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.

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. A neap tide is where the sun and moon are at their least aligned point. Not to scale.
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.
Spring tides always happen when the Moon is at the full or new phase, which is when the Sun, Moon and Earth are in alignment. Neap tides occur around the first and last quarter phase of the Moon, when the Moon’s orbit around Earth brings it perpendicular to the Sun.
Neap tides occur seven days after spring tides, which are periods of high tides that occur when the sun, moon, and Earth are aligned. Neap tides occur during the first and third quarter moon phases, which happen roughly halfway between the full and new moon phases.
These tides are referred to as neap tides; a low tide or one that is lower than average. A neap tide happens between two spring tides and occurs twice a month when the first and last...
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.
