December 2025 Astrology Forecast: Planets, Moon Phases, and Other Important Influences for the Month
December arrives with a surge of forward-moving momentum that we need. We enter the month with Mercury just going direct in Scorpio, slowly clearing its post-retrograde shadow and helping us untangle lingering emotional clutter and unfinished conversations. Plus, Saturn has also just recently gone direct in Pisces, which lifts a months-long fog and is giving us a clearer sense of boundaries, priorities, and what truly is going to support our long-term growth. On top of all that? Venus enters Sagittarius bringing a fresh, adventurous, and heart-opening quality to how we love, connect, and express our desires.
It’s also Sagittarius season until December 21, when the Sun moves on to Capricorn, and this is a time of expansion, renewal, optimism, and vision. This is going to help us ground that inspiration into something real. December is always a month of transition, but this year, the currents feel especially strong, so expect a lot of clarity to return, movement to happen, as well as a renewed sense of purpose all around. Let’s dive into the planets, moon phases, and other important influences that are going to shape the month ahead!
December Astrological Forecast
This month is going to bring a mix of intuitive breakthroughs, grounded motivation, and soul-level realignment. Mercury’s movements are especially influential, shifting the tone from deep emotional processing to adventurous thinking. Then, there will be the eventual Capricorn energy that will build steadily, culminating in an end-of-the-year push to commit, build, and stabilize.
Planetary Influences
Neptune Direct in Pisces — December 10
The first major planetary influence in December is when Neptune finally stations direct in its home sign of Pisces. This is going to lift the veil of what has been hanging over our intuition since its retrograde period began. With this, you can expect some emotional clarity to emerge gradually, like a fog dissipating, as well as have some creative inspiration intensify, and spiritual insight will become more accessible. This can also be seen as a recalibration of trust; trust yourself, your vision, and your inner knowing.
Mercury in Sagittarius — December 11
Mercury’s shift from Scorpio’s depth into Sagittarius’s wide–open skies will see communication get bolder, brighter, and more future-focused on December 11. You can expect some big ideas, spontaneous plans, and even philosophical conversations that can help you zoom out. After a retrograde period that really dug into the emotional truths, this is your permission slip to think big again!
Mars in Capricorn — December 15
Mars seems to love being in Capricorn because it’s disciplined, driven, and powerful here, and you can expect motivation to return with some serious force. This transit is going to bring focus, long-term ambition, and the stamina to follow through with all of it! So, if you have projects, decisions, or goals that you’ve been waiting to tackle, mid-month is the time to get them done.
Sun in Capricorn — December 21
The Winter Solstice marks the shift from Sagittarius’s fiery optimism to Capricorn’s grounded determination, and this is also where vision turns tangible! You’re likely to feel more serious, intentional, and ready to build something that can really last. With this energy, you’re going to be encouraged to focus on structure, planning, and have some steady progress as we get ready to close out the year.
Venus in Capricorn — December 24
When Venus moves into Capricorn toward the end of December, love, relationships, finances, and values get a dose of practicality and commitment. This transit puts a focus on loyalty, integrity, and long-term foundations, so it’s not going to be about grand gestures, but instead, it’s going to be about consistency and choosing what and who stands the test of time. This is sort of the perfect energy to help us close out the year with clarity around your heart!
Moon Phases
Gemini Full Moon – December 4
Under the Gemini Full Moon, which is also a Supermoon, communication, information, and truth are in the spotlight across the zodiac! With this energy, you can expect some revelations, conversations you’ve been avoiding, or a moment of clarity around how you express yourself. This can be a great time to release the mental clutter and to remind yourself that your voice matters!
Sagittarius New Moon – December 19
The Sagittarius New Moon asks us to dream bigger! It’s a powerful moment for setting intentions around growth, expansion, travel, education, confidence, and bold new life chapters. With Mercury also in Sagittarius at this time, the energy feels aligned for visionary thinking and fresh, amazing beginnings.
Other Important Influences
Sun Squares the Lunar Nodes — December 5
This aspect is going to be quite the cosmic checkpoint. It’s going to highlight choices, life direction, and whether you’re moving toward growth or staying stuck in your old patterns. With this energy, you can expect a nudge from the universe telling you to adjust your path, and it might not always be a subtle message.
Mercury Conjunct Lilith — December 11
This transit is going to amplify some raw honesty, authentic expression, and the parts of your voice you’re usually a bit hesitant to reveal. Truth-telling takes on a special edge, and conversations might feel electric, liberating, or slightly rebellious around this time, and it’s likely it’s going to be exactly what you need at the right moment.
Lilith Enters Sagittarius — December 20
When Lilith enters Sagittarius on December 20, its wild, feminine energy is going to create an interesting clash with Sagittarius’s truth-seeking fire. This is likely to bring a collective desire for more freedom, autonomy, as well as some bold, unapologetic self-expression, so expect that some courage is going to rise up in areas of your life where you’ve felt held back.
Jupiter Square Chiron — December 21
This transit is like a healing moment wrapped inside a great opportunity for growth. It might bring up some old wounds around confidence, self-worth, and independence, but the reason for this is so that you can work on rising above all of that! Jupiter likes to expand, and Chiron is about healing, so together, they push you towards a deeper sense of wholeness.
Juno Enters Capricorn — December 29
When Juno enters Capricorn on December 29, partnership dynamics are going to get serious, grounded, and more intentional. There is a strong value on loyalty, long-term systems, and commitments that are built to last under this energy, and as the year winds down, relationships might shift into some deeper clarity.
Final Thoughts
December has always been considered something of a bridge; a transition from the expansive fire of Sagittarius to the steady, ambitious earth energy of Capricorn. With so many planets shifting signs and many other influences, this month is going to help clear out the fog, reclaim your momentum, and choose your direction with purpose. This is a powerful time to align with what is real, what’s inspiring, and what’s meant to grow with you into the new year! Remember that you’re not just getting ready to close a chapter when we enter the twelfth month, you’re preparing to build something meaningful, so let December guide you toward clarity, stability, and the kind of hope that is deeply rooted in truth!
