Beating the Heat in Seoul This August

For roughly a month, Han River parks host outdoor movies, water activities, night markets, and concerts under the Hangang Summer Festival banner. Events are mostly free or low-cost and scattered across Yeouido, Banpo, Ttukseom, and other parks. Evenings are busiest, and riverside lawns can fill quickly in good weather, so arrive early with mats and snacks.

At Daecheon Beach in Boryeong, this festival centers on mud pools, slides, and games using local mineral-rich mud. Many Seoul-based travelers join weekend tours for beach time and concerts. Certain mud zones require paid tickets, while beach access remains free. Nights feature music and fireworks, so staying late or overnight is common.

Revived in 2026, this festival highlights Itaewon’s international character through street food, parades, and performances. The main road becomes pedestrian-only, hosting stalls and evening parties. It can be extremely crowded at night, particularly around bars and clubs. Families may prefer daytime hours before nightlife intensifies.

Seoul POPCON at COEX gathers comic, anime, game, and film fans for panels, merchandise booths, and celebrity signings. Cosplay is common, and families as well as hardcore fans attend. One-day tickets are moderately priced, but certain autograph sessions add extra fees. Crowds form early at popular booths, so arrive near opening if you want shorter lines.

If confirmed, the Seoul ePrix will bring electric car racing back to a street circuit around Jamsil Olympic Stadium. Grandstands, fan zones, and technology exhibits showcase EV innovation alongside racing. Road closures in southeastern Seoul will be significant during event days. Tickets are required for grandstand access, while nearby residents will mainly experience noise and traffic changes.

On August 15, official events at the Sejong Center and elsewhere commemorate Korea’s liberation from Japanese rule. The public may see flag displays, concerts, and exhibitions at Gwanghwamun Square. Many museums offer free admission that day. Some offices and banks close, but most tourist-oriented businesses stay open.

SIDance presents contemporary dance companies from Korea and abroad at Seoul Arts Center and other theaters from late August into September. The program includes modern ballet, experimental works, and an outdoor preview, often at Dongdaemun Design Plaza. Tickets are show-specific and moderately priced. It is ideal for dance enthusiasts seeking international perspectives.
