Moon sign compatibility: what each of you needs to feel safe

Moon sign compatibility describes how two people's emotional needs meet: what each of you needs to feel safe, and how each of you calms down. Moons in the same element (fire, earth, air or water) tend to feel easy, because you look for comfort in a similar way. Moons in different elements can work just as well. They take more explaining, and no pair of Moon signs is ruled out.

What your Moon sign does in a relationship

Your Moon sign is the zodiac sign the Moon stood in when you were born. Astrologers read the Moon as your feelings and needs: what settles you, what unsettles you, and what you reach for when you are tired, worried or hurt. How to find your Moon sign

In the early days of a relationship the Moon is easy to overlook. It shows once daily life begins: on the evening after a bad day, in the hour after an argument, in how each of you wants a weekend to feel.

One pattern explains most of what Moon signs do between two people. You tend to offer the comfort your own Moon would want. Someone with an Aries Moon suggests going out and doing something. Someone with a Cancer Moon wants to stay in and be held. Each means well, and each can feel that the other missed the point.

Most Moon sign friction is kindness in the wrong language: each of you offers the comfort you would want yourself.

Moon signs by element: what each needs to feel safe

The twelve signs fall into four elements, three signs each. The element is the quickest way to describe what a Moon needs.

Within one element the three signs still differ. A Taurus Moon holds on to comfort, a Virgo Moon to order and a Capricorn Moon to control. The table gives the shared ground.

Why the same Moon element feels easy

Signs of the same element sit 120 degrees apart on the zodiac, the circle of twelve signs. Astrologers call this angle a trine and read it as the easiest contact between two points. With two Moons it means that neither of you has to explain why you need what you need.

Easy is not the same as complete. Two Moons of one element also share a blind spot:

• Two fire Moons can heat each other up, and nobody slows down.
• Two earth Moons can settle into routine and leave feelings unsaid.
• Two air Moons can discuss a feeling at length without quite having it.
• Two water Moons can pull each other into the same mood.

Two more pairings are read as naturally friendly: fire with air, and earth with water. Fire and air Moons both recover by turning outward. One acts, the other talks. Earth and water Moons both recover by staying close to what is familiar. One does something practical, the other seeks closeness. Opposite signs, such as Aries and Libra or Taurus and Scorpio, always belong to these pairs.

When your Moon elements differ

Four combinations take more translation. That is a description of effort, not a warning.

A different Moon also brings what yours lacks. A water Moon can teach a fire Moon to stay with a feeling. An earth Moon can give an air Moon somewhere to land. Astrologers read these pairs as more work at the start and more range later, and how it turns out is up to the two of you.

The Moon is one contact among many

Comparing two Moon signs is a first sketch. Three things refine it.

• Degrees. Two Moons in water signs are only a close trine if their degrees are close as well. The Moon moves through a sign in about two and a half days, so its exact degree needs the birth time.
• Other contacts to the Moon. Your Moon also meets your partner's Sun, Venus and Saturn. How synastry aspects are read
• The rest of both charts. Venus and Mars describe attraction, and Saturn describes commitment. How two birth charts are compared

What to do next with your two Moon signs

Look up both Moon signs, then put the charts aside and ask each other three questions.

1. When you are upset, what helps most: company, quiet, a conversation or something to do?
2. What do I do with good intentions that does not help you?
3. How can I tell that you need comfort when you do not say it?

Compare the answers with the table. Where they match, you have a shorter way of saying it. Where they do not, the answers count and the table does not.

If you would like both charts read together, a Compatibility Reading compares your chart with your partner's, calculated from both sets of exact birth data. It describes tendencies and gives no verdict about whether you match.
