New York City’s got plenty of rivers nearby, but aside from giving Trump more coastal real estate to take over, they don’t really do anything. No massive waves that we could use to surf to work, anyhow. If only we lived near Bristol Channel in England, where a high-tide phenomenon called a tidal bore could be letting us river surf at nearly this very moment.

A tidal bore occurs when a large incoming tide flows in such a way as to form a wave that pushes itself along a river. They’re pretty rare, happening only when uncharacteristically high tidal waters are quickly funneled into an especially narrow estuary. One of the world’s most famous, England’s Severn Bore, sent its first major wave of the year up the River Severn yesterday, carting along with it surfers from around the world. The wave was dinkier than usual thanks to lousy winds, but with favorable conditions it can be quite powerful. Last year, for instance, it carried a railroad engineer from Gloucestershire for 7.6 miles, earning him the world record for longest surf—and, we assume, awesome street cred throughout Gloucestershire.—Abby Seiff
