Just curious,When you guys go out and tell your boys,hey it was 4 foot today or give a surf report, how are you measuring your wave?Are you looking at it from the front or the backside of the wave?Myself I look at it from the front even thou thats probably the wrong way.I mean I think theirs a pretty big difference .It seems like a 8 foot wave can only be a 5 footer.Just wondering what swellifo and the rest of the sites do.Anybody know???
