Tides are shallow water waves, a shallow-water wave  speed is controlled by depth of ocean
Tide waves are forced waves at most latitudes because the tide-generating forces move faster than the speed of a shallow water wave of the tide wave wavelength. The tide lag is at a maximum at the equator and is reduced at higher latitudes.Chapter 10 tides
