Under the traveling sun and moon, the earth surface moves to lower altitudes in various rates and various times whose peak is at the begining and the middle of lunar dates.
Seawaves ain’t caused by the strong wind. The tides ain’t caused by celestial bodies’ gravity. The coffees, pools, lakes etc. never becomes different i.e. undergoing up and down, either in tides condition or no tides.
The reality is: the earth breathes:
Its surface goes up and down all the time, in big scales or small ones.
