A new Mercury retrograde begins on November 9, 2025, starting in Sagittarius. This retrograde runs through November 29, though Mercury remains in Sagittarius only until November 18, when it backtracks into Scorpio. While the transit is relatively short in Sagittarius—about nine days—it coincides with other planetary activity that can amplify its effects. Mercury won’t return to Sagittarius in retrograde again until December 2030.
Mercury retrogrades are known for disrupting communication, technology, travel, and plans. This brief passage through the Fire sign Sagittarius emphasizes themes of freedom, beliefs, travel, and higher education. Because the retrograde aligns with other transits this month, you may feel its influence more strongly than the nine-day window suggests.
What is Mercury retrograde?
In astrology, “retrograde” describes the apparent backward motion of a planet through the zodiac. Because Mercury usually moves quickly and smoothly, its apparent reversal tends to throw communication, logistics, and technology off-balance. All planets except the Sun and Moon have retrograde periods; Mercury’s retrogrades occur about three to four times a year and typically last around three weeks, making them frequent but shorter than most planetary retrogrades.
Mercury governs messaging, travel, data, and devices, so those areas are often the first to show signs of disruption—delays, misunderstandings, technical glitches, and mixed signals. Despite the frustrations, Mercury retrograde also provides a valuable opportunity to revisit, revise, and restore: think rework, reconnect, rethink, and renew. It’s a natural time to give something a second try or attend to unfinished business.
On a personal level, the retrograde’s influence will play out in the parts of life ruled by the zodiac sign it occupies and by the house in your natal chart where it occurs. If you don’t know your birth chart, consider generating one so you can locate your Sagittarius house and see where this energy lands in your life.
Impact of the 2025 Mercury Retrograde in Sagittarius
With Mercury turning retrograde in Sagittarius, you may feel a stronger need for space and freedom. Sagittarius resists confinement and values exploration, so feelings of impatience, restlessness, or a desire to break free can surface. This period can be productive if you act thoughtfully rather than impulsively. It may also be a time to revisit past travels, studies, or beliefs—repairing or refining them rather than seeking entirely new directions.
Expect potential travel hiccups, delays, or cancellations, but also opportunities to return to places and experiences you’ve enjoyed before. Sagittarius rules higher education and philosophy, so colleges, courses, and belief systems might be up for review. You could find yourself reexamining convictions or taking up study again. This retrograde can sharpen your passion for causes you care about—use that energy to advocate thoughtfully rather than force opinions onto others.
3 Major Events With the Sagittarius Mercury Retrograde
1. Mars in Sagittarius
Mars enters Sagittarius on November 4, five days before Mercury turns retrograde. Mercury starts the retrograde conjunct Mars, and their alignment peaks around November 12–14. Mars brings drive, urgency, and a readiness to act, which can amplify Mercury’s retrograde intensity. You may feel compelled to move quickly, but impulsive decisions can lead to regret. On the positive side, this energy supports taking initiative on second chances that require courage and leadership.
2. Taurus Full Moon and Uranus returning to Taurus
A Taurus Full Moon on November 5 elevates emotional intensity just before this retrograde. Two days later, Uranus retrogrades back into Taurus, reintroducing long-term change themes that have been unfolding since 2018; Uranus will leave Taurus for good in April 2026. The Full Moon highlights emotional focus around these changes, and Uranus’s return can prompt unexpected developments. Together with Mercury retrograde, this combo encourages completing shifts you’ve been working on—offering an opportunity for a second chance to finish or revise important transitions.
3. Jupiter retrograde begins November 11
Jupiter, ruler of Sagittarius, turns retrograde on November 11—just two days after Mercury. Jupiter retrograde slows expansion and can make forward momentum feel limited. Because Jupiter rules Sagittarius, its retrograde amplifies the retrograde atmosphere, encouraging introspection, review, and reevaluation of goals, beliefs, and long-term plans. This is a time to be flexible, pause, and revisit missed opportunities rather than pushing for new beginnings.
