We notice that the tides do not change the water level as much as they do on Nantucket. We guessed that since we are so close to the equator, it must have some affect. We looked up “Do tide levels vary with latitude?” and this is what we found.
“Yes, near the equator tidal influence is the lowest. This is related to the geometry of the moon's orbit in relation to earth, and the tilt of the earths axis.
Consider the plane of the earth's orbit around the sun as a fixed plane. This is known as the ecliptic. The earth's axis is on a tilt of 23.5 degrees to this plane, which is the tilt that produces the seasons. Also because of this tilted axis of rotation, there is a more pronounced effect of both the sun and the moon's tidal force at middle and higher latitudes.”
