Surfer rides potential world record wave at Mavericks in California

On Christmas Eve, surfer Alo Slebir rode a wave at Mavericks that witnesses estimate was over 100 feet tall, potentially setting a new world record. This wave, if confirmed, would return the record to California after being held by Portugal since 2022. Measuring the height of waves is complex and relies on a process called photogrammetry, which involves comparing the size of the surfer to the wave. Experts will review photos and videos to determine the wave's height, but this process can be subjective and contentious. The current world record is 86 feet, set in Portugal. The next meeting to confirm any new records will take place in September 2025, where experts will evaluate Slebir's ride and other submissions.
