World record, 29 Oct 2020
Sebastian Steudtner is the German surfer who holds the world record for the biggest wave ever ridden. On 29 October 2020 he was towed into a wave at Praia do Norte that Guinness World Records later measured at 26.21 metres, or 86 feet. Checking it took a long time: the record was only confirmed in May 2022, about a year and a half after the ride.
He hasn't stopped looking for a bigger one. In February 2024 his own team measured another Nazaré wave at 28.57 metres. That number has never been ratified, so 26.21 metres is still the official mark.

Our formula says: Super giant biggest wave about 25.4 m
Swell from the ERA5 reanalysis (Copernicus / ECMWF) at the hour of the ride. Biggest wave = 1.5 × sets, sets = 2.85 × swell × √(period ÷ 15) on this data scale. How we forecast
One email when giant waves (10 m+) show up in the models, usually 5 to 7 days ahead.
