<p>A map highlights tidal patterns, with red lines for diurnal tides, blue for semidiurnal, purple for mixed. Diurnal tides in Gulf of Mexico, Bering Sea; semidiurnal in North Sea, Bay of Bengal; mixed in various coastal regions globally.</p>

<p>Tidal patterns throughout the world. A diurnal tidal pattern has one high tide and one low tide each lunar day. A semidiurnal tidal pattern has two high tides and two low tides each lunar day. A mixed tidal pattern may have characteristics of both diurnal and semidiurnal tides. Successive high tides and/or low tides will have significantly different heights.</p>
