Semidiurnal is the daily tidal pattern occurs along the northeast us coast
Along the principal shorelines of the planet, there are three primary tidal patterns. There are typically two high tides and two low tides every day in most places. A semi-daily or semidiurnal tidal pattern is one where the heights of the two highs and lows are roughly equal. A mixed semidiurnal tidal pattern is one in which the heights of the high and low tides vary.
Certain regions, like the Gulf of Mexico, only see one high tide and one low tide each day. It is known as a diurnal tide. Mixed semidiurnal tides are more common along the U.S. West Coast than a semidiurnal pattern along the East Coast.
