The December cold moon is the last full moon of 2025 – a time of transformation that affects all the signs. Let’s face it, it’s been a big year astrologically. From a particularly intense Mercury Retrograde to October’s eventful full harvest supermoon, it seems like most star signs haven’t managed to catch a break in 2025.
While the name ‘cold moon’ sounds kinda gloomy, it’s really just a reflection of the month and the chilly weather during this time of year. It’ll appear in the UK on December 4, 2025, rising at approximately 14:48 GMT and visible in the night sky throughout the evening.
This ‘supermoon’ will look bigger and brighter than usual as the moon will be closer to the Earth for a period of time. According to NASA, a supermoon is 14% larger and 33% brighter than a micro moon, and occurs when the moon is at its closest point to Earth during a full moon phase.
With that in mind, you might be wondering how this astrological event will affect your star sign in particular. Below, we chat to our in-house astrologer Emma Howarth, who shares her need-to-knows about what the December cold moon has in store.
What the December cold moon means for your star sign
Astrologically, this lunation signifies reflection, stillness, and the transition into a new cycle, emphasising communication, truth, and asking questions as the year ends. Rising in the sign of Gemini, it represents a period of clarity, communication, and intellectual breakthroughs as emotions are illuminated and brought to a head. It encourages you to process information, refine your communication skills, and find a balance between logic and emotion. This is a time to express ideas, share insights, and let go of old thought patterns to make space for new understanding.
“Collectively, it’s a good time to let go of limiting beliefs that might be holding us back and start seeing things from new perspectives,” says Emma. “It’s a good full moon for sharing your voice or story, too.”
