Depending on where you live, you have high tides about every 12 hours, no matter what the phase of the Moon.

However, at the full and new moons, you have higher-than-average "spring" tides, because the gravitational pull of the Moon lines up with the much lower gravitational pull of the Sun.

At the quarter moons, we have lower-than-average "neap" tides because the tidal pull of the Moon and the tidal pull of the Sun are working at cross-purposes.
