Not much of an answer, but Its something to do with the moon and gravity.
Hope that helps

High tides, low tides, spring tides (which are maximum high tides) and neap tides (which are the lowest of low tides).
Minimum tides are also known as low tides. It's the lowest a tide will get in the cycle of highs and lows.
A neap tide happens during the quarter phase of the moon and they are weak tides. There is a very small difference between high and low tides during this time.

tidal range
No, the greatest difference between low and high tides occurs during a spring tide, which happens when the sun, moon, and Earth are aligned. Neap tides occur when the sun and moon are at right angles to each other, resulting in smaller tidal range.
They consider high and low tides in their journey because if it is high tide the water level will be high but if it is low tides the water level is low.
Low tides
Tides that are not very high and not very low are called neap tides.
neap tides are moderate tides at normal rates while spring tides are more extereme ex to high or to low .
