Is this the biggest wave ever surfed? Tom Butler, a 29-year-old British surfer from Cornwall may have ridden his way into the record books after taking on an enormous wave estimated to be more than 100ft high (about 30 meters) at Nazaré in Portugal on Dec. 14. /VCG Photo

Butler is confident that his potential record breaker has beaten the previous record of 80ft (about 24 meters) set earlier this year by Brazilian surfer Rodrigo Koxa, claiming it's the biggest wave surfed in the world this season, according to Daily Mirror. /VCG Photo

"It was a monster. I know that for sure. It's like running from a raging bull; you don't stop to think about how much it weighs - if you get eye contact, then you've already failed," the surfer said to the UK newspaper. /VCG Photo

Butler must now submit photographic evidence of his deeds to the World Surf League, which will judge the claim ahead of an awards ceremony in April. /VCG Photo
