King tides occur when the orbits and alignment of the Earth, moon, and sun combine to produce the greatest tidal effects of the year. See a story map from NOAA's Office for Coastal Management and The King Tides Project to learn about sea level rise and tidal flooding. King tides flood Manasquan, New Jersey, 2013.
Ocean tides are caused by the gravitational pull of the Moon and Sun. Due to the rotation of the Earth, locations will experience two high and two low tides each day. An alignment of the Sun and Moon will result in more extreme tides, known as spring tides.
