Monday night’s full supermoon had plenty of pull with yesterday’s high tide. That tide was a 12 ½ -footer, our highest predicted tide for March, according to Center Harbor data. We also had fog coming in with the tide yesterday, making the effect more dramatic.
As you can see above, the tide reached high onto the banks of Great Cove. On the other side of our peninsula, it climbed the Town Dock to about two feet from the top:
Tides actually are very long waves that are pulled back and forth and made to bulge by the gravitational effects of the moon and sun on the Earth. When the sun, Earth, and moon are in alignment, the moon not only appears “full” (of light), the pull of the sun on the tides is added to the pull of the moon. This makes the oceans bulge deeper than at other times. (Brooklin, Maine)
