What influences the tides besides lunar and solar gravity?

Answer 1

Earth rotating speed and the tilted angle of rotation do contribute to different in magnitude of the tides and seasonal pattern of tide.

Because earth rotate, more of the water would centrifuge and bulge up around the equator and tide would rise more at the equator by average. The tilted axis, cause the center of the tide change seasonally, on northern hemisphere the summer tide maximum - minimum will be shifted above the equator and during winter the maximum - minimum will be below the equator.
