June in Seoul divides neatly into two halves. The first half of the month features warm, comfortable weather and among the lowest tourist numbers of the warm season, making it one of Seoul’s best-kept travel windows.
The second half brings the start of jangma (the Korean rainy season), with intermittent heavy rain that requires a flexible approach to itinerary planning but does not stop Seoul from being a very rewarding destination.
Quick Answer: Seoul in June: Early June: warm and dry (highs of 24 to 27 degrees), excellent conditions, low crowds. Late June: jangma rainy season arrives with frequent heavy showers and rising humidity (highs of 27 to 30 degrees). Fewer tourists than May or October. A compact waterproof jacket is essential from mid-June. See the Korea in June for the national Korea June picture.
Seoul Weather in June
Early June (1 to 14)

Mid-June (15 to 22)
Highs of 25 to 29 degrees. Lows of 18 to 21 degrees. Jangma begins to arrive. Humidity rises—intermittent heavy rain interspersed with clear periods. A waterproof jacket becomes necessary.
Late June (23 to 30)
Highs of 27 to 31 degrees. Lows of 21 to 24 degrees. Full rainy season. Warm and humid. Frequent showers. The heat makes outdoor sightseeing comfortable. Early morning and evening are the most comfortable outdoor windows.
What to Do in Seoul in June
Early June: Outdoor Seoul
The first two weeks of June are excellent for outdoor activities in Seoul. The palace grounds (Gyeongbokgung Palace guide, Changdeokgung Palace guide) are fully green after spring. The Han River parks (Yeouido Hangang Park guide, Banpo Hangang Park guide) are busy with evening picnic culture as temperatures warm. Bukhansan (Seoul’s national mountain park; see the Korea hiking guide) is accessible and atmospheric in early-summer greenery.
Night Markets and Night Life
June is the beginning of Seoul’s outdoor night market and street food season. The Hongdae guide area evening street culture (street performers, outdoor bars, music) is at its most active from June onward. See the Seoul nightlife guide.
Rainy Season Alternatives
When jangma rain arrives in late June, Seoul’s indoor culture becomes the itinerary. The National Museum of Korea, Insadong guide, covered alleys, Gwangjang Market guide, Market’s covered food hall, and department store shopping are all good rainy-day options. jjimjilbang (see the jjimjilbang guide) is also a good option.
Food in Seoul in June
June introduces summer food culture: cold naengmyeon noodles appear on more restaurant menus, bingsu (shaved ice dessert) stalls open, and outdoor pojangmacha (orange tent stalls) with spicy street food operate into the warm evenings. See the Seoul food guide.
June Events in Seoul
- Memorial Day (June 6): National holiday. Seoul city center is quieter than usu—specialal ceremonies at the National Cemetery and the War Memorial.
- Queer Culture Festival (June): Seoul Pride is typically held in late June at Seoul Plaza, one of the largest LGBTQ+ events in Asia.

Crowds in Seoul in June
June has the lowest international tourist numbers of any warm-weather month. Early June, in particular, offers good access to major sites without peak crowds. The trade-off is jangma in the second half, but the combination of comfortable early June weather and lower prices makes it one of the better months for those who cannot travel in May or October.
