The Cold Moon is December's full moon, and in 2026 it peaks at 01:28 UTC on Thursday 24 December. In eastern Australia that is 12:28 pm on Christmas Eve, so the year's coldest-sounding moon reaches fullness at lunchtime, in summer, while you are probably queueing for prawns. It is also the closest full moon of 2026, a genuine supermoon, and, on the American almanac calendar, a name that only moved to December fairly recently. Here is the exact timing for every Australian time zone, where the name comes from, and what a "Long Night Moon" means when it rises two days after our longest day.
When is the Cold Moon in 2026?
NASA's table of lunar phases gives the December 2026 full moon as 01:28 Universal Time on Thursday 24 December. Daylight saving is running in New South Wales, Victoria, South Australia, Tasmania and the ACT, and not in Queensland, Western Australia or the Northern Territory (NSW Government), so here is how that lands:
| Where | Time zone | Full moon peak |
|---|---|---|
| Universal Time | UTC | Thu 24 Dec, 1:28 am |
| Sydney, Melbourne, Canberra, Hobart | AEDT (UTC+11) | Thu 24 Dec, 12:28 pm |
| Adelaide | ACDT (UTC+10:30) | Thu 24 Dec, 11:58 am |
| Brisbane | AEST (UTC+10) | Thu 24 Dec, 11:28 am |
| Darwin | ACST (UTC+9:30) | Thu 24 Dec, 10:58 am |
| Perth | AWST (UTC+8) | Thu 24 Dec, 9:28 am |
Every Australian time zone gets the peak in daylight, when the moon is below the horizon (a full moon sits opposite the Sun, so a midday Sun means a moon on the other side of the planet). That is not a problem. The moon looks full for a night either side, so watch it rise around sunset on Wednesday 23 December or on Christmas Eve, Thursday 24 December. If the 23rd is the last quiet evening before family arrives, take that one. Our moon phase today tool will confirm where the moon is on any night you check.
Is the Cold Moon 2026 a supermoon?
The Cold Moon 2026 is a supermoon, and the closest full moon of the whole year. NASA's hourly Moon data for 2026 puts it about 356,750 km away at the peak, with perigee following only around seven hours later, and no other full moon in 2026 comes closer. The Old Farmer's Almanac agrees, calling it the closest supermoon of the year and the middle of a run of three (November, December and January).
On NASA's numbers it appears about 14 per cent wider than 2026's smallest full moon, the Blue Moon of 31 May. Next to an ordinary full moon the difference is much smaller, and the Almanac is refreshingly honest that it can be imperceptible to the eye. If you want it to look enormous, catch it rising, when any moon looks bigger against the horizon.
Why is it called the Cold Moon?
It is called the Cold Moon because, for the people who named it, December was when winter really set in. In the Old Farmer's Almanac's words:
"December’s Full Moon is most commonly called the Cold Moon (Mohawk), reflecting the frigid season."Catherine Boeckmann, Executive Digital Editor, The Old Farmer's Almanac
The Almanac also records it as the Long Night Moon (Mohican), because it rises during the longest nights of the northern year, close to the December solstice, and stays above the horizon for a long time.
The Cold Moon used to belong to January
Here is a detail most Cold Moon pages leave out. In the oldest well-known printed list of these names, the explorer Jonathan Carver's 1778 Travels Through the Interior Parts of North-America, December is the Hunting Moon and the Cold Moon is January, because that was when the freeze was hardest. A 19th century fraternal society that adopted Carver's list kept the Cold Moon in January too, according to Wikipedia's history of full moon names.
When almanacs began printing one name per full moon in the 20th century, December went by something else entirely. The 1937 Maine Farmers' Almanac listed its autumn names as:
"Fall Moons: Harvest Moon, Hunter's Moon, Moon before Yule"1937 Maine Farmers' Almanac, as reproduced in Wikipedia: Full moon names
So the December "Cold Moon" you see everywhere now is a name with real 18th century North American roots that has since slid a month along the calendar. That does not make it fake. It makes it what all calendars are: a human system that gets edited.
Other names for December's full moon
December's full moon has more alternative names than most, and nearly all of them are about cold. These are the ones the Old Farmer's Almanac records, with the people it attributes each to:
| Name | Attributed to |
|---|---|
| Long Night Moon | Mohican |
| Moon Before Yule | European tradition, tied to the Yuletide festival |
| Moon of the Popping Trees | Oglala |
| Frost Exploding Trees Moon | Cree |
| Drift Clearing Moon | Cree |
| Hoar Frost Moon | Cree |
| Snow Moon | Haida, Cherokee |
| Winter Maker Moon | Western Abenaki |
| Moon When the Deer Shed Their Antlers | Dakota |
| Little Spirit Moon | Anishinaabe |
You will also see "Oak Moon" around. According to the same Wikipedia history, that one traces to Deanna J. Conway's 1995 book Moon Magick, which offered Cold, Oak or Wolf Moon for the last lunar month of the year without citing sources for most of its names. It is a modern addition, which is fine, as long as nobody tells you it is a thousand years old.
The Cold Moon in Australia: a long night name on the shortest nights
This is where the Cold Moon gets properly strange for us. The traditional names are Northern Hemisphere seasonal labels, and in Australia summer begins on 1 December under the meteorological seasons (seasons explained). The December solstice in 2026 falls at 20:50 UTC on 21 December (solstice dates), which is 7:50 am AEDT on Tuesday 22 December: our longest day. So the "Long Night Moon" arrives two days after the longest day of the Australian year, during the shortest nights we get. You could not design a less accurate name for this hemisphere if you tried.
It also changes how the moon behaves in your sky. A full moon sits opposite the Sun. In the northern winter the Sun is low, so the December full moon rides high and stays up for a long time. In our summer the Sun is high, so the Cold Moon does the reverse: it skims low across the northern sky and spends fewer hours above the horizon. NASA's data has this full moon about 27 degrees north of the celestial equator, which gives roughly these highest points (a rough calculation that ignores refraction):
| City | Highest point above the northern horizon |
|---|---|
| Darwin | About 50 degrees |
| Brisbane | About 35 degrees |
| Perth | About 31 degrees |
| Sydney | About 29 degrees |
| Melbourne | About 25 degrees |
| Hobart | About 20 degrees |
If you are in Hobart, a tall gum tree on the northern side of your yard will hide it entirely. Find a beach or a hill with a clear view north.
It is also worth remembering that this continent has its own, far older ways of reading the seasons. The Bureau of Meteorology hosts a number of Aboriginal and Torres Strait Islander traditional seasonal calendars, handed down from generation to generation. They will tell you more about December where you live than a Mohawk name for a frozen month ever could, however much respect that name deserves in its own place.
Cold Moon meaning: what it is traditionally said to signify
As the last full moon of the calendar year, the Cold Moon is traditionally said to be a moon of reflection and completion: looking back at the year, keeping what worked and letting the rest go. In the north that sits naturally with long dark evenings indoors. In Australia it collides with the office party, the school holidays and the annual negotiation over whose turn it is to host, which is arguably when you need reflection most.
Astrologically, the Sun moves into Capricorn at the solstice, so a full moon two days later falls in Cancer. In astrological tradition Cancer is the sign of home, family, belonging and feelings, and it is the moon's own sign (more on that in our guide to the Cancer moon). It is set against the duty, structure and long-range goals of Capricorn season. A Cancer full moon on Christmas Eve, opposite a Capricorn Sun, is traditionally read as the tension between what you feel you owe your family and what you actually want. That is not a prediction. It is just December. If you want to know how a Cancer full moon interacts with your own chart, start with our moon sign calculator.
A Cold Moon ritual for a hot Christmas
A ritual built for snow does not work at 32 degrees, so this one leans into the actual season. It takes about half an hour and works best on the evening of 23 December, before the house fills up.
- Cool down first. Since nothing about an Australian Cold Moon is cold, make it literal: a cold shower, a swim, or your feet in a bucket of cold water. It is the only part of this ritual that will feel seasonal.
- Review the year in three lines. Write down three things from 2026 worth keeping, and one thing you are not taking into 2027. Be specific. "Stress" is not a thing. "Saying yes to every committee" is.
- Set one family boundary. This is a Cancer full moon opposite a Capricorn Sun, so decide, in advance and in writing, one limit for the next few days: the time you leave, the topic you will not discuss, the dish you will not be making.
- Go and find the moon. Look low in the north after sunset. Spend five minutes with it. Do not photograph it; it never looks as good on a phone.
- Say thank you. Name one person who made your year easier, and tell them before Boxing Day. If you prefer something more formal, our full moon prayer works well here.
If the idea of a longest-night ritual appeals, keep our winter solstice ritual for June, when the long nights are actually ours. For other practices, browse the rituals library.
What the evidence says
The Cold Moon is a name, and the moon is indifferent to it. What is measurable is the astronomy: this full moon really is the closest of 2026, it really does peak on Christmas Eve in Australia, and it really does sit low in our summer sky. The meanings layered on top are tradition, useful as a reason to stop and take stock at the end of the year, but not evidence of anything happening to you. Take the prompt, skip the prophecy.
The Cold Moon in the full moon sequence
The Cold Moon follows November's Beaver Moon, also a supermoon, and comes before January's Wolf Moon, which NASA's tables put at 12:17 UTC on 22 January 2027 (11:17 pm AEDT that Friday) and which the Almanac counts as the third supermoon in the run.

Frequently asked questions
The Cold Moon in 2026 peaks at 01:28 UTC on Thursday 24 December, according to NASA's lunar phase tables. In Australia that is 12:28 pm AEDT in Sydney and Melbourne, 11:28 am AEST in Brisbane and 9:28 am AWST in Perth, all on Christmas Eve. Because the peak is in daylight, watch it rise on the evening of 23 or 24 December.
The Cold Moon 2026 is a supermoon and the closest full moon of the year. NASA's Moon data puts it about 356,750 km from Earth at its peak, with perigee around seven hours later. The Old Farmer's Almanac counts it as the middle of three consecutive supermoons, between November's Beaver Moon and January's Wolf Moon.
It is called the Cold Moon because December brings the frigid weather of the northern winter, and the Old Farmer's Almanac attributes the name to the Mohawk. Interestingly, Jonathan Carver's 1778 list put the Cold Moon in January and called December the Hunting Moon, so the name has shifted a month over time.
The Cold Moon is a full moon: it is the traditional name for the full moon in December, the last full moon of the calendar year. In 2026 the moon is fully illuminated at 01:28 UTC on 24 December, and it looks full to the naked eye for about a night either side of that moment.
Another name for the Cold Moon is the Long Night Moon, attributed to the Mohican, because it rises near the longest nights of the northern year. Others include the Moon Before Yule, Moon of the Popping Trees (Oglala), Hoar Frost Moon (Cree), Winter Maker Moon (Western Abenaki) and Little Spirit Moon (Anishinaabe).
The Cold Moon is traditionally said to mean reflection and completion, a time to look back on the year and decide what to keep. In 2026 it falls in Cancer opposite a Capricorn Sun, which astrological tradition reads as the pull between family and duty. These are traditional associations, not predictions, so use them as a prompt.
The Cold Moon in Australia rises in early summer, two days after the December solstice gives us our longest day, so its Long Night Moon name is the opposite of local reality. It also sits low in the northern sky, at roughly 29 degrees from Sydney. Here it works best as an end-of-year reflection prompt.
