A "Cliffwood Beach" directional sign is seen briefly in the 1939 documentary The City (with music by Aaron Copland). An unending traffic jam getting to the beach is used in the film as an endemic problem of unplanned growth.
Cliffwood Beach was a popular resort until the 1960s, with a boardwalk, saltwater swimming pool, dining and dancing at The Cat 'n Fiddle, and other amusements. The beachfront facilities were destroyed by Hurricane Donna in September 1960. All that remains is the swimming pool, though it is currently buried in a sand dune that helps support part of the sea wall.
Cliffwood Beach was an early recipient of aid through the New Jersey Department of Environmental Protection's Green Acres Program , which was established in 1961. The township received funds to build a park near the Cliffwood Beach waterfront.
