Full Cold Supermoon in Gemini
A Thousand Grasses (Chigusa) (1900) by Kamisaka Sekka
Well, we made it. This year has been both fast and slow, and maybe that is just because I am inching past middle age and entering my Baby Crone years, but the energy has been a bit whiplashy for the last twelve to forty-eight months or more. We are in the final stretch of 2025, and on Thursday, December 4th, we welcome the Cold Supermoon in Gemini. Gemini is the Messenger of the Zodiac, ruled by Mercury, and as many of us are already aware, Mercury has recently gone direct, clearing the fog a little but also bringing with it the usual retrograde aftershocks for a few days or short weeks while we adjust. The good news is that we are entering this Full Moon with Mercury steadying itself again, which makes this moment one of growing clarity and coherence.
2025, the Year of the Snake and also the number nine in numerology, has been a year of shedding, endings, and revelations that pushed many of us into deeper, more genuine versions of ourselves. The world we stand in today is not the one we stepped into back in January. The outer landscape has shifted, but so has the inner one, and that Gemini duality is here to illuminate. Next year feels wide open, a landscape of possibility mixed with the unknown, and this last Supermoon arrives at exactly the right moment to help us understand what this year has been preparing us for.
Some astrologers are saying this is a gentle Full Moon, while others are already preparing people for something more inflammatory. So which one is it? Well, I’m an intuitive astrologer, and I think it depends entirely on where you’re standing at the end of this year. Did you do the inner work, or did you avoid or bypass the hard stuff? Your answer to that question will offer some insight into how this Moon is likely to feel for you. If you’re experiencing it as intense or heavy, it may be because there are things you’ve avoided, forgotten, or tucked away for another day. We all do that, so there is no shame in it. Sometimes the work hides in our blind spots, and other times we’re too exhausted to deal with something that needs attention, and that is completely human. If you’re feeling some discomfort come up with this Full Moon, if you’re receptive, you can take some deep breaths and ask the Gemini Full Moon to shine a soft light on any lingering issues or loose ends.
This could feel like inflammation on a physical, emotional, spiritual, or mental level, but that doesn’t mean the Moon is literally causing physical inflammation. The Sun is conjunct Antares, a fixed star that has a Mars-like heat to it, which can stir reactivity or sudden clarity in places where we may have been avoiding being honest with ourselves or others. Mercury is also adjusting to its direct motion, which can make some people feel mentally or emotionally irritated as things begin to reorganize. Plus, it’s getting cold and we’re at greater risk of getting run down and sick this time of year thanks to lack of sunlight, exercise, and holiday food indulgence. I’m not here to shame; I’m in the trenches with most of you, and I find myself wanting to hibernate with the cats as much as possible, barely able to keep my eyes open an hour after the Sun goes down just a few hours past noon, but you get what I’m saying. It’s the kind of flare-up that shows you where truth wants your attention, not necessarily something happening inside your physical body. Whether you feel that heat as discomfort or as insight depends on how ready you are to face what comes up and how well you’re taking care of yourself.
This is what I love about the rhythm of the Full Moons and New Moons. They offer a built-in ritual for taking inventory of our lives. They remind us to pause long enough to reflect on what’s shifting. They give us structure and timing, and they let the zodiac, the archetypes, and the Seasons guide our awareness. Each astrological event focuses on certain themes, and within that illumination we find both tension and comfort. These cycles help us notice what wants our attention and what we’re ready to release, and they give us language for the parts of our lives that are still finding their shape.
We are now in Sagittarius season, which means the Sun is in its most adventure-seeking and truth-loving phase of the year. This doesn’t necessarily mean that you’ll want to go on some quest or climb a mountain. It might, but you may find your curiosity being stirred within, wanting to learn, to understand, to discover something new. And as you know, Sagittarius and Gemini are signs that exist in opposition to one another. Full Moons always highlight the tension between two opposite signs, and the Gemini Moon meeting the Sagittarius Sun creates one of the most thought-provoking polarities in the Zodiac, which I think is a fitting way to end a year that has been filled with reflection and also excitement and forward momentum for all the amazing possibilities that lie ahead. Sagittarius looks to the horizon and searches for purpose and meaning, while Gemini examines the details that give us clarity, understanding, and appreciation. Sagittarius asks the bigger questions, and Gemini helps us find the best way to ask and answer. Together, they form a beautiful tension that helps us end the year with a fuller understanding of where we’ve been and where we might be going next.
The Gemini Full Moon becomes a kind of translator for all the transformation we’ve experienced throughout 2025, and that includes the good and the difficult. Nothing is perfect or ideal, no such creature exists, but we can always look for gratitude and stay open and flexible enough to learn from every lesson life throws our way. Gemini helps us uncover the message beneath the mayhem and the mundane. It helps us articulate the internal changes that were hard to identify while we were in the middle of living through them. Gemini lives comfortably at the crossroads of duality and invites us to recognize our own contradictions without judgment or shame. It holds both sides of the story at once, and from that perspective, we can gain clarity about a lot, including what we’ve released and why. Gemini also carries its Trickster side, the part of the archetype that reveals what we may have overlooked or misunderstood. Sometimes it’s playful, but there is always a purpose if you’re willing to pause and look honestly from all sides. It doesn’t play tricks to confuse us but rather to illuminate the hidden mechanics of our choices and patterns. Sometimes the truth arrives quietly and we miss it the first time, and other times it hits us like a sock filled with quarters to the face. Either way, there is something to be learned if we’re willing to take personal inventory and take responsibility and accountability for our lives. Life happens with us, not to us, and we need to learn that we are the architects of our own existence. We may not be able to control outside events, but we can control our interpretation and reactions, and that is powerful magic.
This Cold Gemini Supermoon shines a bright and steady light on the shifts we’ve been navigating and reminds us of how far we have traveled, both internally and externally. It gives us the chance to return to the questions we avoided because we were too overwhelmed, too exhausted, or simply not ready. Now we may find that the answers come with surprising honesty or arrive as unexpected truths. This moment is a pause in the movement of the year, a chance to take stock, to breathe, and to recognize the things in our lives we are ready to release as 2025 comes to a close. I sometimes find myself sarcastically singing “Let it go” when there are things I’m clutching so tightly that my hands might as well bleed. It’s a reminder that some things are meant to be carried, and others have an expiration date. What have you been holding on to that you’re finally ready to let go of before stepping into the New Year?
This is not a heavy or shadowed Full Moon. It’s not the kind of Moon that drags you through the emotional underworld. If anything, it feels like a gentle unraveling, an invitation to understand something you’ve been carrying, perhaps all year, in a way that finally makes sense. Gemini is the sign that translates feelings into language. It takes the internal world and gives it shape through thought, speech, and story. Under this Full Moon we are offered the ability to articulate what has been blurry, confusing, or unprocessed. It’s as though the emotional weight of 2025 becomes easier to name, and because it’s easier to name, it becomes easier to release. We just need to be willing participants in our own lives.
There is always a sense of endings at a Full Moon, but this one holds a specific tone because the Moon sits at 13 degrees Gemini, directly opposite the Sun at 13 degrees Sagittarius, and as you already know, is the last Full Moon of the year. And spoiler alert, the final New Moon takes place on the Solstice! But let’s not get ahead of ourselves. This is about the final Full Moon, and part of what shapes this Full Moon in a unique way is not only the Gemini and Sagittarius axis of communication and meaning, but the fact that the Sun is conjunct the fixed star Antares at roughly 9 degrees Sagittarius. Antares is not metaphorical, like the inflammation mentioned earlier. It’s a real astronomical star, a red supergiant that forms the heart of the Scorpion in the constellation Scorpius, and no, this isn’t the same as Scorpio. I kind of wish they picked another animal to avoid confusion, but it is what it is. Because of the way Western astrology measures zodiac degrees, Antares now sits in the tropical sign of Sagittarius. The Full Moon light is therefore reflecting solar energy that is colored by the influence of Antares.
So, if you’re like me, you’re wondering what the hell is Antares. Well, I’ll do my best to tell you as far as I understand it. Antares has been tracked by astrologers for thousands of years across many cultures; its symbolism is remarkably consistent across centuries, from what I could tell. Antares brings clarity, intensity, conviction, and the courage to confront truth. It cuts through noise and refuses to let us look away from what is authentic. It’s not mystical or otherworldly in the way modern language sometimes frames fixed stars. Antares is direct, sharp-edged, and honest. It literally translates to the Rival of Ares, the Greek god of war, whose Roman name was, you guessed it, Mars. Like Mars, it’s a bright red point of light in the sky, and it sits in the heart of Scorpius, which while roughly 550 light years away, is still in our Milky Way galaxy. This bright red supergiant is something ancient people could see in the night sky without light pollution, so it’s no wonder they often compared it to Mars, another red body in space from Earth’s point of view. When the Sun aligns with Antares, in this case both within a few degrees in Sagittarius, we meet a moment when we can see ourselves, our choices, and our motivations with unusual clarity.
Because the Moon is opposing this Sun and Antares conjunction, the emotional awareness that comes up during this Full Moon carries a similar honesty. We become more aware of the gap between what we say and what we truly believe or embody, or between the story we’ve told ourselves and the deeper meaning beneath it. It helps us notice where our thinking has drifted from our truth, or where old narratives no longer align with who we’ve become. This is a Full Moon that highlights contradictions, not to shame us, but to integrate us, and I believe, provide us the opportunity for graceful humility and appreciation for how much we’ve grown and evolved.
Adding to this atmosphere of clarity and reflection is Mercury, the ruler of Gemini, which has only recently stationed direct. Mercury moving forward again brings a stabilizing influence to conversations and inner dialogue. Communication begins to clear, but it remains tender and slow, the way your voice sounds in the morning or if you’ve been quiet for a spell. Misunderstandings untangle themselves quietly. Thoughts reorganize and recalibrate to the new reality we’ve created. Information that was obscured, incomplete, or delayed during the retrograde period now surfaces with clarity. Through this, we have access to a fuller perspective that is not rushed or forced, simply clearer. If you’ve made reading my essays a drinking game, I think the theme of this one can be summed up in one word: Clarity. Now take a swig.
Viewed as astrological complements, these placements create a Full Moon that helps you make sense of your own year. Gemini gathers the pieces; Sagittarius interprets them. Antares demands truth, and Mercury supports expression. This is the kind of Moon that allows the mind to settle around a central realization. You may find yourself finally understanding something that felt opaque, like “Oh… this is what it meant. I see it now!” The understanding doesn’t come through some sort of existential emotional upheaval, but through thoughtful language, expansive perspective, and gentle acceptance and gratitude.
Because this is the last Full Moon of 2025, it naturally invites reflection. However, it’s important to remember that the astrological year does not end until the Spring Equinox, with the end of Pisces and the beginning of Aries Season. We’re not at the threshold of a new cycle just yet. We are simply at a point of comprehension within the one we’re living that just so happens to coincide with the darkest, coldest time of the year and naturally invites that sort of inward reflection. This Full Moon is not asking you to tie everything up neatly. It’s asking you to acknowledge what is complete, to recognize the stories that no longer feel true, to release the mental loops you’ve outgrown, and to let your own clarity become the closure.
You may feel more talkative or expressive than usual, more apt to process out loud, share insights, or reconnect with someone or something you drifted from during Mercury retrograde. It could be a friend, a job, a hobby, anything you had to distance yourself from to survive the recent chaos or confusion, whatever that looked like for you. You may also feel drawn to write, to journal, or to find words for something that has been sitting quietly at the edge of your awareness. Gemini encourages you to use your voice and open the mind, while Sagittarius expands the view and invites exploration and curiosity. Together they help you reshape the year into a narrative that feels accurate and grounded.
If 2025 has been a year of shedding or endings, and many people have felt this, it is this Full Moon that helps you understand what those endings were for. Its purpose is clarity, not closure. Honesty, not judgment. Meaning, not analysis. Let the insights come. Let the year explain itself to you in its own rhythm. Let the words come naturally, without pressure. And if an old story rises to the surface, ready to be released, trust that the timing is right. Above all, allow this Moon to help you tell the truth to yourself. That is the gift of Gemini. That is the precision of Antares. And that is the quiet and reflective power of ending the year with a Supermoon. A reminder that illumination doesn’t always arrive through intensity. Sometimes it arrives through understanding.
