The greatest tidal extremes occur when the Sun, Moon, and Earth
are all lined up along the same straight line. Those occasions are
at the time of the Full Moon ... when the Earth is the middle one ...
and the time of the New Moon ... when the Moon is the middle one.
Those are the occasions of the highest high tides and the lowest
low tides, known collectively as "Spring tides".
The smallest tidal extremes occur when the Sun, Moon, and Earth
form a right angle, with the Earth at the vertex. Those occasions are
at the time of the First Quarter and Third Quarter Moon. Those are
the occasions of the highest low tides and the lowest high tides,
known collectively as "Neap tides".
