December 2025’s most powerful transits: Stars, retrogrades, and Moon magic

As 2025 draws to a close, the universe invites us to pause, reflect, and prepare for fresh beginnings. December’s planetary movements offer a chance to honor the lessons of the year, release what no longer serves you, and set intentions for 2026.

With Sun, Moon, and retrograde energies guiding the way, it’s a month for clarity, emotional insight, and turning inspiration into action.

Sagittarius Sun

The month begins under the expansive, adventurous energy of the Sun in Sagittarius. For the first three weeks, optimism and curiosity are in the air. Sagittarius encourages exploration.

With Jupiter in Gemini amplifying curiosity, it’s the perfect time to think big, share your goals, and let your imagination roam.

This is a season to reconnect with your vision for the future. Sagittarius reminds us to trust our instincts, embrace courage, and believe in possibilities.

Capricorn Sun

As the Sun enters Capricorn and the Winter Solstice approaches, the cosmic focus shifts from aspiration to action. Capricorn’s energy encourages grounding, responsibility, and structure. Now is the moment to turn big ideas into practical goals.

Where Sagittarius asks, “What could be?” Capricorn asks, “How can this happen?” By enabling vision with discipline, December provides the tools to set realistic plans for 2026.

Mercury Retrograde

Mercury retrogrades in Sagittarius and Capricorn through the month. While often linked to delays or miscommunications, this retrograde is better understood as a valuable pause. It’s a chance to slow down, reflect on past choices, and realign with what truly matters.

During this period, revisiting old plans or relationships can bring clarity. Nostalgia may surface, but it’s a guide, helping you reconnect with your purpose.

Avoid rushing major decisions and focus on journaling, heartfelt conversations, or revisiting creative projects left unfinished. Mercury retrograde offers a mental reset, clearing space for a fresh start in the new year.

Full Moon in Cancer

December’s Full Moon in Cancer brings an emotional time. It highlights our need for comfort, connection, and introspection. It’s a time to honor the feelings that have surfaced throughout the year and release outdate beliefs that do not serve you.
