Pro surfer Makua Rothman successfully rode a wave that was estimated to be about 100 feet tall over the weekend ... and the insane ride -- which some believe is a world record -- was all caught on video!!
The drop-in went down in Hawaii on Saturday ... when Rothman and some of the rest of the country's best big wave surfers hit up a famous area known as "Jaws" in Pe'ahi to tackle some gnarly swells.
At some point during the day, though, Rothman beat out the other surfers to catch a Holy Grail type of ocean ride -- tackling a wave that was estimated to be between 80 and 100 feet high!!
Surf industry officials close to Rothman tell TMZ Sports the wave might very well be the tallest ever surfed -- beating Rothman's previous record of around 66 feet.
After he finished the epic ride, Rothman was PUMPED over it all ... telling us, "I'm so stoked on this ride and everyone who made that day possible!"
FYI, for as good as Rothman is ... he ain't a stranger to falling on these types of waves -- remember back in 2018 when he got thrashed by a huge one??
Yeah ... definitely don't try this at home, kids!!
