Trifecta's surf arena in Singapore runs on CityWave's Deep-Water technology, producing an adjustable standing wave about ten meters wide and up to a meter and a half tall. Multiple riders can be on it at once at different settings, so beginners can hold a grab rail while stronger surfers work the open water for turns and airs. It's part of a bigger Orchard Road complex that opened in 2023 alongside an indoor snow slope and a skate bowl, so you can hit three board sports in one afternoon. Sessions aren't cheap, running close to SGD 100, but for a city with no rivers or ocean swell, it's the real deal.
