Late Year Mercury Retrograde coming November 9-29, 2025 – What you need to know

By Mark A Leon

When Is Mercury Retrograde?

In astrology, Mercury Retrograde is when Mercury appears to move backwards in the sky (it’s an optical illusion), and astrologers believe it influences communication, technology, travel, and decision-making. 

In 2025, there are three main Mercury Retrograde periods (plus their surrounding “shadow” periods) including the final period of the year, November 9 through November 29.

Before and after each official retrograde there’s also a “pre-shadow” and “post-shadow” period when things may feel sluggish or subtly off even though Mercury is not officially retrograde. 

What Challenges Could It Pose?

Astrologically speaking, Mercury Retrograde is often associated with disruptions and friction in key areas:

1. Communication Mishaps
   Misunderstandings, mis-sent emails or texts, unclear conversations — things that rely on clear messaging may go awry.  
2. Technology Glitches
   Devices might act up: software bugs, crashes, delays in responses, or lost data. It’s the kind of time when you might regret not backing something up.  
3. Travel Delays or Plan Changes
   Tickets, reservations, schedules — travel tends to be more vulnerable. Delays, cancellations, or last-minute changes become more likely.  
4. Contracts / Decisions / Signings
   Because Mercury rules over “messenger” functions, signing agreements or making major decisions during retrograde is often seen as risky. Something might be overlooked or the terms may not be as clear as you think.  
5. Emotional or Mental Frustration
   On a more internal level, people sometimes report feeling more irritable, unfocused, or prone to misunderstandings with others.  

That said, it’s not universally “bad.” Many astrologers see Mercury Retrograde as a time for reflection, review, and revisiting things rather than launching brand-new ones. 

How Can We Prepare?

You can’t avoid Mercury Retrograde — but you can reduce friction and maybe even benefit from it. Here are ways to prepare:

• Back up your data
  Before the retrograde begins, make sure important files, contacts, and documents are saved somewhere safe.
• Double-check communications
  Reread emails, contracts, messages before sending. Slow down when drafting important documents.
• Leave extra margin in travel or scheduling
  Book with some buffer time. Confirm reservations. Be ready for delays or unexpected changes.
• Avoid major launches / signings if possible
  If you can delay a contract signing, a big announcement, or launching a new project until after the retrograde ends, that might reduce risk.
• Use it as a review period
  Instead of pushing forward blindly, consider retrograde time as an opportunity to revisit past projects, review goals, tidy up loose ends, or reconnect with people you haven’t spoken to in a while.
• Practice patience and flexibility
  Accept that not everything will go perfectly. When something doesn’t proceed as planned, treat it as a chance to learn, adjust, and respond rather than get stuck in frustration.
• Reflect inwardly
  Use the energy to journal, meditate, re-examine your routines or communication style. Sometimes the value of Mercury Retrograde is what it teaches you about how you operate when things aren’t seamless.
