Abstract: The invention relates to a surfing installation (10, 10A, 10B) for generating a surfable wave (60), comprising an inclined ramp (50) to the upper end (51) of which water flows via a water inlet (46), which water is accelerated on the ramp (50) to a first flow speed, the lower end (52) of the ramp (50) leading into a region (30) having a lower second flow speed relative to the first flow speed, and a standing wave, in the flow direction, forming in the region (30) as a result of the water flowing at the first, faster flow speed striking the water flowing at the second, lower flow speed.
