This media file captures a moment of surfing on a river wave in Rotterdam, Netherlands. The primary subject is a person on a surfboard, wearing a red shirt and dark shorts, actively riding a powerful wave. The surfer's body is positioned for balance and control, with arms extended to manage the ride. The water is a greenish hue, indicating it is likely a river or canal, and it's churning with white foam from the wave. The scene is set alongside a paved walkway bordering the river. A concrete barrier runs along the edge of the walkway, and on this barrier, red spray paint spells out "START ONLY!". This suggests a designated area or a warning related to the surfing activity. In the background, a concrete wall forms the far bank of the river. The lighting suggests it is daytime, likely sunny due to the clear visibility and shadows. The overall atmosphere appears to be one of dynamic action and urban water sports. Another person's legs are visible in the water at the bottom of the frame, possibly waiting to surf or observing the activity.
