    The plane of moon's orbit around the earth is at an angle to the equator, called the declination. The result of this angle is that one tidal bulge is centered in the southern hemisphere and one in the northern hemisphere. Certain places in mid latitudes then experience a single tide each day (actually separated by about 25 hours) known as diurnal tides. Other places have two equal tides each day known as semi diurnal tides. Where one tide is higher than the other it is known as a mixed tide.

    Diurnal tides occur in the Gulf of Mexico, the west coast of Alaska, and in Torres Straights in December and June.

    Its hard to explain the diurnal tide without a diagram. The best diagram I know is on the last page of the first link.

    Thomas, there are normally two high tides and two low tides in a month caused by the effects of the Moon on the Earth's oceans, and a corresponding wobble effect the Moon causes on the Earth. (The Sun is in on this a bit, too).

    Now, are you saying that, because of the shape of the Gulf, that the secondary high tide (near New Moon) never generates. That may be more a result of flow restriction.
