The predictions are influenced by many factors including the alignment of the Sun and Moon, the phase and amplitude of the tide (pattern of tides in the deep ocean), the amphidromic systems of the
Full moon Psychologists, however, have found that there is no strong evidence for effects on human behavior around the time of a full moon.
