[1] This has a slight but measurable impact on the spring tide, usually adding no more than a couple of inches.
The Moon and the Sun are aligned every two weeks, which results in spring tides, which are 20% higher than normal.
Spring tides that coincide with the moon's closest approach to Earth ("perigee") have been called perigean spring tides and generally increase the normal tidal range by a couple of inches.
[2] The Ash Wednesday Storm of 1962 coincided with a perigean spring tide.
It inundated the entire Atlantic coastline of the United States, from the Carolinas to Cape Cod, resulting in a loss of 40 lives and over US$500 million of property damage.
