December begins in Montreal with a flurry of snow, a little freezing rain (ouch) and a big blue sky. We’re entering the twelfth month of the year, but we’re already in the last lunar cycle of 2025, and on December 4, the moon will be full.
We’ve already read – or listened to on TikTok – the astrology for December 2025: Venus is in Sagittarius, Pisces will be lucky, Taurus will be passionate. As we slowly begin to think about starting our vison boards for 2026, we recommend stopping everything for this full moon, sticking your head out the window and looking outside.
Not only does the December full moon bring the arrival of winter, cosmically speaking, but it’s a supermoon this year – and it’s going to rise at just the right time.
Cold Moon
The Cold Moon is the name given to the December full moon in the English, American and Canadian Gregorian calendars. According to the Farmer’s Almanac, it’s a name that brings together and reflects the native, colonial and European semiotics of North America.
The name we give it today, “Cold Moon”, is derived from the Mohawk language. Obviously, it’s for the onset of frost and winter.
Among the other aboriginal nations of North America, this full moon is called;
- Drift Clearing Moon (Cree)
- Frost Exploding Trees Moon (Cree)
- Moon of the Popping Trees (Oglala)
- 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)
Supermoon
The Cold Moon will also be a “supermoon” in 2025. That means it’s going to be really gigantic, and also appear more orange than usual.
As well as being a photo opportunity, it’s an astronomical phenomenon called “perigee”. When the Moon, which revolves around the Earth in an oval orbit, is closest to our planet, it appears brighter and much larger.
For all those protesting, this can also be an excellent omen…
Practical info
The Cold Supermoon will rise directly after sunset on December 4, 2025, reaching its peak at 6:14 pm ET.
Enjoy watching the December full moon!
