December's full moon is traditionally called the Cold Moon, a name given by Indigenous American tribes. It signifies the long, cold nights and deep winter chill that settle across the Northern Hemisphere at this time of year. This moon usually marks the final full moon of the calendar year, symbolizing a season of rest, reflection, and preparation for renewal.
Spiritually, the Cold Moon represents dedication, stillness, strength, and reflection. It is a time to slow down, prepare for new beginnings in the coming year, and find peace amidst winter's quiet. The moon's rise often coincides closely with the Winter Solstice, a moment when winter truly settles in. The moon in 2025 rises in the astrological sign of Gemini, which brings themes of community, communication, and mental clarity, perfectly suited for the holiday season and setting intentions for the new year.
Astronomically, the December Cold Moon is unique because it rises earlier than any other full moon in the Northern Hemisphere and appears highest in the sky. This is due to the sun's position during the approaching Winter Solstice when the sun is lowest, and the full moon, visible opposite the sun, reaches its highest elevation. This makes the Cold Moon appear very high above the horizon at night.
"The Cold Moon is the December full moon, a moment when the Moon appears completely illuminated by the Sun. Many cultures saw this particular full moon as a symbolic marker that winter had settled in. Nights grew long enough to feel endless. And that shift demanded a name that captured the mood of the season."
The Cold Moon invites people to reflect on the year past, tie up loose ends, and reconnect with others. Its energy encourages releasing old stories and focusing on renewal. Traditionally, it heralds the start of deep winter, urging a dedication to personal goals, peace, and prosperity.
This Cold Moon blends natural and spiritual symbolism, marking the transition into winter with both a celestial spectacle and a reminder for introspection and new beginnings.
