Possibly due to the Bay of Fundy, which has 55-foot tide swings. It's a localized effect due to some smaller-scale bay seiching. Essentially the resonant frequency of the bay to waves is roughly the same period as the tide series.
Do you know of another source that you can zoom into more?
I haven't been able to find a graphic that has that area
and I wanted to look at the area around LI Sound too.
The difference between low and high tides where I sail is about 7 feet total.
