Bean Hollow State Beach

Bean Hollow State Beach is a rugged, fairly exposed beach-and-reef break in San Mateo County that is known for being difficult to time: it generally only becomes rideable when wind and swell line up. When it’s working, the left-hand reef section is described as the superior take-off compared with the right, and surfers typically aim for mid tide. Wave conditions are often small or inconsistent, and the break can turn heavy quickly. Sources emphasize short, punchy waves that frequently end in a punishing shorebreak. With larger swell, the spot may become dangerous and disorganized due to heavy closeouts. The cleanest surf conditions are associated with easterly winds, which can be offshore for this setup; prevailing winds that are not offshore can rapidly blow the break out. Because conditions can flip quickly, careful checking of swell period and current/tide timing is a key part of planning a session. Safety is a major factor at Bean Hollow: sources highlight heavy shorebreak, strong rip currents, submerged rocks/reef, cold water, and sharks. On top of that, tide-dependent exposure of hazards means rocks can appear at low tide and become hidden at high tide—so surfers should assume the lineup can be changing even within the same day.
