The tidal cycle that is displayed in the Nautical Almanac’s has a cycle rate of roughly 30 days from 1 point to the same point in the next cycle. This means that 1 wavelength of the tidal sinusoidal wave is 2 days longer than the orbital period of the sidereal of the Moon from the perspective of the oceans that rotate with the planet around the common centre of “gravity”.
The Synodic Lunar Month is the cycle relevant to the position of the Sun, its period is 29 days 12 hours. It is clear the Tidal periods mechanism is tied to this period and not the sidereal cycle.
Why is this important?
If we say that the mass of 2 objects rotating around a common centre of “Gravity” and that the orbital period of this cycle is 27 Days and 7 hours then we must also assume the period of the Mass interacting with the ocean on the larger rotating celestial object must follow the same period. Therefore if mass is attracting mass to create the tides as is commonly understood then the period should be the sidereal cycle.
In reality the Moons interaction with the magnetosphere of our Planet follows the Synodic cycle because the magnetosphere only rotates once per year. The change in the Magnetosphere then creates the tidal effects. If we were to use the sidereal cycle the period of the tide would quickly become out of Phase, if mass attracting mass was true we would see the 27.3 day period somewhere in the measured tidal height.
