The Moon does not lift the water under itself on cue. Every port has its own lag — hours, sometimes most of a day — between the Moon crossing the meridian and the tide coming in.

The ocean is shallow, full of continents, and has its own preferred rhythms, so the tide is less a bulge following the Moon than a wave sloshing round ocean basins with the Moon as the metronome. Sailors call the local lag the establishment of the port, and it was tabulated for centuries before anyone could explain it.
