Really. The moon affects how much it rains.
Several independent studies by meteorologists show that the moon's phases affect the weather. Scientists studied eighty years' of data correlating rainfall amount and the moon's position. They found that when the moon's tidal pull is greatest, either a full or new moon, precipitation increases an average of twenty percent.
The exact mechanism isn't understood but it's thought that the moon's tidal pull on wind currents in the upper atmosphere is involved.
