What is a king tide?

What causes a king tide?
The tides happen when there is an alignment of the gravitational pull between the sun and the moon in the Northern Hemisphere, according to the National Oceanic and Atmospheric Administration.
"Twice a year when the earth, sun and moon line up, when the moon and the sun are at perigee and perihelion, we generally experience the greatest tidal ranges of the year," according to the North Carolina King Tides Project.
What are perigee and perihelion?
Perigee is the name of the point when the moon is near to the earth.
Perihelion means a point in the orbit of a planet (in this case Earth), asteroid or comet that is nearest to the earth sun.
A few times a year, in the spring and fall, the new or full moon coincides with the perigee of the moon.  During full or new moons average tidal ranges are larger. A new or full moon occurs when the sun, earth and moon are in near alignment.
