  description: Manasquan Inlet is the gold standard of New Jersey surfing—an inlet-enhanced beach break that produces the Garden State's most consistent and powerful waves. The inlet jetty creates sandbars that transform ordinary Atlantic swells into legitimate overhead peaks, with fast, hollow sections that reward aggressive surfing. The local crew is notoriously protective and skilled, having earned their waves through decades of cold water dedication. When hurricane swells or nor'easters hit the Jersey Shore, Manasquan is where serious East Coast surfers want to be.
