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.
Tides result from a gravitational tug-of-war between Earth, the Moon, and the Sun. The Moon's gravitational force is slightly stronger on the side of Earth that is closer to the Moon than it is on the side of Earth that is farther from the Moon.
