Mavericks

Half Moon Bay, USA (CA)
⚠️Shallow🪨Rocks🪸Sharp reef

Mavericks is Northern California's big wave proving ground—a cold, shark-infested, boulder-strewn reef off Half Moon Bay that produces some of North America's most dangerous surf. The wave breaks over a submerged rock field, creating an unpredictable playing surface that has claimed lives. When winter storms send massive NW swells down the coast, Mavericks holds waves in the 40-60 foot range. The competition here has become one of big wave surfing's most prestigious events. Paddle-in purists still consider it the ultimate test.
