neap tide

neap tide

      tide of minimal range occurring near the time when the Moon and the Sun are in quadrature. This condition is geometrically defined as the time at which the line from the Earth to the Moon is at right angles to the line from the Earth to the Sun. Thus, the tide-producing effects of the Sun and the Moon cancel each other, and tidal ranges are usually 10 to 30 percent less than the mean tidal range. See also tide.
