Why are the tides not the same every day?

Tides are not the same every day due to the gravitational influence of the moon and the sun, which varies in position relative to the Earth. The elliptical orbit of the moon, along with the sun's changing position throughout the year, causes fluctuations in tidal heights and timings. Additionally, local geographic features and weather conditions can further affect tidal patterns. As a result, tides follow a complex cycle that leads to variations in their daily occurrence.
