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.
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.
19 Οκτ 2023 · Causes of Tides. Forces that contribute to tides are called tidal constituents. The Earth’s rotation is a tidal constituent. The major tidal constituent is the moon ’s gravitational pull on the Earth. The closer objects are, the greater the gravitational force is between them.
One week later, when the sun and moon are at right angles to each other, the solar tide partially cancels out the lunar tide and produces moderate tides known as neap tides. During each lunar month, two sets of spring and two sets of neap tides occur.
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.
Neap tides. When there is a low tide, the Moon faces the Earth at a right angle to the Sun so the gravitational force of the Moon and Sun work against each other. These tides are referred to as...
