Surfer rides what could be a record breaking 100ft wave

A thrill-seeker could have broken his own world record for the largest wave ever surfed when he caught one that reportedly measured 100ft.

Garrett McNamara, who was born in Massachusetts, US, but moved to Hawaii aged 11, surfed the giant wave off the coast of Nazare, Portugal, yesterday.

The surfer could be set to break his own world record that stands at 78ft, which he also rode in Nazare at the end of 2011.

McNamara said the world record wave (below) was: "The most challenging, dangerous wave I’ve ever surfed – it’s the only place in the world in which a giant canyon reaches all the way to the beach.”

McNamara's 78ft ride beat the previous world record, held by Mark Parsons, by one foot.
