“Wake me up when September ends” … or more likely “Don’t let me sleep through this one,” because Eclipse season is ON!
September 2025 is marked by 2 powerful eclipses: a Total Lunar Eclipse in Pisces, and a Solar Eclipse in Virgo.
Eclipse season is when things ‘happen’ – so get ready for a month full of twists, turns, and interesting developments.
This month, the astrological landscape is in flux: most planets are either in the final degrees or the very first degrees of their signs.
Times are changing, and September feels like that threshold moment – with one foot in the old world and one in the new, we’re invited to take stock of what’s worth carrying forward and what’s better left behind.
But let’s take a look at the most important astrological events of the month:
September 1st, 2025 – Saturn (re)Enters Pisces
Saturn left Pisces to enter Aries back in May 2025.
You thought that the Saturn-in-Pisces story was done and dusted? Not so fast. On September 1st, 2025, Saturn retrograde reenters Pisces for one last stroll through the sign.
Slow-moving planets always have some loose ends to tie up. It ain’t over till it’s over.
So yes, there’s a bit more to the Saturn-in-Pisces story. Most of us don’t like to go back and revisit old territory – we just want to move on with our lives. But there’s gold in the integration process – when we pause to reflect, we gain a new perspective, and only then can the cycle truly complete.
The good news? Later this month, Saturn begins to form a trine to Jupiter in Cancer. Even better, in October and November we’ll see a beautiful Grand Water Trine between Saturn in Pisces, Jupiter in Cancer, and the planets moving through Scorpio.
And this brings a rare opportunity for closure and emotional healing – a wave of support from the universe to help us close one chapter and welcome the next.
September 2nd, 2025 – Mercury Enters Virgo
On September 2nd, 2025, Mercury enters its favorite sign: Virgo. Mercury moves quickly here, spending just 17 days in the sign.
Mercury (Hermes) was the messenger of the gods, the only deity who could travel from the Underworld to Olympus and back, delivering important news wherever it was needed. We have the same spirit of movement and communication whenever Mercury is activated.
Think of it like newspaper delivery kids zipping through the neighborhood on their bikes, tossing the latest updates onto doorsteps – or, in today’s world, like Instagram or TikTok Reels, with fresh content appearing in mobile feeds every second.
That’s Mercury. Mercury is all about swift movement, rapid delivery, and connecting information to where it needs to go.
In Virgo – the sign of both its domicile and exaltation – Mercury’s function is at its absolute peak. Here, Mercury can do what it does best, unhindered: the weather is perfect, there’s no traffic jams, so the messenger can reach every neighborhood on the route.
Mercury will be clearing the Virgo eclipse path, delivering all the information you need – including those last-minute details or missing puzzle pieces – at lightning speed.
The downside? When everything happens fast, there’s barely time to absorb the lessons. On the bright side, whatever has felt stagnant or sluggish in your life will suddenly get a huge burst of momentum.
September 6th, 2025 – Uranus Turns Retrograde
On September 6th, 2025, Uranus – freshly ingressed into Gemini – turns retrograde at 1° of the sign.
This station is a light bulb moment about where we are right now in this new Gemini reality, and where we might have rushed ahead or skipped steps in our eagerness to embrace change.
At the time of the station, Uranus is tightly trining Pluto in Aquarius. There’s a sense of fatedness in the air, a feeling that the forces at work are bigger than us. And it’s the right kind of fatedness – we feel we’re in the right place at the right time.
And even if the path forward isn’t entirely clear, there’s a quiet confidence that the universe is on our side, and that things will eventually work out.
September 7th, 2025 – Total Lunar Eclipse In Pisces
On September 7th, 2025, we have a Full Moon and Total Lunar Eclipse at 15° Pisces. The eclipse is total – which means it’s intense – VERY intense.
If you have planets or angles in the middle of the mutable signs (Gemini, Virgo, Sagittarius, Pisces), you’re going to feel this one big time.
It’s also a North Node Eclipse. Both North and South Node eclipses are connected with our life purpose, but there’s a subtle difference: while South Node eclipses are more about releasing old patterns or karma, North Node eclipses are about creating new possibilities.
This Full Moon Eclipse forms an auspicious trine aspect to Jupiter (at 19° Cancer) – a reminder that we have what it takes – that all the resources we need are within reach. In fact, with Pisces’ magic in the mix, what shows up now might seem a little bit too easy, or too good to be true.
And this is where Mercury (at 10° Virgo), opposing the eclipse, steps in to ask the anticlimactic but necessary question: Are you sure? Have you looked into the details?
This questioning energy is not meant to raise doubt or stop us from moving forward. It’s meant to make sure we do look at the fine print, so we’re fully aware of what this North Node opportunity truly entails.
Because if we don’t read the fine print now, those overlooked details could come back to haunt us later – probably at the next round of Virgo/Pisces axis eclipses.
With eclipses – more than any other transits – what goes around truly comes around. So it’s important that we plant the kind of seeds we actually want to see blooming in our future.
September 13th, 2025 – Mercury Cazimi In Virgo
On September 13th, 2025, Mercury conjuncts the Sun at 20° Virgo. This transit is like the Full Moon – or better said, the “Full Mercury” of the current Mercury cycle – a culmination point, bringing deep insight and clarity.
Remember, Mercury is the messenger of the gods – the “deliverer” of important messages.
The Sun is our life purpose.
So whenever the Sun conjuncts Mercury, we receive a message about who we are and what our purpose is. This message may or may not feel like a dramatic breakthrough (that’s more Uranus).
Yet, that doesn’t make it less important. Mercury conjunct Sun messages are always meaningful.
And if a message keeps repeating – as often happens during Mercury transits – that’s not a reason to dismiss it. On the contrary, its persistence is a sign it matters. It will keep coming back until we finally tune in and listen.
September 18th, 2025 – Mercury Enters Libra
On September 18th, 2025, Mercury enters Libra. After a 17-day sprint through Virgo, Mercury lands in the uncharted territory of the Other.
Here, ideas echo. Opinions are challenged. And in the back-and-forth dance of dialogue and debate, something shifts: we allow the Other in, and in doing so, create something greater than the sum of our individual perspectives.
The result? A broader, more nuanced understanding of ourselves and the world around us.
September 19th, 2025 – Venus Enters Virgo
On September 19th, 2025, Venus leaves Leo and enters Virgo.
The difference between look-at-me Venus in Leo to practical and humble Venus in Virgo is like Barbie vs. Cinderella.
Unlike Barbie, Cinderella was not born in a shiny outfit… she had to scrub the whole house to go to the ball.
But for Cinderella – and for Venus in Virgo – the reward means now more because she actually earned it.
With Venus in Virgo, the slogan changes from “Because I’m worth it” to “Because I’ve earned it.”
September 21st, 2025 – Solar Eclipse In Virgo
On September 21st, 2025, just before the equinox, we have a “Forget me not” Solar Eclipse at 29° Virgo, the very last degree of the sign.
This is a spectacular eclipse that bridges the gap between the “world before” and the “world after” the ‘Genesis’ Saturn-Neptune conjunction at 0° Aries (in February 2026).
The eclipse is opposite Saturn (at 28° Pisces) and Neptune (at 0° Aries), and is trine Uranus (at 1° Gemini) and trine Pluto (at 1° Aquarius).
The Eclipse (the Sun and the Moon) forms the propeller of a kite – the engine, the push, the fuel for the new reality that’s just around the corner.
The geometry of this Eclipse is fascinating: most planets are either at the first or last degrees of their signs (even Mars is at 29° Libra), further highlighting the “a door closes, a new door opens” energy that is the signature of this lunation.
Change can feel unsettling, but the supportive aspects – the grand trine – surrounding this eclipse suggest there’s a higher plan orchestrated by the universe – something that’s guiding us toward something better, and even more aligned with our true purpose.
This is a South Node Eclipse (about releasing the old). It’s at 29 degrees (about closing a chapter). The message couldn’t be clearer. It’s time to integrate the lessons, and just like a Phoenix, allow ourselves to be born again from our own ashes.
This is not about erasing the past, but about using what we’ve built so far as the foundation to step into a better, more fully realized version of our lives.
29° Virgo is not just the last degree of Virgo; it’s also the final degree of the first hemisphere of the zodiac – the part that’s all about “Me” and “My world.” From Aries to Virgo, we’ve grown, developed, and maybe even found mastery in our field.
But focusing on our own growth, living from a “Me” island, can only take us so far. Sometimes we can’t make it on our own. The way forward now asks us to welcome new perspectives, and to step into the hallmark of the second half of the zodiac: life beyond the Self.
September 22nd, 2025 – Sun Enters Libra
On September 22nd, 2025, the Sun enters Libra. Happy bday to all Libras out there and happy equinox to everyone!
The Equinox is that powerful time of the year when the day is equal to the night.
This point of equilibrium is also a turning point → the balance between day and night now shifts. There’s a new season bringing new developments, new opportunities, and new beginnings.
And while Libra is almost synonymous with the word “balance” – and balance sounds a bit like inaction -, let’s not forget that Libra is a cardinal sign. The Libra season is actually a great time to take action – get yourself out there, make connections, and initiate new projects.
September 22nd, 2025 – Mars Enters Scorpio
On the same day Sun leaves Virgo to enter Libra, Mars leaves Libra to enter the sign of its domicile, Scorpio.
Mars feels great in Scorpio because in this fixed, powerful sign, it can channel its intense energy and passion with surgical precision. ‘Surgical’ quite literally: both Scorpio’s glyph and Mars’ glyph feature an arrow – a symbol of assertive, directed energy that needs an outlet for expression.
Mars in Scorpio is the most resilient, strong-willed, and passionate Mars placement.
Nothing will stop Mars in Scorpio from getting what he wants. Setbacks? Challenges to overcome, not reasons to quit.
So if there’s been something in your life you didn’t feel ready – emotionally or energetically – to face or pursue, Mars’ transit through Scorpio is your invitation to go all in.
This is the time to commit fully, confront your fears, and draw on your inner reserves of courage and determination to do what you know you need to do.
