The weather and both solar and lunar activity are known to play a role in increased paranormal activity. Since the moon has such an effect on water and the tides, it is surmised that there is increased paranormal activity when the moon is full.  There is a close connection between paranormal activity and the proximity of water -- the moon controls the tides, and has even been proven to have an effect on both animals and humans.

Thus, in regards to the lunar cycles, there seems to be more paranormal activity during the new and full moon periods.
