"The Nazaré Canyon is an undersea canyon just off the coast of Nazaré, Portugal. The Nazare Canyon causes very high breaking waves. This makes Nazare a hotspot for big wave surfing. In November 2011, Hawaiian surfer Garrett McNamara surfed a record breaking giant wave: 78 feet (24 m) from trough to crest, at Nazaré. In January 2013 it was reported that he successfully rode a wave measuring a maximum estimate of 100 feet (30 m) at the same location and possibly exceeding the size of his previous record-breaking wave."
