For some of you who don't believe it the FULL moon and the NEW moon do have an effect on the tides.

"The full-ness of the moon has absolutely nothing to do with the tides. The tide comes in and out because of the moon's constant gravitational pull on the Earth and the fact that the Earth is rotating around its axis. The section of Earth that faces the moon experiences a greater gravitational pull, and therefore the water rises."

Spring Tides
When the moon is full or new, the gravitational pull of the moon and sun are combined. At these times, the high tides are very high and the low tides are very low. This is known as a spring high tide. Spring tides are especially strong tides (they do not have anything to do with the season Spring). They occur when the Earth, the Sun, and the Moon are in a line. The gravitational forces of the Moon and the Sun both contribute to the tides. Spring tides occur during the full moon and the new moon.

So, once again if it can effect the water and the tide, why can't it effect us
