How does the occurrence of a full moon affect the height of tides?

Well, sweetheart, when there's a full moon, it causes gravitational forces that pull at the oceans, making the tides higher than usual. It's like the moon is flexing its muscles and showing off its tidal-pulling powers. So if you see a full moon, better watch out for those higher tides, or you might end up knee-deep in water before you know it!
