What does the term "mixed tides" refer to?

The term "mixed tides" specifically refers to a tidal pattern that exhibits characteristics of both diurnal and semi-diurnal tides. In areas with mixed tides, you typically experience two high tides and two low tides each lunar day, but the heights of these tides vary significantly. This variability is a key distinguishing feature of mixed tides, which sets them apart from strictly diurnal (one high and one low tide per day) and semi-diurnal (two high and two low tides of approximately equal height) patterns. The presence of mixed tides is prominently noted in certain coastal regions where geology and local conditions influence tidal behavior, leading to a diverse tidal rhythm. Understanding this concept is essential for navigation and seamanship, as it affects coastal currents and the timing of navigation operations.
