Biggest Waves Ever Surfed - Nazaré. April 8, 2016. The waves at Praia do Norte, Nazaré, are famed for being among the largest in the world. On November 2011, surfer Garrett McNamara surfed a record-breaking giant wave: 78 feet (23.8 m). On 28 January 2013, McNamara returned to the spot and successfully surfed a wave that appeared even larger (waiting an official measurement).
