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. A spring tide is a common historical term that has nothing to do with the season of spring.

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. A neap tide is where the sun and moon are at their least aligned point. Not to scale.
Spring and neap tides are unique tidal phenomena that occur twice a month, driven by the alignment of the sun, moon, and Earth. Spring tides bring extreme high and low tides, while neap tides produce more moderate tidal fluctuations.
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.
Spring high tides are higher and spring low tides are lower than average. Neap tides occur when the moon is at its first or third quarter. Now the lunar tide and solar tide cancel each other out, leading to a smaller tidal range than average. The spring-neap cycle causes tides to build to a maximum and fall to a minimum twice each month.
