Dude! I've lived in Surf City, California (A.K.A. Santa Cruz) for 13 years. For most of that time I was aware that there was a surfing spot a little way up the coast called Mavericks. But until yesterday I had NO IDEA that it was, well. Unbelievable. The wave you see below (if you can call it that, and not a watery armageddon) is not in Hawai'i.
It's off the southern cape of Half Moon Bay, midway between San Francisco and Santa Cruz.
But, get this. It's TWO EFFING MILES (3 effing km) OFF THE EFFING COAST! These monster waves just...happen...in the middle of ['scuse me] effing nowhere!
Apparently there's a unique [no poop!] landform beneath the sea just at that place that concentrates wave power and creates a break point in the middle of the [effing] ocean! And, clearly, it's not just ANY break.
Here's a better image of the bathymetry.
See you at Mavericks!
