Mercury Retrograde in Scorpio (October 24 – November 13, 2026): Every Date to the Minute, the Venus Overlap, and a Checker for Your Own Chart

Mercury walked into Scorpio this morning.

Not that anyone noticed. Sign changes for the fastest planet happen about every three weeks and rarely make the news. This one is worth a note in the calendar, though, because Mercury is not going to leave. It entered Scorpio at 11:40 UTC on September 30 and does not enter Sagittarius until December 6: sixty-seven days in a sign it usually crosses in two or three weeks. Somewhere in the middle of that long stay, between October 24 and November 13, it turns around and goes backwards. That is the retrograde everybody will be talking about by Halloween.

Mercury retrograde is the one piece of astrology that has escaped into the general culture, which is exactly why it is so badly understood. It is blamed for everything and explained by almost nobody. So this guide does the unglamorous thing: it gives you the actual dates, computed to the minute in UTC and converted to US Eastern (including the awkward clock change on November 1), it explains what the shadow and the storm and the cazimi are, and it hands you a calculator that checks your own chart against the exact degrees instead of asking you to squint at a table. Then we get to what to do about it.

The complete timeline

Times are computed, not copied. UTC first, then New York. Note that US clocks fall back on November 1, so events before that date are EDT (UTC−4) and events after it are EST (UTC−5). Anything landing before about 5 AM UTC is the previous evening in the Americas.

Two things jump out of that table. First, the retrograde proper is only 20 days and 9 hours — short even by Mercury's standards — but the full story, shadow to shadow, is eight weeks. Second, look at how crowded October 24 is: the Sun meets Venus at 03:32 UTC and Mercury stations at 07:11. Two inner-planet turning points in one four-hour window, both in the first degrees of Scorpio's season. If you want one date to circle, it is that one.

What a Mercury retrograde actually is

Mercury orbits the Sun in 88 days; we take 365. Every 116 days or so, on average, Mercury laps us on the inside, and for about three weeks around that moment it appears — from our moving viewpoint — to drift backwards against the stars. Nothing reverses. It is the same effect as the slower train seeming to roll backwards when yours overtakes it. But astrology has never been about what planets do; it is about what they look like from here, and from here Mercury spends roughly 18% of its life going the wrong way. Three times most years, occasionally four.

A few words that get thrown around loosely, defined properly:

• Station. The moment Mercury's apparent motion is exactly zero, as it changes direction. There are two per cycle: the retrograde station (October 24) and the direct station (November 13). Astrologers treat stations as the loudest days of the cycle, and the hours around them as the time when the planet is "strongest" for good or ill. Mercury sits within a degree of its station for about four days either side.
• Shadow. The stretch of zodiac Mercury covers three times: forward, backward, forward again. This cycle it is 5°01′ to 20°58′ Scorpio. The pre-retrograde shadow runs from October 4, when Mercury first reaches 5°01′, to the station on October 24; the post-retrograde shadow runs from November 13 to November 30, when it finally clears 20°58′. The traditional reading: what shows up in the pre-shadow is the subject of the retrograde; the retrograde is the rewrite; the post-shadow is the clean copy.
• Storm. A more recent term for the window in which Mercury is moving unusually slowly, typically defined as under 40 arcminutes a day (its normal pace is well over a degree). By that definition the storm runs from October 17 to November 17. It is a better predictor of the "everything is slow and slightly wrong" feeling than the retrograde dates themselves, because a planet crawling forward at 10′ a day is, for practical purposes, still stopped.
• Inferior conjunction, or cazimi. The exact middle of the retrograde, when Mercury passes directly between Earth and the Sun: November 4 at 14:20 UTC, 12°10′ Scorpio. Before it, Mercury is an evening star, setting after the Sun; after it, a morning star, rising before dawn. Traditional astrology calls a planet within 17 arcminutes of the Sun's centre cazimi, "in the heart of the Sun", and treats it as the one bright spot in an otherwise weakened condition — the moment of clarity in the middle of the muddle. Modern astrologers use the day for the decisive realisation, the honest conversation, the signature you genuinely cannot postpone.

The water year: why 2026 is unusual, and what 2019 can tell you

Mercury's retrogrades do not scatter randomly around the zodiac. Because of the way its 116-day cycle beats against our year, the three retrogrades of any given year fall roughly 120° apart — which is why they tend to land in the three signs of a single element — and the whole pattern slides slowly backwards through the zodiac, spending about two years in each element before slipping into the previous one. 2021 was an air year (Aquarius, Gemini, Libra). 2023 was earth (Capricorn, Taurus, Virgo). 2024 and early 2025 were fire. And 2026 is water: Pisces in February–March, Cancer in June–July, Scorpio now.

What makes 2026 stand out is that all three retrogrades stayed inside their sign from station to station. That is not rare in itself — a little over half of all cycles do it — but three in a row with no sign-hopping, all in one element, gives the year a coherent theme, and the theme of water is emotional information: what you feel, what you remember, what you have not said. February's Pisces retrograde was about the vague and the unfinished; July's Cancer one about family and home; the Scorpio one is about the things that were deliberately not said. Secrets, debts, shared money, passwords, the conversation that was closed too early.

By 2027 the pattern starts to slide back into air: February 9 – March 3 begins in Pisces and ends in Aquarius; June 10 – July 4 goes Cancer to Gemini; October 7 – 28 starts at 4°55′ Scorpio and ends at 19°18′ Libra. So next autumn's retrograde begins almost exactly where this one ends. Astrology is fond of that kind of echo.

For a rehearsal, look at October 31 – November 20, 2019, the last time Mercury did an entire retrograde inside Scorpio (27°38′ back to 11°35′). Within the whole span of 2014 to 2036, 2019 and 2026 are the only two. The degrees are different — this one sits lower in the sign — but the sign, the season and the mood are the same. If you kept a diary in November 2019, the first week of it is worth re-reading. For anyone with the sense that a specific old subject is coming back around: it probably is, and it is probably the one from then.

The Venus overlap: two retrogrades in one sign

The thing that makes this cycle genuinely different from an ordinary Mercury retrograde is company. Venus stationed retrograde at 8°29′ Scorpio on October 3, and although it backs into Libra on October 25, the two retrogrades run together from October 24 until both planets station direct on November 13 — Mercury at 10:51 in the morning, New York time, Venus at 7:24 that evening. A double retrograde of the two personal planets is not exotic (it happens most years somewhere), but a double station on one calendar day is worth noticing, and having Mercury turn around in the very degrees Venus covered three weeks earlier is what gives the autumn its layered, back-and-back-again feel.

There are three dates where the two actually meet or hand off:

• October 6–7 (00:01 UTC on the 7th, 8:01 PM Eastern on the 6th): Mercury, still direct and moving fast, catches Venus, already retrograde, at 8°13′ Scorpio. First pass of a conversation about money or love that will not be finished in one sitting. Mercury will be back at this degree on November 7–8, retrograde and without Venus, and a third time on November 20.
• October 24: the Sun–Venus inferior conjunction at 03:32 UTC, then Mercury's station at 07:11. Venus at the heart of the Sun and Mercury standing still, within four hours, in the first degree of Scorpio season. This is the loudest day of the autumn.
• November 13: both stations. The days on either side are when reversals of reversals happen — the decision that was cancelled comes back; the person who went quiet writes; the price that was withdrawn is offered again.

The practical implication of the overlap is simple: the usual Mercury-retrograde caution about signatures and agreements applies doubly to agreements about money and relationships. A contract about a website can be redone. A joint bank account or a prenuptial agreement drafted under two retrograde planets in Scorpio is the kind of thing astrologers of every tradition would tell you to date after November 13, or after November 30 if the choice is yours. The Venus retrograde guide covers that side of the story, including its own calculator.

The pressure points

Beyond the stations, Mercury makes remarkably few exact aspects during this cycle — the outer planets are simply not where it is going. That is unusual and, frankly, a relief. The dates that matter:

• October 4 — shadow begins (5°01′ Scorpio). Whatever you are dealing with on the first weekend of October is the syllabus. Take notes; you will need them in mid-November.
• October 7 — Mercury conjunct Venus (8°13′ Scorpio). See above. The opening line of the term's main conversation.
• October 17 — storm begins. Mercury drops below 40′ a day. From here to the station, expect the pre-retrograde symptoms that people always report a week "early": the delayed reply, the double-booked meeting, the file that will not open.
• October 24 — station retrograde (20°58′ Scorpio), four hours after the Sun–Venus conjunction. Mercury is standing still in the third decan of Scorpio, an evening star 20° east of the Sun. This is the day misunderstandings are born. Say less, write down more, and do not send anything that cannot be unsent.
• October 26 — Full Moon at 2°45′ Taurus. The Moon opposes the Scorpio Sun and Venus in the first degrees of the sign two days after the double turning point. Full Moons illuminate; this one lights up whatever the retrogrades just reopened, on the axis of money and worth.
• October 30 — Mercury square Mars (17°58′ Scorpio / Leo). The single exact hard aspect of the whole retrograde, and it lands on the Friday before Halloween. Retrograde Mercury squaring Mars is the classic signature for the message sent in anger, the argument that escalates by text, and the mechanical failure at the worst moment. Drive carefully, argue in person, and if it is a fixed sign matter (Taurus, Leo, Scorpio, Aquarius around 16°–20°), let it wait.
• November 4 — inferior conjunction / cazimi (12°10′ Scorpio). Mercury is moving backwards at its fastest, 1°18′ a day, right through the Sun. The midpoint of the retrograde and, for the traditionalists, its one dignified hour. Venus sextiles Jupiter the same morning. If you are going to have the conversation, this is the day the other person is most likely to hear it.
• November 9 — New Moon at 16°53′ Scorpio. The Scorpio New Moon with Mercury retrograde at 6°51′ in the same sign. New beginnings under a retrograde Mercury tend to be restarts of old projects rather than genuinely new ones. That is fine. Restart the old project.
• November 13 — station direct (5°01′ Scorpio), then Venus station direct. The turn. Mercury is now a morning star, 16° west of the Sun. Things that were stuck start to move over the following week, but see the next entry.
• November 17 — storm ends. Mercury back above 40′ a day. The realistic "it's over" date for anyone who cares about how it feels rather than the technical direction.
• November 30 — shadow ends (20°58′ Scorpio). Mercury clears the station degree, and the subject of the last eight weeks can finally be filed. December 6 it enters Sagittarius and changes the subject entirely.

One non-event worth mentioning: Mercury stations direct at 5°01′ Scorpio, which is just under two degrees from an exact square to Pluto at 3° Aquarius. It never perfects the square, but it turns around in its shadow. For anyone with planets at 3°–5° of the fixed signs, the November 13 station will feel like a Pluto contact — heavier, more final — even though the ephemeris will not list one.

Your rising sign: the house being audited

Because the whole retrograde stays in Scorpio, it stays in one house of your chart from shadow to shadow, which makes the rising-sign reading unusually clean. Whole-sign houses; if you use Placidus the house can differ by one. If you only know your Sun sign, read that instead — it will be right more often than you would think, and the calculator above can make it exact.

What to do, what to put off, and the contract question

The folk wisdom says: don't sign, don't buy electronics, don't travel, don't start anything. Taken literally that would remove three weeks from every four months, which is absurd, and most working astrologers do not live that way. The more useful version is a distinction between new and re-. Mercury retrograde is bad at new — new contracts, new devices, new plans made with strangers — and unusually good at anything beginning with re: review, revise, repair, reconnect, research, reconsider, rest. The Scorpio flavour adds: investigate, audit, and say the thing that was left unsaid.

On the specific question everyone asks — can I sign a contract? — the honest answer has three parts. If the date is not yours to choose, sign it and read it twice; astrology has never asked anyone to lose a job over a transit. If the date is yours to choose and the agreement is about money, property or a relationship, the cleanest dates are after November 13 (technical), after November 17 (storm), or after November 30 (thorough), and this autumn the Venus retrograde makes that advice stronger than usual. And if you must sign inside the window, the traditional pick is November 4, the cazimi, when Mercury is "in the heart of the Sun" and its judgment is considered clearest.

A short, unmystical checklist for this particular retrograde, given the sign:

• Before October 17: back up your phone and laptop; renew anything expiring in November; book travel for the holidays now if you can; download the statements for any shared account.
• October 17 – November 17: reread before sending; confirm meetings the morning of; do not change passwords, banks or phone carriers unless forced; expect to hear from at least one person from 2019.
• The three re-words for Scorpio: research (the thing you were told and did not check), reconcile (the account, and possibly the person), release (the grudge that costs more to carry than it would to set down).
• After November 30: file it. Whatever the last eight weeks were about, it is done. Sagittarius Mercury from December 6 will not want to discuss it again.

Born with Mercury retrograde (and the four Mercury types)

About one person in five was born while Mercury was retrograde. The calculator above tells you in a second, but the popular description is recognisable enough that many of them already know: a mind that takes information in sideways, thinks before it speaks (and sometimes long after), dislikes being rushed to an answer, and is often better on the page than out loud. The stereotype that natal Mercury retrograde means "bad at communicating" does not survive contact with the people who have it; a striking number are writers, editors, researchers and the person in the meeting who says nothing for forty minutes and then the one thing that matters.

The other thing they report, consistently, is that transiting Mercury retrogrades bother them less. That is not a superstition with a mechanism behind it, but it is an observation old enough to be worth passing on: if you were born with the software running backwards, everyone else's three weeks of confusion is your home turf.

There is a subtler classification that deserves to be better known. Dane Rudhyar pointed out, in a scheme later astrologers have filled in, that Mercury is always either ahead of the Sun in the sky — rising before it, a morning star — or behind it, setting after it, an evening star, and that combining this with direction gives four Mercury types. The calculator reports yours.

• Morning star, direct (Rudhyar's Promethean): quick, forward-leaning, speaks while the thought is still forming and thinks by talking. The largest group.
• Morning star, retrograde: the intuitive leaper. Reaches conclusions ahead of the evidence and then works backwards to explain them; often right, rarely able to say why.
• Evening star, direct (Epimethean): reflective and deliberate. Understands things fully once they have happened; the careful drafter and the good witness.
• Evening star, retrograde: the deepest reviewer. Slow to speak, difficult to fool, inclined to reopen a question everyone else considered closed, and usually vindicated for it.

Rarer still: Mercury stationary at birth, within about a day of turning around (the calculator flags it below 0.12° a day), which astrologers have long read as a concentrated, one-track mind; and Mercury cazimi, within 17 arcminutes of the Sun, which happens for a few hours around each conjunction and is read as unusual clarity of purpose. If you were born on November 4 this year, or on March 7 or July 13, 2026, you may want to check.

All 2026 and 2027 dates, and every retrograde 2020–2030

The six cycles from this year and next, with shadows and the inferior conjunction for each. UTC and New York times both given; the Eastern column accounts for daylight saving. The current cycle is highlighted.

Notice the 2027 pattern: every one of next year's retrogrades starts in a water sign and ends in an air sign, as the element pattern slides back. The next entirely-single-sign cycle is January 24 – February 14, 2028, in Aquarius.

Method and sources

• All planetary positions are computed from the JPL/Standish approximate Keplerian elements (valid 1800–2050) with precession applied to give tropical longitudes of date; stations are found by bracketing the zero of apparent longitude speed to the minute. Validation against published ephemerides: the November 9, 2025 station computes to 6°51′ Sagittarius and the November 29, 2025 station to 20°42′ Scorpio (both match the published figures exactly); the August 5 and 28, 2024 stations to 4°06′ Virgo and 21°24′ Leo (exact); the October 24, 2026 station to 20°58′ Scorpio at 07:11 UTC (published: 20°58′–20°59′, 07:12 UTC) and the November 13 station to 5°01′ Scorpio (published 5°01′–5°02′).
• Lunations use a 60-term truncation of the Meeus lunar theory, accurate to a few minutes. Aspect and ingress times are good to about ±15 minutes; station times are quoted to the minute for consistency but are physically fuzzy, since Mercury is nearly motionless for many hours either side.
• US Eastern conversions use the IANA America/New_York rules: EDT (UTC−4) until 2:00 AM on November 1, 2026, EST (UTC−5) afterwards.
• "Storm" is defined here as apparent speed below 40 arcminutes per day; "cazimi" as within 17′ of the Sun's centre; "shadow" as the degree range between the two stations. Houses in the rising-sign table are whole-sign. The four Mercury types follow Dane Rudhyar's morning-star/evening-star (Promethean/Epimethean) scheme.
• Where we state a percentage (about 18% of births with Mercury retrograde, 7% with Venus retrograde) it is the fraction of time the planet spends retrograde, which is the same thing over a large enough population.
• This is astrology, not advice. Sign the contract, buy the phone, text the person from 2019 or don't, on your own judgment. We just do the maths.
