TIL that #Hawaii #waves and #California waves are measured completely differently.
California wave measurement system measures the face of the wave...
Oh btw, we're talking about #surfing.
So if you're standing on shore looking at a wave, and the face is 40'.
That SAME wave by the Hawaii wave measurement system is 20'.
BECAUSE... when people started surfing #Waimea (Hawaii) there weren't spectators on shore, just the surfers out in it, so by necessity they measured the BACK of the wave.
