For instance, try comparing Virginia Beach, VA and Solomon's Island, MD
. Moonrise/set times are within a couple of minutes of each other, but
the tides are six hours out of synch.

Why? Well, obviously it takes some time for the large bulge of water
that is the tide to make its way up the Chesapeake Bay. Since water
doesn't move instantly, moonrise is essentially useless for predicting
tides on large bays.

I ask Uncle NOAA for tide info.
