Tides on Earth are influenced not only by the phase of the moon, but also by the "latitude" of the moon - or where the moon is in space compared to Earth. Whether the moon is closer to being above Earth's equator or one of the tropics will affect how one high tide compares to the next and how one low tide compares to the next. And when the moon is at the tropics or higher in latitude - even the number of tides that occur during the day can be affected.

Diurnal Tides:

 * Has a period or cycle of around one tidal day
 * They are classified as diurnal when there is one high tide and one low tide in a tidal day
 * During Tropic Tides (when moon is near tropics), the tides at high latitudes are diurnal
 * The moon is above the tropics or a at higher latitude during a diurnal tide
 * This is the most uncommon tide



Semi-Diurnal:

 * These are tides that go through two cycles during a single earth rotation
 * When two high waters and two low waters of a tidal day are around the same height
 * During Tropic Tides, the tides near the equator are Semi-Diurnal
 * The moon is at the equator
 * This is the second most common tide





Mixed Tides:

 * Mixed tides are two unequal high waters and two unequal low waters each tidal day
 * Could be a transitional tide occurring between a semi-diurnal tide and a diurnal tide
 * During Tropic Tides, the tides at middle latitudes are mixed
 * The moon is somewhere between being above the equator and somewhere above the tropics
 * This is the most common tide
