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.
What causes the tides? It is the gravitational attraction of the sun and moon that cause waters of the ocean to raise and lower at different parts of the earth. Tides occur in oceans, and to a much smaller extent, tides also occur in large lakes, in the atmosphere, and within the solid crust of the earth.
