This is not specific to Mavericks amongst “big wave” surf spots. Waves break as a function of swell period vs. ocean depth. More powerful (longer period) swell will break in deeper water, so in many places known for big waves, shorter period swell will just go right over and not break until closer to shore.

That's why a lot of breaks are literally un-surfable in bigger swells. What was once a nice sandbar or reef, now only has whitewater and their are waves breaking well past the usual spot--usually in a way that is either two dangerous or not fun.

I remember paddling out at C-Street in Ventura in 14-17ft swell...didn't surf a thing and thought I was going to die. Go on a 4ft day and you will be lucky to find a place in the line-up.

Most people are going to think they're going to die in triple overhead surf at any break

Of course. Mavericks needs the swell but the location provides the geographic feature, a ramp which builds and slows the swell.

Without the exceptional swell conditions there is literally no wave, just a swell. Monster rogue waves will break offshore regardless of depth.
