The 33-year-old rode a 73.5-foot wave in Praia do Norte, Portugal, on February 11, beating her previous record by 5.5 feet. She made history in 2018 after surfing a 68-foot-high wave in the same waters.
Since measuring the size of waves is difficult, teams from the University of Southern California, WaveCo Science Team and Scripps Institution of Oceanography reviewed videos of the surfer’s feat to confirm she once again broke the record, according to Guinness World Records.
The teams used scientific calculations based on real-world coordinates as well as Gabeira’s height and the length of her board to determine the measurements, the organization said.
Gabeira, who began surfing when she was 17, was knocked unconscious in 2013 while in the water and was rescued by a fellow surfer — but it didn’t stop her from getting right back on her board.
