Mavericks, Winter surf spot in Half Moon Bay, United States.

Mavericks is a surf spot off the coast of Half Moon Bay in the United States, known for waves that reach up to 60 feet (18 meters) during winter storms. The formation occurs over an underwater rock structure that pushes water upward and creates steep walls.

In early March 1967, Alex Matienzo, Jim Thompson and Dick Notmeyer surfed the waves off Pillar Point, accompanied by Matienzo's roommate's white-haired German Shepherd, Maverick, who swam out to them; the break was named after the dog. In 1975 Jeff Clark, aged 17, paddled out alone and became the first documented person to ride Mavericks head-on.

The spot takes its name from a white dog named Maverick who followed his owner out to surf here. The name became shorthand among California surfers for waves that demand courage and skill.

Access is made by paddling roughly half a mile from Pillar Point Beach, and winter conditions between November and March bring the largest waves. Cold water, currents and rocks require experience with big waves and proper equipment.

The seafloor relief consists of a sloping ramp with deep troughs on both sides, allowing water to break in both directions at the same time. This double-sided mechanic makes each wave a rapidly changing scenario.
