In a slice of the Atlantic Ocean he says is "known as a place of death, not of riding waves" according to the Time.com, pro surfer Garrett McNamara may have broken his own world record.

Monday, January 28, in the waters off Nazare, Portugal, the Hawaiian surfer McNamara wrangled what multiple sources are reporting as a 100-foot wave.

Once the wave height is verified, he will have broken his own world record. McNamara surfed a 78-foot wave at the very same rocky coastline in 2011.

Apparently there's an underwater canyon off Nazare which has the capacity to generate monster waves, according to the BBC.

A crowd of people watched the 45-year-old tame the massive wave. You can check out his incredible ride in the slideshow above and the video below.
