   The relative strength of the centrifugal hump depends a great
deal on your delclination (latititude).  Since the Earth is spinning
on it's pole, a point on the equator is farther from the center of
spin than a point near a pole.  This causes tides in different areas
to have different effects.

   For example, the tides on the U.S. west coast have two peaks daily.
The difference in height between the two peaks differs from day to
day---sometime the peaks are the same height, sometimes the peaks
have several feet of difference between them.

   Local geography also affects tides greatly.
