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.
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.
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.
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.
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. Let's start with spring tides.
Tides are the regular, alternating rise and fall of sea level caused by the gravitational pull of the moon and sun. The changing of the tide is often rapid and dramatic. On a smaller scale, similar motions occur on large lakes, in the atmosphere, and even within the solid earth.
