As the world turns, high tides arrive later
FROM TODAY'S PRINT EDITIONS:
Terri Clayman, in Columbia, noticed that the high tide on the Outer Banks was roughly 50 minutes later each day. “We were surprised that there was such a difference in the times. What is the reason?”
The moon’s gravitational pull creates the high tides - twin bulges in the ocean, one on each side of our spinning planet.
The moon moves east a bit each day as it orbits the Earth, so it takes about 50 minutes longer, as Earth spins, for your beach to catch up to that same tidal bulge.
