The video shows a surfer riding a massive wave in the ocean. The wave is so large that it creates a tunnel-like effect as the surfer goes through it. The surfer is wearing a wetsuit and is seen skillfully maneuvering the surfboard on the wave. The ocean is a deep blue color, and the wave is a lighter shade of blue with white foam at the top. The sky is overcast, and there are no other surfers or objects in the water.
