Spring - Spring tide occurs when the Sun and the Moon are aligned to combine for the largest tidal range of the highest high tide and the lowest low tide. Neap - A neap tide is when the tidal range is at its smallest.

Neap tides only occur when the sun and moon are at right angles to each other. A spring tide occurs when there’s a new or full moon. Because it follows the moon’s lunar cycle, a spring tide happens twice per month. With the moon and sun roughly aligned the tides of Earth are on average slightly larger than usual.
What are spring and neap tides? Ocean tides on Earth are controlled by the gravitational pull of the moon and sun. Tides are affected by the annual and monthly orbits of these bodies. Spring and neap tides are connected to the phases of the moon. Spring tides occur all year round, twice each lunar month.
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.
19 Οκτ 2023 · The combined pull can cause the highest and lowest tides, called spring tides. Spring tides happen whenever there is a new moon or a full moon and have nothing to do with the season of spring. (The term comes from the German word springen, which means “to jump.”)
What are spring tides? Flexi Says: Spring tides have the largest tidal range, which is the difference between the high tide and the low tide. This occurs when the gravitational forces of the Sun and the Moon are aligned, which happens during a full moon or a new moon.
