Moon water is ordinary water that has been left out under the moon, usually overnight and usually at the full moon, so that it takes on the moon's light and the intention you set when you poured it. Witches use it the way other traditions use blessed water: to cleanse tools and rooms, to add to baths and floor washes, to anoint candles, to water plants, and, when it is made safely, to drink. It costs nothing, it takes five minutes of work and one clear night, and it is one of the first things most people learn to make.
This page covers what moon water is and where the idea comes from, which moon phase to use, the nights when it is better to skip, the step-by-step method, what to do with it once you have it, whether you can drink it, and how to store it.

What Is Moon Water?
Moon water is water that has been set out under the moon with an intention, and its purpose is to carry that intention into whatever you use the water for afterward. There is nothing chemically different about it the next morning. What changes is that you have made a plain jar of water into a tool: you chose the night, you spoke over it, and you decided what it was for. When you later add it to a bath or wipe down an altar with it, you are bringing that decision back into the room.
Most moon water is made at the full moon, because the full moon is the traditional peak of the lunar cycle and the easiest night to feel the pull of the practice. But you can make it at any phase, and the phase changes what the water is for. Full moon water is the all-purpose version; new moon water is for beginnings; the phases between have their own jobs, covered below.
If you have ever read that the moon controls the tides and thought that the same pull must do something to a jar of water, you are in good company, and it is worth being honest about it. The moon's tidal force acts on the whole ocean; it does not measurably do anything to a jar. Moon water works the way a candle or a written petition works: as a focus for attention and a marker of intention. That is not a smaller thing than chemistry. It is a different thing.
Where the Idea of Moon Water Comes From
Moon water comes from two very old ideas that modern witchcraft put together: that the moon is a living power worth working with, and that water can be blessed and set apart for sacred use. Neither idea needs a footnote to feel true, but both have long histories.
The first is lunar worship. Nearly every ancient culture personified the moon and kept a calendar by it; the Greek Selene drove the moon across the sky in a chariot, and Hecate, goddess of crossroads and witchcraft, took on lunar associations that modern witches still lean on. The lunar month is the oldest unit of time longer than a day that humans agreed on. Folk belief that the moon affects sleep, mood, births, and crops, what researchers call the lunar effect, is found on every continent, whether or not it survives a controlled study.
The second is blessed water. Holy water in Christianity, the lustration rites of Greece and Rome, and the broad family of ritual purification practices in Judaism, Islam, Hinduism, and Shinto all rest on the same move: take water, set it apart with words and gesture, and use it to make people, places, and objects clean in a way that soap cannot reach. Moon water is a witch's version of that move, with the moon standing in for the priest.
The specific practice of leaving a jar out under the full moon is modern. It grew up with twentieth-century Wicca and eclectic witchcraft, spread through the books of the 1990s and 2000s, and went everywhere on social media in the 2010s. That does not make it less real. It makes it yours to shape.
Full Moon Water, New Moon Water, and the Phases Between
Full moon water is for charging, cleansing, and anything you want at full strength, and new moon water is for beginnings and quiet intention-setting; the phases in between narrow the purpose further. Here is how the cycle maps onto the jar:
| Phase | What the Water Is For | Notes |
|---|---|---|
| New moon (dark moon) | New moon water is for beginnings: a new project, a new habit, a fresh start after a hard month, and for quiet inner work like shadow work and rest. | There is no visible moon, so the jar sits in the dark. Some witches skip the dark moon and make it a day or two later at the first crescent. Both are common. |
| Waxing crescent to first quarter | Waxing moon water is for growth and drawing things toward you: money, opportunities, courage, momentum on something already begun. | Good for watering plants and for the "grow" side of any spell. |
| Waxing gibbous | Waxing gibbous water is for refining and pushing through the last stretch of a goal. | Useful the week before a deadline or a hard conversation. |
| Full moon | Full moon water is the all-purpose version: cleansing, charging tools, ritual baths, blessing, and manifesting. | This is the default. If you only make moon water once a month, make it now, and see our list of things to do during a full moon for what else the night is good for. |
| Waning gibbous to last quarter | Waning moon water is for releasing, banishing, and letting go: ending a habit, cutting a cord, clearing a room after an argument. | Pair it with black salt for a floor wash that clears a space. |
| Waning crescent (balsamic) | Waning crescent water is for rest, endings, and protection while you regroup. | Some witches use it only for cleansing and never for drinking, on the theory that you do not want to take "release" into the body. |
The full and new moons also carry the sign the moon is in that night, and many witches label the jar with it. A full moon in Cancer makes water that feels right for home and family work; a full moon in Scorpio suits shadow work and transformation; a new moon in Virgo suits organizing and health routines. Our page on how to use the moon phases for spells goes deeper on timing, and the moon calendar tells you tonight's phase and sign.
Special moons are worth a label of their own. A blue moon (the second full moon in a calendar month) is treated as a rare, extra-potent night for wishes. A supermoon, when the full moon is closest to Earth, is the same. The harvest moon in September or October is traditional for gratitude and abundance water.
When Not to Make Moon Water
Most witches skip making moon water during a lunar eclipse, and many also skip it when the moon is void-of-course, when they are sick or upset, and when the weather will not let the jar sit out safely. None of these are laws; they are the working rules that have settled in over the last few decades, and it helps to know the reasoning so you can decide for yourself.
- Lunar eclipses. A lunar eclipse happens at a full moon when the Earth's shadow crosses the moon, and the widespread rule is not to make moon water that night. The reasoning is that eclipse energy is chaotic and about endings, and you do not want to bottle it. A minority of witches make eclipse water on purpose for banishing and shadow work and label it clearly. If you are new, skip it; if you are experienced and want it, know what it is for.
- Void-of-course moon. In astrology, the moon is void-of-course during the hours after it makes its last major aspect in one sign and before it enters the next. The tradition says things started during a void moon "come to nothing," so witches who work with astrology avoid starting the jar then. If you do not follow astrology, ignore this one entirely. It is a timing refinement, not a foundation.
- When you are sick, exhausted, or furious. Moon water carries the state you were in when you made it. A jar poured in a bad mood is a jar you will not want to drink from or wash with later. Wait a night, or make it and label it "banishing."
- When the weather will ruin it. A glass jar left out in freezing temperatures can crack as the water expands. Heavy rain will dilute an open bowl and fill it with debris. A windy night knocks jars over. Use a windowsill instead; see the FAQ on whether glass gets in the way.
- When you cannot keep it clean. If the only spot you have is where pets, birds, or insects can reach the water, do not make drinking water there. Make it covered, or make it for cleansing only.
Cloudy nights are fine. The moon is still up there, and the water is about intention, not photons. Waning moons are fine too, as long as you make the water for waning-moon purposes.
What You Need for Moon Water
You need a clean glass container, water, and a place where moonlight lands, and everything else on this list is a choice. Here is the full kit:
- A glass jar or bottle with a lid. Mason jars are the standard. Glass, not plastic, because glass does not hold flavors or leach, and because it looks like what it is. Use a lid if you plan to drink the water. An open bowl is traditional and fine for cleansing water.
- Water. Filtered, spring, or bottled water if you will drink it. Tap water is fine for cleansing water and for plants. Rain water and stream water are lovely for spell work and off-limits for drinking unless boiled first.
- A white candle. Lit while you pour and speak over the water. White stands for the moon, purity, and any intention at all; our candle color guide explains why, and white candles are the one color worth keeping a box of.
- Salt. A pinch for purification, added to cleansing water only. Skip it in water you plan to drink or give to plants.
- Herbs and petals, optional. Rose petals for love and self-love, lavender for peace and intuition, rosemary for cleansing and memory, mint for money. Add them to cleansing and bath water. For drinking water, add them only if they are food-grade and only if you will drink the water within a day or two; herbs in water go off fast.
- Crystals, optional, beside the jar. Set clear quartz, moonstone, or selenite next to the jar, not in it. Selenite dissolves in water, malachite and pyrite leach compounds you do not want to drink, and even "safe" stones carry dust and polish. Beside the jar does the same work with no risk.
- A label and a pen. Date, phase, sign, and purpose. A month from now you will not remember which jar was which.
- A mirror, optional. Set the jar on a small mirror to double the moonlight. Old folk touch, nice to look at, entirely optional.
How to Make Moon Water, Step by Step
Making moon water takes five minutes at dusk and two minutes at dawn, and the whole ritual is below:
- Check the moon. Confirm tonight's phase and sign on the moon calendar, and confirm it is not a lunar eclipse. Decide what the water is for before you touch the jar.
- Wash the jar. Hot water and soap, rinsed well, no residue. If the water is for drinking, dry the jar with a clean towel or let it air-dry upside down.
- Fill it. Filtered or spring water for drinking; tap or rain water for cleansing and plants. Leave an inch of space at the top.
- Add what belongs. A pinch of salt for cleansing water. Petals or herbs for bath and spell water. Nothing at all for drinking water unless it is food-grade and you will drink it within two days. Crystals go beside the jar, never in it.
- Light the white candle and speak over the water. Hold the jar or rest your hands on it and say what the water is for out loud. Use the charge in Words to Say or your own. Keep it to a few sentences; the moon is doing the long part.
- Set it under the moon. Outdoors on a table, a step, or the ground where moonlight actually falls, or on a windowsill that faces the moon. Put the lid on if the water is for drinking. Leave it open if it is for cleansing and the night is dry and still.
- Leave it overnight. The traditional minimum is until the moon sets or until you go to bed. Overnight is standard. An hour under the moon is enough if that is all the night allows.
- Bring it in before sunrise. Most witches collect the jar before the sun touches it, on the belief that sun energy overrides moon energy. It also keeps a clear jar of water from acting as a lens in morning sun, which can scorch a wooden table or dry grass.
- Label it. Date, phase, sign, purpose. "Full Moon in Pisces, Sept 2026, cleansing."
- Store it. Lid on, cool and dark. See How to Store Moon Water for how long it keeps.
Words to Say Over Moon Water
Say one short charge over the jar while the candle burns, and keep it plain, because the water does not need convincing. Here is one you can use or adapt:
Water of the earth, light of the moon,
hold what I ask and give it back to me.
I make this water for [cleansing / new beginnings / love / release].
Take the moon's light tonight, and keep it.
For a full moon, some witches add the name of the moon, "Harvest Moon" or "Wolf Moon," from the full moon names. For a new moon, a single sentence is enough:
This is the beginning. I set it here.
And when you collect the jar in the morning, a closing line marks it done:
Charged and kept. Thank you.
You do not have to speak aloud. A written intention on the label does the same job, and so does silence with your hands on the glass.
What to Do With Moon Water
Moon water goes into anything you want to carry the moon's intention: cleansing, baths, floor washes, anointing, plants, offerings, and drinking. The most common uses, with specifics:
- Cleanse altar tools and crystals. Wipe your athame, wand, and altar surface with a cloth dampened in full moon water at each full moon. For crystals, sprinkle a few drops or wipe; do not soak porous or soft stones (selenite, malachite, calcite, pyrite, hematite) because water damages them.
- Add it to a ritual bath. Pour a cup into the bath along with a handful of sea salt and a few rose petals. Our aura cleansing bath ritual gives the full method. Use cleansing-purpose water for cleansing baths and love-purpose water for self-love baths.
- Make a floor wash. Add a cup of moon water to a bucket of mop water, with a splash of Florida Water for a fresh, clearing scent. Mop from the back of the house toward the front door to move stale energy out. Waning moon water is best for this.
- Fill a spray bottle. Moon water with a sprig of rosemary or a few drops of lavender oil makes a room and linen spray for clearing a space before ritual, before sleep, or after an argument. Shake before each use and remake it every two weeks.
- Anoint candles and yourself. Dab full moon water on a candle before lighting it for any full moon spell, such as the full moon self-love spell or the silver coin money spell, or on your wrists and the back of your neck before meditation or divination.
- Water plants. Waxing or full moon water for houseplants and the garden is the gentlest use there is, and it pairs with moon phase gardening. Skip salted water for plants.
- Use it for manifesting. Write the intention on the label, drink a sip of drinking-grade water each morning while you picture the outcome, or use it to water a plant that stands for the goal. The water is a daily reminder; the picturing is the work.
- Leave it as an offering. A small bowl of full moon water on the altar for a lunar deity, an ancestor, or the spirits of the house. Change it at each full moon and pour the old water onto the earth.
- Bless a threshold. A few drops on the front doorstep, or a line of it across the threshold, at the new moon for a fresh start or at the full moon for protection.
- Drink it. Covered, potable, unsalted, un-herbed or food-grade only. Details in the next section.
Can You Drink Moon Water?
Yes, you can drink moon water if it was made with drinkable water in a clean, lidded container and nothing was added to it that you would not put in a glass of water anyway. The moon does not make water unsafe. What makes water unsafe is what gets into it, so the rules are practical:
- Start with potable water. Filtered, spring, or bottled. Tap water is fine if your tap water is fine. Never drink rain, stream, pond, or dew water without boiling it first.
- Keep the lid on. An open jar outdoors overnight collects insects, pollen, dust, bird droppings, and curious cats. Moonlight goes through glass. Put the lid on.
- No salt, no crystals, no non-food herbs. Salt makes it undrinkable in any real quantity. Crystals belong beside the jar (see What You Need). Only add herbs that are sold as food or tea, and drink that water within two days.
- Drink it within a few days. Plain, lidded moon water is just water and keeps as long as any stored water, but the point of drinking it is the intention, and intention fades from memory. A week is plenty. Herb-infused water goes in the refrigerator and is used or discarded within two days.
- If it looks or smells off, pour it on the earth. Cloudy water, floating specks, or a sour smell mean it is cleansing water now, or garden water, not drinking water.
Drinking moon water is a way of taking an intention into the body and marking a small daily practice. It is not a supplement and it does not treat anything; the water is the same water it was, and the practice is the point.
How to Store Moon Water
Store moon water in a sealed glass jar in a cool, dark place, labeled with its date and purpose, and use it within a lunar month. Here is the reasoning:
- Sealed glass. A lid keeps dust and evaporation out and keeps the water from picking up smells. Glass over plastic.
- Cool and dark. A cupboard or a shelf away from windows. Many witches keep moon water out of direct sunlight on principle, and a jar of water in a sunny window can also act as a lens and start a fire on a wooden sill. That is a real hazard with clear jars of water, not a superstition.
- Refrigerate anything with herbs. Petals and leaves in water start to break down within a day or two at room temperature. Refrigerate, and use within two days or pour it out.
- Use it within a month. Plain moon water does not spoil quickly, but the custom is to use each month's water before the next full moon and make a fresh jar. Pour any leftover onto the earth or into a plant, with a word of thanks.
- Label everything. Phase, sign, date, purpose. Unlabeled jars turn into mystery water within a week, and mystery water is cleansing water by default.
- Keep it away from the altar's black-salt dish. Moisture cakes the salt.
Moon Water FAQ
What is moon water?
Moon water is water that has been left out under the moon, usually overnight at the full moon, with a spoken or written intention. Witches use it for cleansing, ritual baths, floor washes, anointing, plants, and, when it is made with clean drinkable water in a lidded jar, for drinking.
How do you make moon water?
Fill a clean glass jar with water, add a pinch of salt (for cleansing water only), light a white candle, say what the water is for, and set the jar outside or on a windowsill under the moon. Leave it overnight, bring it in before sunrise, label it with the date and phase, and store it sealed in a cool, dark place.
What does moon water do?
Moon water carries an intention into whatever you use it for. It cleanses tools and rooms, charges a bath or a floor wash, anoints candles for spellwork, feeds plants, and serves as an offering. It does not change chemically under the moon; its power is the focus and intention you give it.
Can you drink moon water?
Yes, if it was made with filtered, spring, or bottled water in a clean jar with the lid on, and nothing was added except food-grade herbs. Do not drink water that sat open outdoors, water with salt or crystals in it, or rain, stream, or dew water that has not been boiled.
Is moon water witchcraft?
Moon water is a witchcraft practice, and it is also used by people who would not call themselves witches. Blessing water for sacred use is found in Christianity, Judaism, Islam, Hinduism, and Shinto, and working with the moon is older than any of them. If you make moon water, you are doing a small, old, and widely shared thing.
When should you not make moon water?
Most witches skip lunar eclipses, because eclipse energy is considered chaotic and about endings. Many also skip the void-of-course moon if they follow astrology, nights when they are sick or angry, and nights when freezing weather or rain would damage the jar. Cloudy nights are fine.
What is the difference between full moon water and new moon water?
Full moon water is the all-purpose version, used for cleansing, charging, baths, and manifesting at full strength. New moon water is for beginnings, quiet intention-setting, and inner work, and it is made in the dark because there is no visible moon that night.
How do you store moon water?
In a sealed glass jar, labeled with the date, phase, and purpose, in a cool, dark cupboard. Use plain moon water within a lunar month and refrigerate any water with herbs in it, using it within two days.
Does moon water have to be made at a full moon?
No. The full moon is the traditional and most common night, but every phase makes usable water with a different purpose: waxing for growth, waning for release, new for beginnings.
Can you make moon water through a window?
Yes. Moonlight passes through glass, and a windowsill facing the moon works. It also keeps the jar safe from weather and animals, which makes it the better choice for drinking water.
Does it work if the night is cloudy?
Yes. The moon is still in the sky whether or not you can see it, and the water is charged by the phase and your intention, not by visible light. Make it as usual and label it as usual.
Can I use tap water for moon water?
Yes for cleansing water, plants, and floor washes. For drinking, use filtered, spring, or bottled water unless your tap water is water you already drink.
If you track your cycles, note the moon water on the full moon row of a moon journal; our guide includes a free printable page.
