So, let's go surfing. That anyway was the plan for Garrett McNamara, from Hawaii

This isn't Hawaii, however.

This estimated 90-foot wave was off a beach in Nazare, Portugal.

McNamara says he believes it's the biggest wave ever surfed.

One minute you're surfing along, and the next, there's nine stories of water next to you...

The coast of Nazare is home to one of the only deep water canyons --up to three miles down-- that runs all the way to shore.

McNamara says the the underwater canyon receives swells from the Atlantic Ocean and creates unusually large waves.

The record wave's 90-foot height still must be verified through videos and photos to officially eclipse the old "big wave" surfing record of 77 feet.
