Astrology girlies, watch out, because it’s about to be that dreaded time of year yet again with the approach of Mercury in retrograde.
It’s the third and final retrograde of the year for the closest planet to the sun, which many associate with pure chaos.
We recommend approaching the season with caution, rather than worry, and to learn as much as you can to make the best possible decisions before this time. For the full scoop on fall 2026’s Mercury in retrograde, just keep reading.
What Actually Happens When Mercury Is in Retrograde
We’ll be the first to admit that Mercury in retrograde is not at all a scientific phenomenon. It occurs when Mercury’s motion in the night sky appears to reverse from our perspective as observers on earth. In astronomical reality, it’s an optical illusion, and the planet is continuing its usual orbit.
According to astrology, Mercury governs all things related to communication and understanding. Thus, when Mercury is in retrograde, miscommunications and misunderstandings abound. Technology fails, travel plans fall apart and no one seems to be on the same page.
But it’s not all doom and gloom. First, remember that anything related to astrology is meant to be taken with a grain of salt. Secondly, even if it’s the real deal, think of it as a vibe shift, rather than a curse.

When Is Mercury in Retrograde This Fall?
The third and final Mercury retrograde period of 2026 arrives this fall from Oct. 24 to Nov. 13, but it’s possible you’ve already been feeling its chaotic effects. That’s because Mercury retrograde also has a shadow period that begins before and lingers after the event in which its impacts can be felt to a lesser degree. The pre-shadow began on Oct. 4, while the post-shadow will extend until Nov. 30.
Mercury turns direct on Nov. 13. For every retrograde through 2027, see Mercury Retrograde 2026 and 2027: Dates, Signs and Shadow Periods.
After the shadow period ends in late November, expect things to stabilize a bit. You might feel your momentum and clarity returning, making you feel more ready to make strong decisions and move forward. Just make it past Nov. 30 and you’ll be in a good position to head into December with a clear head.

What’s Likely to Go Wrong (And How to Deal)
Mercury retrograde tends to see all things pertaining to communication gone wrong, which can impact more areas of your life than you first expect. Chaos is likely to arise, so be careful with all things related to conversations, technology and travel. There might be plenty of misinterpreted texts, delays on the road and in the air and rampant miscommunication with friends, family and even crushes. With Halloween plans and early holiday travel on the horizon, those mix-ups could hit especially hard.
Take extra care during this time to double-check things and prepare for the unexpected. We recommend backing up your devices, re-reading any texts before you send them off and trying not to make any big commitments unless absolutely necessary. Things will feel off for a while, and that’s okay. It’s all temporary, and will return to normal before the holiday season is in full swing.
This retrograde will take place entirely in Scorpio, a water sign known for its intensity, secrecy and emotional depth. That can make this an especially heavy period, with old grudges, trust issues and hidden feelings rising to the surface. People might be even more likely to read hidden meanings into things that were never there and hurt their own feelings as a result. It’s important to not just focus on your own resiliency during this period, but to also be extra mindful about how you speak to others and how your words may be misinterpreted.

What You Actually Should Do During Mercury Retrograde
Mercury retrograde shouldn’t have to mean locking yourself indoors and refusing to engage with the outside world in case something goes wrong. Instead, think of it as a period of reflection and forging stronger connections among the relationships you already have.
Focus on meditation, journaling and reviewing your goals, without making any major steps, and make plans for relaxed hangouts with a friend or two. We actually think the slower pace of retrograde can beautifully complement the cozy energy of fall if you’re willing to lean into it.

Mercury Retrograde in Scorpio: What to Expect
Mercury retrograde in Scorpio channels the sign’s intuition and instinct in a way other signs aren’t used to. You might be convinced you’re reading someone’s mind and finding the hidden meaning behind their words, when really you should take them at face value. Jealousy and suspicion may also run high, so be mindful of the tricks your emotions can play. If you’re a Scorpio, expect distance and mystery to feel even stronger than usual, but your loyalty to close friends should carry you through. For more on how every sign is affected, see Mercury Retrograde and Your Zodiac Sign: What to Expect.
Which Zodiac Signs Will Feel This Retrograde the Most?
Sorry, water signs, but we expect this retrograde to impact you more than the others. Scorpio, Cancer and Pisces are all bound to feel the full effects of Mercury retrograde in Scorpio and be more prone to moodiness and struggles with expressing themselves.
The fire signs—Aries, Leo and Sagittarius, will also be influenced during this time, struggling against the laidback pace of retrograde when all they want to do is go, go, go. We suggest they slow down whenever possible to avoid burning out and making mistakes it’ll be hard to reverse later.
And while the earth signs of Taurus, Virgo and Capricorn are more grounded and less prone to be affected by flights of fancy and misunderstandings, they may also begin to feel stuck as their hard-working natures drive them to pursuits they’re not ready to tackle.
Finally, we think the air signs will feel this retrograde the least with their breezy, slightly oblivious attitudes. They’re no strangers to being misunderstood and fighting to be heard, so it might feel like just any other day.
