The wave is measured not by the suck out section just as it stands up but by the size of the rippable wall out front. Even a knee high wave will stand up and be chest high when it first hits the sand bar. The problem is 10 feet down the line it is knee high again. The waves yesterday would jack up to be probably 6 feet high right as they broke but the majority of the ridable and rippable part of the wave was still only waist high at best. I dropped in on a wave and got barrelled without ducking more than my head. After that cover up the wave was waist high at best not 20 feet down the line from the barrel. That's why we call it waist high. You say east coast waves suck and are mostly under head high but you said yesterday was head high?
