Surf: World famous tidal bore that pushes up the River Severn on spring high tides. Can be ridden for miles - around 6 is the record. Has many moods and shapes depending on river flow, tide height, following winds etc. Nice and open walls of whitewash and various shoulders at the wider parts of the river around Newnham down to tight peelers close to the bank from the Severn Bore Inn onwards. Finishes at the weir (and can rebound off it with a rideable wave back down the river) after the last section at Over. Popular with longboarders, kayakers and waveskis. Best caught between Fretherne and Maisemore and it's very easy to catch the same wave multiple times by driving between easy access spots. Can be overhead one minute, then suck back into the bank and drop everyone off as it hits deeper water. Environment: Watch out for submerged objects like tree stumps that make the wave explode, sending riders into the trees along the bank. Barbed wire, dead sheep, bridges and the slippery banks are all hazards and the surge behind the wave is especially strong - plan your exit strategy and don't surf alone or at night.
