A man is surfing a stationary wave in a river in Rotterdam, Netherlands. He is wearing a red long-sleeved shirt and black shorts, and is on a white surfboard. The river has green-brown water and is bordered by a concrete embankment on one side and a paved walkway on the other. Buildings, trees, and people are visible in the background on the far side of the river. The sky is overcast, suggesting it is daytime, possibly late morning or early afternoon. The man appears focused and determined as he maneuvers on the wave. Text visible on the embankment reads "STAFF ONLY" in red spray paint.
