Poloboya, a sport invented in Barcelona, draws players from around the world to Sant Sebastià Beach. The only rule: float and have fun. With no scorekeeping and a welcoming spirit, the game has become a summer tradition.
Each summer, Sant Sebastià Beach in Barcelona hosts a game that looks nothing like the usual seaside sports. Poloboya, created in 2017, turns a buoy into the center of a loose, joyful contest. From the shore, it’s easy to miss. But swim out 170 meters and you’ll find a group in water polo caps, weaving through the water, passing a ball, and aiming to hit the buoy—after at least three passes.
There’s no scoreboard. If you tap the buoy with your head, it counts double, but nobody’s really keeping track. The main idea is simple: if you can float, you can play. The group’s motto, “Si flotes, vine, que riurem,” sums it up. Players come from nine countries, and anyone is welcome, regardless of age or background. Even some Atlètic-Barceloneta water polo pros have joined in, but the mood stays relaxed and open to all.
Sant Sebastià Beach is officially classified as a bathing site by the EU, with an 'Excellent' water quality rating for the 2025 season.
Poloboya started out of frustration. Manel, tired of waiting for the ball during a water polo class at Club Natació Atlètic-Barceloneta, began practicing alone with a buoy. Soon, others—David, Joana, Carlos—joined him, and what began as a solo routine became a group event. One day, a stray ball drifted over to a group of Californian water polo players in town for a youth championship. They joined in, raising the level of play, but the spirit stayed the same: skill is optional, enthusiasm is not.
Games are set up through a chat group with over a hundred members. If at least six people say yes, the game is on. Teams can be as small as three or as big as six per side, and sometimes the group splits into three teams to keep everyone playing. Matches have happened at dawn, under a full moon, and even in secret, with only the group’s Instagram, @poloboiala, showing proof of these late-night games.
This year, on September 20, the 10th Poloboia World Championship will take place at the same beach. The event is sponsored by El vaso de oro, a local bar that has supported the group from the start. The championship is more about gathering the community than winning a title, and it’s become a neighborhood tradition in Barceloneta. The event is expected to draw even more attention to a sport that values spontaneity and inclusion over competition.
According to independent sources, current water conditions at Sant Sebastià Beach are highly favorable for aquatic activities, with a temperature of 27°C, minimal wave height around 0.1 meters, and light winds. The area is also characterized by very low tidal amplitude and gentle water dynamics throughout the day, making it particularly suitable for open water games.
While the city’s schools start the academic year with their own challenges, the mood at Sant Sebastià Beach is all about sharing the water and enjoying the moment. Poloboya has grown from a small experiment into a fixture of Barcelona’s summer, without losing its easygoing spirit. With no strict rules and a focus on fun, the game brings together a mix of locals and visitors, showing that sometimes the best ideas are the simplest ones—just float, play, and laugh together.
