A substantially pyramid-shaped wave diverter (1) having circular-shaped ports (6). A system of wave diverters (14) may be placed in an ocean (16) side-by-side off a shoreline (17) and under the surface of water. The system of multiple wave diverters each have circular ports (6) located on each side, some of which may vary in size. The system of wave diverters divert the flow of sand toward the beach (18) and prevents further erosion from the beach.
