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.

Spring tides are a type of tide that occurs when the sun, the moon, and the Earth align in a straight line, exerting their gravitational forces in the same direction. This alignment enhances the gravitational pull on the Earth’s oceans, resulting in higher high tides and lower low tides than usual.
Spring tide essentially is the two tides where the sea is at its most extreme; the highest and lowest. In contrast, a neap tide is one where the difference between the high and low tides is at its lowest.
Spring tides bring extreme high and low tides, while neap tides produce more moderate tidal fluctuations. Whether you’re a boater, fisherman, or just curious about the ocean’s behavior, understanding these tides and their cycles can help you make the most of coastal activities.
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.
When the sun and moon align, their gravitational forces combine to produce the very highest and lowest tides, called spring tides. When the sun and moon are at right angles, they pull at the sea from different directions and moderate tides, with a smaller range, form.
15 Ιουν 2024 · Spring tides have the highest high tides and the lowest low tides. They occur during the full and new moon phases. Neap tides have the least variation between high and low tides and occur during the first and third quarters of the moon's phase.
