Pedro Scooby -- one of the best big wave surfers in the world -- caught a MASSIVE wave in Portugal on Monday ... and his insane ride was all caught on video!!
Scooby dropped in on the wave during the TUDOR Nazaré Tow Surfing Challenge ... and check out the footage, the ocean swell was seriously monstrous.
Unclear exactly how high the peak of the wave ultimately was -- it appeared to be somewhere in the 60-foot range -- but Scooby bombed it nonetheless.
