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 · 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.
Driven by gravitational forces, tides affect ecosystems, coastal navigation, and human activities. Let’s explore high and low tides, the unique behavior of spring and neap tides, and the thrilling event known as a tidal bore.
20 Δεκ 2006 · Neap tides occur when the Sun and Moon are aligned at right angles from the Earth at first- and third-quarter phases of the Moon. The result is that spring tides are higher than neap tides (Fig. 1 E). The period of time from new Moon to new Moon is called the synodic month, which has a modern period of 29.53 days.
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 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.
