Considered one of the places on earth with the biggest waves in the world, this is my home land, and I'm proud of it, the video is a little bit old, I will try to post future videos soon.
Wikipedia: "The Nazaré Canyon is an undersea canyon just off the coast of Nazaré, Portugal, in the Eastern Atlantic Ocean. It has a maximum depth of at least 5,000 metres (16,000 ft) and is about 230 kilometres (140 mi) long.[1]
The canyon is being studied as part of the EU HERMES project using a remotely operated vehicle. The project is investigating the specialised canyon ecosystems, sediment transport and deposition, and the way in which the canyon influences and is affected by local ocean circulation.[2]
The Nazare Canyon causes very high breaking waves.[3] 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 Praia do Norte, Nazaré, Portugal.[4] 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.[5]
Hugo Vau could have smashed a world record amid claims he surfed one of the biggest waves ever seen at Nazare, 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.[6][7]"
