Watch above as Jamie O'Brien and his buddies built and surf an epic standing wave at Waimea River. Watch it gets bigger and bigger as the party goes on!
"Every winter on the North Shore of Oahu the high surf dams the Waimea river-mouth with sand, and the heavy rains flood the valley. During a flatspell, locals led by Jamie O’Brien happily dig out the channels to create a standing wave to get their feet in the wax in preparation for Pipemasters."

Wanna know more about the wave? Wikipedia says, "The Waimea River is a river on the island of Kauai in the U.S. state of Hawaii. At 12.1 miles (19.5 km) in length,[1] it is one of the longest rivers in theHawaiian Islands.
It rises in a wet plateau of the island's central highlands, in the Alaka'i Swamp, the largest high-elevation swamp in the world. It flows south, passing through the spectactular 3,000-foot-deep (910 m) Waimea Canyon, known as the "Grand Canyon of the Pacific."
The valleys of the Waimea River and its tributary, the Makaweli River, were once heavily populated. It enters the Pacific Ocean at Waimea, near the 1778 landing place of Captain Cook on Kauai."
