Dylan Graves hails from Puerto Rico and, as of late, has taken on a career as a strange wave surfer. His “Weird Waves” series of videos is just that, Graves chasing novelty waves around the world. This episode, in England, sees Graves hot on the trails of the Severn River Bore, a literal tidal wave created by massive tide swings at the mouth of the Severn. When the tide is right, waves pulse through the river, and a small community of surfers rushes to great them. They rush by car from breaking section to breaking section, slipping down muddy riverbanks on their butts, desperate to beat the wave to the next mud bank. It’s madcap and beautiful.
