Why are we able to predict tides?

Tides can be predicted due to the gravitational interactions between the Earth, the Moon, and the Sun. The Moon's gravitational pull creates bulges in the Earth's oceans, resulting in high tides, while areas between these bulges experience low tides. These patterns follow a regular cycle influenced by the relative positions of the Moon and Sun, allowing for accurate predictions based on established astronomical models. Additionally, historical tide data enhances the precision of these predictions.
