A spring tide—popularly known as a "King Tide"—refers to the 'springing forth' of the tide during new and full moon. A neap tide—seven days after a spring tide—refers to a period of moderate tides when the sun and moon are at right angles to each other.

28 Σεπ 2024 · 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.
30 Απρ 2018 · Neap Tides: The Lowest Tidal Range. Neap tides, meanwhile, result from the moon and sun working against each other's pull. When the moon is in its first and third quarter phases, the earth, sun and moon form a right angle.
What is a neap tide? When the sun and moons are at right angles to each other, there is least gravitational pull, meaning the tidal range is at its lowest. The neap tide occurs 7 days after the spring tide.
Spring tides are characterized by the highest high tides and lowest low tides, occurring during new and full moons, while neap tides, with their less extreme tidal ranges, occur during the quarter moon phases.
20 Δεκ 2006 · The origins of neap–spring tidal cycles are not as simple as the equilibrium tidal theory implies and to understand them requires knowledge of both equilibrium and dynamic tidal theory and an understanding of tidal constituents.
Twice a month, when the Earth, Sun, and Moon line up, their gravitational power combines to make exceptionally high tides, called spring tides, as well as very low tides where the water has been displaced. When the Sun is at a right angle to the Moon, moderate tides, called neap tides, result.
