Shark Pit 1 (Dillon Beach)

Shark Pit 1 (Dillon Beach) is an exposed, sand-bottom beach break where surfers look for reasonably consistent groundswells and the right wind window. The spot is strongly associated with east to east-southeast offshore winds that can clean up the face, while conditions can worsen when other wind directions bring chop and turbulence. Surf quality is tied to swell: west swell is commonly described as the best direction, and winter swells are when the break can become very powerful. On larger days the southern end can deliver heavy, fast sections that often transition into closeout behavior, and the wave energy is frequently paired with hazardous coastal dynamics. Safety is the central concern. The spot is known for sharks and rocks, and the water is consistently cold. Strong tidal currents and rip currents are reported near the Tomales Bay mouth, with outgoing tides described as particularly risky when currents pull toward the channel. Access and comfort are limited compared with more developed areas. While there are local amenities (including parking and toilets), the environment remains remote and self-reliance is important; plan for cold-water protection and reduced on-the-day safety support. Overall, it is best approached as a challenging, high-hazard surfing location rather than a casual spot.
