Full Moon and New Moon phases.
The sun and the moon's gravity pull in the same direction .
the moon is at new or full moon phases in other words between earth and sun, or 'behind' earth. This is because the gravitational pull works with the sun.
"Spring" tides, which are a little higher than average, occur at new moons and full moons. "Neap" tides, a little lower than average, occur at the quarter moon phases.
Spring tides
Spring tides occur when the Sun, Moon, and Earth all lie in a line, more or less... in other words, at New Moon and Full Moon. This is because at these times the tidal forces on Earth from the Sun and Moon reinforce each other.
Only spring and neap tides. The normal day to day tides are brought about by the position of the moon in relation to the earth as the earth rotates 'beneath' it
the relative positions of Earth,moon,and sun(the phases of the moon)
The sun and the moon's gravity pull in the same direction .
Spring tides are caused by new and full moons. Neap tides are caused by 1st and 3rd quarter moons.
the moon is at new or full moon phases in other words between earth and sun, or 'behind' earth. This is because the gravitational pull works with the sun.
Spring tides, which are a little higher than normal, occur at the new and full moon phases.
Higher-than-average "spring" tides occur at the new moon and full moon phases. Lower-than-average "neap" tides happen at the quarter-moon phases.
Spring tides (which are a little higher than average) occur when the Sun, Moon and Earth are pretty much lined up; at the new moon and the full moon. Lower-than-average "neap" tides happen at the 1st and 3rd quarter moon phases.

Spring tides
When the Sun, Earth and Moon are nearly lined up, the Sun and Moon's gravitational effects on tides are amplified slightly, causing higher-than-average 'spring tides". This happens at the new and full moon phases. When the Moon is at right angles to the Sun-Earth line, at the first and third quarter moon phases, we have lower-than-average "neap" tides.
