Planetary Events: September 2025

September brings a mix of cosmic movement that’s worth keeping an eye on—especially if you’re feeling stuck, stirred, or strangely nostalgic. Mercury wraps up its retrograde, Venus finally moves forward, and the outer planets continue their slow, mythic churn beneath the surface.

This month’s transits highlight reflection, recalibration, and emotional clarity. Whether you follow astrology closely or just like knowing what’s stirring in the background, September’s sky offers plenty to explore.

Here’s what’s happening—and how it might ripple through your days.

The Autumn Equinox

The wheel turns. On September 22 at 1:19 PM CDT, the Sun crosses the celestial equator, marking the autumnal equinox—the official start of fall in the Northern Hemisphere. Day and night stand in near-perfect balance, just for a moment, before the darkness begins its slow, sacred climb toward winter.

This is also the time of Mabon, the pagan celebration of the second harvest. A moment to gather what’s been grown, honor what’s been lost, and prepare for the descent into shadow. It’s a ritual of gratitude and release, of hearth magic and whispered prayers to the waning light. (Full Mabon blog post coming soon)

This month’s planetary shifts echo that theme: balance, transition, and the quiet unraveling of what no longer fits. Mercury finishes its retrograde, Venus moves forward, and the outer planets continue their deep, mythic churn. It’s a time for reflection, ritual, and recalibration.

Retrogrades

September is thick with retrograde energy—six planets appear to backspin across the sky, inviting reflection, revision, and reckoning. These aren’t celestial mishaps; they’re sacred pauses. A cosmic rewind.

Many planets are continuing their retrogrades through the month but only one is starting their retrograde and that is Uranus.

Uranus Retrograde: September 6th, 2025- February 3rd, 2026

Starts: 1 degree Gemini

Enters Taurus: November 7th, 2025

Ends: 27 degrees Taurus

Signs most affected: Taurus, Gemini, Aquarius

Uranus—the cosmic wild card, the awakener, the rebel—slows its roll in retrograde. Change doesn’t stop, but it stutters. And for those of us itching to leap forward, this pause can feel like static in the soul. Uranus begins its retrograde in Gemini, the sign of ideas, communication, and curiosity. Our visions for the future may stall. Plans unravel. The blueprint blurs. But this isn’t failure—it’s recalibration. We’re meant to gather, question, and refine. The revolution needs a strategy.

Then Uranus slips back into Taurus, where it’s been shaking the foundations of our values, resources, and sense of stability. This final revisit is no gentle farewell. From November 7th to December 2nd, Uranus becomes anaretic in Taurus—sitting at the last, most karmic degree. Expect seismic shifts. Last-minute revelations. A reckoning with what we truly value, and what must be released.

And remember: 2026 begins with Uranus still retrograde in Taurus until January 30th. The year opens with echoes of the past and whispers of the future. We’re not just watching change—we’re becoming it.

Moon Phases

September 14th: Last Quarter

September 21st: New Moon

Eclipse

On September 7–8, the Moon enters Earth’s shadow for 82 minutes of totality—the last total lunar eclipse of the year. Visible across Asia, Australia, Africa, and Europe, it turns deep red as sunlight bends through Earth’s atmosphere. (Apologies for my fellow Western Hemisphere readers, we won't be able to see this one.)

Eclipses mark endings, revelations, and shifts in shadow. This one arrives just before the equinox, stirring themes of release and reckoning.

A deeper dive into the eclipse’s ritual power and emotional resonance is coming soon—watch for a special post exploring its mythic layers.

As August exhales, the Moon prepares to slip into shadow. On September 7, the lunar eclipse arrives—not to startle, but to soften. It’s a quiet reckoning, a dimming of the known, a call to release what’s been clinging to the edges.

This is the clearing before Mabon. The shadow work before the harvest. The sacred stillness before the wheel rights itself.

Let the eclipse draw out what’s hidden. Let the Equinox restore your rhythm. And let Mabon gather your griefs and gratitude's into one golden offering.

The sky is setting the altar. Bring what you’re ready to lay down. And stay for what’s ready to rise. As the Moon slips into shadow on September 7, and the wheel turns toward Mabon’s golden hush, I invite you to join me in a moment of ritual:

What are you releasing beneath this eclipse?

What are you harvesting as the Equinox approaches?

What griefs or gratitude's are ripening in your heart?

Share your reflections in the comments or whisper them into the wind. Tag me if you’re crafting your own ritual—I’d love to witness it.
