The Nazaré Canyon is an undersea canyon just off the coast of Nazaré in Oeste region of Portugal, in the Eastern North Atlantic Ocean. It is the largest submarine canyon in Europe, reaching depths of about 5,000 metres (16,000 ft) deep and a length of about 230 kilometres (140 mi).The Nazaré Canyon off the coast of Portugal.
Praia do Norte, Nazaré (North Beach) was listed on the Guinness World Records for the biggest waves ever surfed (formed under the influence of the Nazaré Canyon).The canyon is being studied as part of the EU HERMES project using a remotely operated vehicle. The project is investigating the specialized canyon ecosystems, sediment transport and deposition, and the way in which the canyon influences and is affected by local ocean circulation.
One of the most distinct features of this canyon is the high breaking waves it forms. This makes Nazaré, specifically Praia do Norte, a hotspot for big wave surfing.In November 2011, Hawaiian surfer Garrett McNamara surfed a record breaking giant wave: 24 metres (79 ft) from trough to crest, at Praia do Norte, Nazaré, Portugal. In January 2013, it was reported he successfully rode a wave measuring an estimated 30 metres (98 ft) at the same location, possibly exceeding the size of his previous record-breaking wave.In January 2018, Hugo Vau might have smashed a world record amid claims he surfed one of the biggest waves ever seen at Nazaré, Portugal. The wave — nicknamed ‘Big Mama’ — was reported to be up to 35 metres high, which, if confirmed, would beat current Guinness Book of Records holder Garrett McNamara.Brazilian surfer Rodrigo Koxa has officially broken the world record for the worlds biggest wave ever to have been surfed, with his incredible run at Nazare beach in Portugal being recognized as a Guinness World Record. In May 2018, the World Surf League confirmed this achievement at its Big Wave Awards in Santa Monica, California, with the official height of the wave registered at 24.38 m (80.0 ft).On February 11, 2020, at Praia do Norte in Nazaré, Portugal, Maya Gabeira broke the record for the biggest wave ever surfed by a woman on a record-setting wave measuring 73.5 feet (22.4 meters), besting her own previous world record of 68 feet. The 73.5-foot wave she surfed on February 11 in Nazaré was the largest wave surfed by anyone that year, earning Gabeira the WSL’s 2020 women’s XXL Biggest Wave Award. By contrast, that year’s men’s XXL Biggest Wave Award winner, Kai Lenny, rode a 70-foot wave.
