The video shows a man in a black wetsuit surfing on a large wave in the ocean. The wave is so big that it creates a tunnel-like effect around the surfer. The man is seen paddling on his surfboard, standing up, and riding the wave. The water is a deep blue color, and the wave is a lighter shade of blue with white foam on top. The surfer is the only person visible in the video, and he appears to be skilled at maneuvering on the wave.
