A tidal pattern of two equal high and low tides per day is called a semidiurnal tide. A mixed semidiurnal tide has two high and two low tides, but with varying heights. A diurnal tide has only one high and one low tide per day, while spring and neap tides refer to the monthly variation in tidal heights.
