Mercury in Sagittarius, 2025

Mercury leaves Scorpio and enters Sagittarius on 29 October 2025 at 11:02 UTC. Sagittarius is a mutable fire sign ruled by Jupiter. This stay is short and not straightforward. Mercury turns retrograde on 9 November 2025 while still in Sagittarius, then slips back into Scorpio on 19 November 2025 at 03:20 UTC, after 21 days. The retrograde period continues until 29 November 2025.

Astrologers read Mercury in Sagittarius as a mind that thinks in big pictures: questions of meaning, travel, study and belief, spoken with frankness and humor. The tradition also notes a tendency to skip details in favor of the broad idea. Because Mercury turns retrograde during this visit, many astrologers suggest using the later weeks to revisit plans rather than launch them. One modest habit is to write down what a generous promise will actually take before making it.
