Dunes Beach is a sandy beach break near Half Moon Bay backed by expansive coastal dunes, offering a more sheltered alternative to the exposed breaks further north. The west-facing beach picks up NW groundswells that wrap into the area, producing mellow waves suitable for intermediate surfers and longboarders. Cold water, fog, and strong currents are standard NorCal conditions, but the relatively calmer surf and scenic dune backdrop make it a pleasant spot.
