A blue ocean washout is a tropical wave that forms when water from a tropical rainforest or oceanic mountain pool drains onto the ocean.
These waves form in a large pool and can reach as high as a mile above the surface of the water.
The waves often travel for several hours before breaking.
The blue ocean waves are created when the water evaporates from the sea floor into the ocean, creating the blue water in the pool.
The pool can also be found on the ocean floor or even in a storm drain.
