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.
30 Απρ 2018 · A high tide occurs at the two bulging points and a low tide at the two points halfway between because the water is being redirected. Each location on the earth passes through these points twice a day, usually experiencing two high and low tides daily.
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.
20 Δεκ 2021 · Neap tides occur when the effect of the tidal forces of the sun and the moon on the tidal bulges cancel each other. Figure 3.22 shows an example of these tidal variations. Figure 3.22: Tidal variation in Vlissingen during more than a month in 2019.
Neap tides are a type of tidal pattern that occurs twice a month, during the first and third quarters of the moon. During neap tides, the difference between high and low tide is at its minimum. This phenomenon happens due to the gravitational pull of the sun and the moon on the Earth’s oceans.
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.
