    The way I do it is to ask a person of a known height to stand at the water edge and sit myelf at a position up the beach where the top of their head touches the horizon. Because of dip this is probably not super accurate but appears to be good enough for pactical purposes. Trying to estimate you height above the water without a reference is more difficult than one would imagine.
