September 2025 Astrology Transits

The astrology of September...

September arrives on the waves of change: two eclipses, Saturn shifting signs, and Mars diving deep into the sign of secrecy and transformation; Scorpio. This is a month where we’re asked to shift, release, and recalibrate to find more alignment with our deeper truths. The cosmos are active with retrogrades and exact aspects that weave together themes of endings, beginnings, and karmic changes. Let’s take a look at the major transits:

September 1: Saturn retrogrades back into Pisces

Saturn steps back into Pisces to begin the month, softening the fiery edge it has expressed in Aries over the last few months. This return to Pisces is a sign of unfinished business: Are there dreams, boundaries, or spiritual lessons that still need your attention?. The next few months will be a time to revisit how structure and discipline support your intuition, not suppress it.

September 2: Mercury enters Virgo

Mercury, in one of its home signs, will help sharpen our focus and bring more clarity to our thoughts and communication. After the fogginess of the recent retrograde, details will finally begin to click and plans will come together more easily. Conversations may feel more grounded and practical during this transit.

September 6: Uranus stations retrograde in Gemini (01°27’)

Uranus reversing in early Gemini yet again activates a web of supportive aspects that have been following us for some time: trine Pluto retrograde in Aquarius and sextile Saturn retrograde in Pisces + Neptune retrograde in Aries. This marks a collective check-in on how fast change is unfolding in technology, communication, and community structures. Expect inner breakthroughs that may not show outwardly until Uranus goes direct.

September 7: Full Moon Lunar Eclipse in Pisces (15°22’)

This is a deeply emotional and karmic eclipse – a culmination of cycles linked to surrender, compassion, and your spiritual path. Eclipses accelerate change, and this one may dissolve old illusions, clearing space for deeper faith and flow. Remember, doing any sort of ritual during an eclipse may feel more intense, so use caution and be discerning!

September 13: Sun conjunct Mercury in Virgo (20°54’)

Illumination meets insight when these two planets align. With supportive trines to Jupiter in Cancer and a fading conjunction to the Nodes, this cazimi can bring major downloads that tie personal choices to bigger karmic stories. Pay attention to what’s being revealed around work, service, or health – it could be planting seeds for long-term growth.

September 18: Mercury enters Libra (opposed Neptune Rx in Aries)

Words seek balance and fairness when Mercury enters Libra, though Neptune’s opposition may blur what’s reality (think: wearing rose-colored glasses). Diplomacy and charm flow easily, but clarity requires discernment and patience on your part. Think carefully and ask lots of questions before making any long-term commitments.

September 19: Venus enters Virgo (square Uranus in Gemini)

Relationships and values are getting a shake-up today. Venus in Virgo asks us to get practical and intentional about love and money, but Uranus’ square to begin this cycle may bring surprising twists. Flexibility is key during this time.

September 21: New Moon Solar Eclipse in Virgo (29°04’, opposed Saturn Rx in Aries)

This powerful eclipse is aligning with Saturn to close out eclipse season… one word: INTENSE. This lunation closes one chapter while demanding new commitments in the next. Where are you ready to align habits and structures with what truly matters? Big choices may feel fated, especially around health, service, or the daily systems and routines you rely on.

September 22: Mars enters Scorpio (square Pluto in Aquarius) and Sun enters Libra (opposed Neptune Rx in Aries)

Mars, feeling at home in Scorpio, will turn the intensity up to 100 during this transit. Beginning with a square to Pluto into the sign that rules Pluto, power dynamics will come to the forefront. This can manifest as deep determination, but also conflict or obsession if you’re not careful. Be wary of unnecessary conflict or power struggles, especially today as the energy will be at its most potent.

On the same day, Libra season begins with a haze! Neptune’s opposition makes the Fall Equinox feel both idealistic, yet uncertain. Seek balance, but don’t lose yourself in fantasy. Themes of justice, relationships, and harmony will be at the forefront as the season shifts.

Overall, September 2025 is not a light month – it’s an eclipse portal, a Saturnian shift, and a dance of retrogrades that remind us growth comes with both endings AND beginnings. The invitations this month are to surrender what’s out of your control, lean into your spiritual practices, and commit to the structures that support your higher path.
