Wet and Dry Moons

What is a Wet moon?
What is a Dry moon?
What is a Cheshire Moon?

  • A wet and dry moon are both crescent moons but with different angles to the horizon.
  • The crescent moon in the summer time appears on an angle to the horizon, like a backward C, that you can picture it not being able to hold water, or if it was holding water previously, it is now pouring it out.
  • In winter the moon is a more parallel with the horizon, like a U, and you can picture it being able to fill up with water. The moon Winter moon is also called a Cheshire moon – because it looks like Alice in Wonderland’s Cheshire cat’s smile.
  • There is some confusion over which way around the definition or a wet and dry moon should be.
  • Wet/Dry Moon Definition One: The wet moon is the winter moon because it looks like a bowl which could fill up with the rain of winter – so the moon is wet. As the moon starts to turn onto its side in summer it looks like the moon is pouring out its water, making the moon dry.
  • Wet/Dry Moon Definition Two: The wet moon is the summer moon because it is pouring water on the earth. As it starts to sit flat again in winter, it holds back the water and does not pour it on the earth, making it a dry moon OR it is empty so does not tip over. This definition is a part of Hawaiian mythology and astrology.
  • The reason for the changing angle of the crescent moon is because the Earth changes its tilt relative to the plane in which the moon orbits.
  • The path and angle of the moon is flipped left to right in the Southern Hemisphere compared to what the Northern Hemisphere sees.
  • Wet and dry moons have nothing to do with actual water on the moon or the moon causing any wet effects on earth.
