend the Korean Folk Village and Namsangol Hanok Village, which also serve traditional dishes like songpyeon (rice cakes symbolising a good harvest) and galbijjim (braised short ribs).

You can also check out the Taean Autumn Flower Expo at Korea Flower Park in Taean, Chungcheongnam-do. Set by Kkotji Beach on the western coast, it showcases chrysanthemums, verbenas, angelonias, sunflowers, and globe amaranths along scenic floral pathways, making it a lovely couple or family outing.
Activities and festivals to catch in Korea during September:

FAQs About Visiting Korea (2026)
April and October are the two best months. April brings cherry blossoms and mild spring days, while October delivers crisp air, clear skies, and the start of autumn foliage. Both skip the summer rain and the winter freeze, which makes them the most comfortable times to travel and sightsee.
January and February are the cheapest, as long as you skip the Seollal week (16 to 18 February in 2026). Cold weather means low demand, so flights and hotels drop to their lowest of the year. Early March and late November are good value too, with near-peak scenery at off-peak prices.
Avoid mid-July to August if you dislike heat and rain, since that’s the monsoon and typhoon stretch. The Seollal and Chuseok holidays also see many shops and restaurants close, though the city itself goes quiet and peaceful as locals head home. If you visit during either holiday, book your transport weeks ahead.
Late March to mid-April. The blooms start in the south (Jeju and Busan flower first), then sweep north to Seoul. For 2026, Seoul’s blossoms are forecast to peak around 7 to 12 April. Each spot stays in full bloom for only about a week, so timing matters.
This one’s a bit of a red herring for travellers. The “3-day rule” is a Korean dating and K-drama trope about waiting three days before texting a love interest, not a rule about visiting the country. For trip planning, the timing that actually matters is blossom season, foliage season, and the holiday closures.
Five to seven days is the sweet spot for a first trip, enough for Seoul plus a side trip to Busan or Jeju. With 10 days you can comfortably cover all three. A long weekend works if you’re sticking to Seoul alone.
