Using moon sign to determine compatibility with Astrology

Elemental compatibility in synastry readings

Published Nov 12, 2023

When looking at compatibility with astrology, one of the most important things to look at is the element of the moon sign for both individuals. The moon rules our emotions and our emotional intimate connections with others, so having a moon sign that is in the same element [as someone], or a compatible element with someone, means that you are more likely to be able to connect with them on an emotional level and be a place of emotional security and comfort for each other.

If you have an Aries, Leo or Sagittarius moon, that means your moon is in a fire sign. As an element, fire talks about activity, excitement, intensity, heat and passion. People who have fire moons tend to crave that spark, that excitement and passion that allows them to feel as though they're being emotionally supported and nurtured–so that their emotions are actually being heard and that they can express their emotions loudly and proudly without fear of judgment.

They're also very playful, so bringing play and fun and games into the relationship with the fire moon is going to help them feel more emotionally secure and supported and give them an outlet to express their emotions in a healthy way.

If you have a Gemini, Libra, or Aquarius moon, then your moon is in an air sign. The element air rules our mind, our words, and our speech, our communication. Air moons typically desire communication in order to satisfy their emotional needs. Being able to bounce ideas off of each other, share ideas, and explore those ideas together with curiosity, is going to help an air moon feel like they are being emotionally supported.

Air moons process their emotions with their mind and their words. So giving an air moon space to express their emotions through their words (if they desire) to is a great way to build an emotional connection with someone who has their moon in an air sign. They're very intellectual and being able to talk about intellectual subjects and stimulate their minds is going to help an air moon feel more emotionally connected to you.

Air moons and fire moons are very compatible emotionally. These elements are both masculine elements, fire and air, and they go together very well. The thoughts and ideas that come from air moons help to fuel the passion and creativity of fire moons, the way that air fuels a fire.

If your moon is in Cancer, Scorpio, or Pisces, then your moon is in a water sign. The moon rules our emotions and the element water is associated with the moon and our emotions. So people who have their moon in a water sign tend to be very in tune with their emotions, very intuitive and able to sense the emotions of others very well.

Water moons need to feel a deep emotional connection with someone before they're willing to put their guard down and really open up to their emotional vulnerabilities. Being very gentle and tender and nurturing with your water moon friend or partner is a great way to show them that you're on their team and that they can trust you, and open up to you emotionally.

Since their emotions are ruled by water, spending time near large bodies of water is a great way for water moons to reflect on their own emotions. The moon and water rule over the idea of a reflection and so water moons tend to reflect your own emotions back at you. They are people who match your energy.

If your moon is in Taurus, Virgo or Capricorn, then your moon is in an Earth sign. This means that your emotions, your emotional processing is directly related to your physical body and your experience on physical Earth. Earth moons may feel emotionally supported and nurtured through physical touch and sensuality. Acts of service to show them your physical support in this physical reality (and to give them some time off from their responsibilities so that they can focus on their emotional well being). And of course, financial support. In order for an Earth Moon to feel safe enough to open up their emotional vulnerabilities, they need to feel physically safe and financially secure in this physical reality.

And Earth Moons... are also very compatible with water moons. These are both the feminine elements, earth and water. Think of how life on earth depends on water for that life to grow and develop within. Earth moons are great at planting seeds to grow something of value, while water moons are great at watering those seeds so that that things can grow and develop and actually manifest.

Of course, this isn't the only way to determine compatibility with astrology. You could have a fire moon and an earth moon who are very compatible even though they might process their emotions differently. Same for an air moon and a water moon, etc.
