The December 2026 Supermoon—known as the Cold Moon—arrives on December 23, 2026, creating one of the most emotionally powerful full moons of the year. When the moon reaches its closest point to Earth while fully illuminated, its gravitational and energetic influence intensifies dramatically.
What Is a Supermoon?
A supermoon occurs when the full moon coincides with lunar perigee—the point in the moon’s orbit when it’s closest to Earth—making it appear up to 14% larger and 30% brighter than an average full moon.
The term “supermoon” was coined by astrologer Richard Nolle in 1979, and these events occur roughly 3–4 times per year. Research by scientists at the University of Washington found that tidal forces increase by approximately 18% during supermoons. In astrology, the moon’s proximity amplifies its influence on emotions, intuition, and the subconscious mind.

Why the Cold Moon in Cancer Is Exceptionally Powerful
The December 2026 Supermoon gains extraordinary potency because it occurs in Cancer—the zodiac sign ruled by the Moon itself. According to astrological researcher Dr. Bernadette Brady, “When the Moon is in its home sign during a supermoon, we experience a double amplification of lunar energy.”
This cosmic alignment creates what astrologers call a “dignified supermoon,” historically associated with:
- Heightened emotional awareness across all zodiac signs
- Intensified family connections and ancestral themes
- Powerful opportunities for emotional healing and release
- Enhanced intuitive abilities and psychic sensitivity
As acclaimed astrologer Susan Miller notes, “The Cancer Full Moon always brings our attention home—to our families, our emotional foundations, and the nurturing we both give and receive.”
The Spiritual Meaning of the Cold Moon
The Cold Moon earned its name from Native American and Colonial American traditions, marking the arrival of winter’s harshest temperatures. Spiritually, this timing carries profound symbolism:
Themes of the Cold Moon:
- Turning inward for reflection and restoration
- Finding warmth in community and family bonds
- Releasing what no longer serves you before the new year
- Embracing stillness and patience
The Cold Moon serves as a cosmic invitation to honor rest, seek emotional closure, and prepare your spirit for the rebirth that follows the winter solstice.
