SEOUL, Aug. 6 (AJP) — South Koreans have joined Europeans and Americans in sweating through one of the world's hottest summers. But to borrow an old saying, if you can't beat the heat, join it.

Across Seoul, children have declared war on the thermometer. Instead of hiding indoors as temperatures flirted with 40 degrees, they cannonballed into pools, sprinted through fountains and chased water jets across the city. Under a relentless sun, the season that often feels unbearable became something to celebrate.

At Gwanghwamun Square, where office workers usually weave through crowds beneath the watchful gaze of King Sejong, summer arrived carrying buckets of water instead of briefcases.

The 2026 Seoul Summer Beach transformed the heart of the capital into an oversized playground complete with an eight-meter water slide, swimming pools, fountains and a stretch of imported sand.

Children raced barefoot between splashes, leaving wet footprints across stone plazas better known for protests and parades. Office towers shimmered in the heat while squeals of laughter briefly drowned out traffic.

For a few hours, downtown Seoul traded its suits for swimsuits.

Further east, at Gwangnaru Hangang Park, the city's famous river did what it has done for generations — offered Seoul a place to breathe.

Children darted through shallow pools beneath wide blue skies while parents stretched out in the riverside breeze. Cyclists rolled past, joggers slowed to watch, and water drifted through the air with every gust of wind.

Unlike Gwanghwamun's urban beach, Gwangnaru lets the river become part of the scenery. The skyline still towers in the distance, but the water makes the city feel miles away.

In northern Seoul, Hwarangdae Railway Park swapped trains for torrents.

The former rail yard now echoes with children racing down a 50-meter inflatable slide, floating along a lazy river and scrambling through climbing pools. Each splash at the bottom was followed by the same routine: a sprint back to the top for another turn.

Tracks that once carried passengers now carry the soundtrack of summer vacation.

Not every summer memory needs a tropical island or an expensive resort.

Sometimes it is a temporary pool in a city square. Sometimes it is a fountain beside a river. Sometimes it is an inflatable slide built where trains once ran.

The pop-up playgrounds remain open through August, with the Seoul Summer Beach at Gwanghwamun operating through Aug. 9, the Honey Jam Water Park at Hwarangdae Railway Park through Aug. 16, and the Gwangnaru Hangang Park water playground through Aug. 30.

As another sweltering day settles over Seoul, the city keeps finding new ways to cool itself.

Water rises between skyscrapers, drifts across the Han River and splashes through old railway tracks.

For a few precious hours, the hottest city in the country becomes its biggest water park.
