Messenger planet Mercury turns retrograde several times each year, disrupting the flow of information and communication. All about the 2025 Mercury retrogrades, partially excerpted from The AstroTwins’ 2025 Horoscope book, the annual guide to the stars.

2025 Mercury retrograde dates and zodiac signs

Messenger Mercury is the planet of communication, social networks and data. When it flips into reverse three to four times each year, it affects our immediate, day-to-day lives. Misunderstandings flare, old friends (and exes!) pop up in our feeds and information gets in the wrong hands. Yikes!

But don’t believe all the negative hype. While Mercury retrograde can (and will) scramble signals, these three-week cycles can be a positive time for all re activities: reviewing, revising, reconnecting, reuniting. Tap the brakes on fast-moving projects and surrender to nostalgia. Develop projects behind the scenes so you can be ready for a reveal once Mercury turns direct!

When are the 2025 Mercury retrogrades?

Here are all the 2025 Mercury retrograde dates, the zodiac signs they’re in, and what to expect so you can plan ahead.

Mercury retrograde in ARIES and PISCES

March 15-29, 2025 (Aries), March 29-April 7, 2025 (Pisces)

Brace for impact! Mercury darts into its first retrograde of 2025 on March 15, 2025, muddling communication and throwing a wrench into neatly ordered plans. Until March 29, the messenger planet reverses course in the fiery sign of the Ram, sparking a period of heated communications and hasty decisions.

Tempers will flare as words fly without thought. Go easy on the smack-talking and careful not to start any needless rivalries. Aries inspires quick action, but retrograde demands caution. It may be necessary to pump the brakes on projects that require a more aggressive approach. Fine-tune personal goals and actions, ensuring they truly align with your ambitions.

When Mercury reverses into Pisces on March 29, you can access a deep level of creativity and divine inspiration that supports rapid growth once the retrograde ends on April 7. Patience and precision are your allies now, so adjust your sails accordingly.

Mercury retrograde in LEO

July 18-August 11, 2025

Roll up the red carpet! As Mercury pivots into a three-week retrograde in glamorous, flamboyant Leo, on July 18, 2025, it’s better to fly under the radar than risk getting overexposed. Scrambled romantic signals, celebrity breakups and flagrant fashion faux pas will interrupt your summer program.

Hold off on bold style choices and save any risky cosmetic procedures until after August 11. Exes might resurface, and lovers’ quarrels could ignite out of nowhere. With Mercury’s backspin in Leo, however, there’s a risk of being too lowkey.

Conflict resolution will be challenging, and blame-shifting could backfire. The best way to navigate this turbulent phase is to stay humble and keep your heart open—without being overly trusting, too soon.

Leo rules our “kings and queens,” and this retrograde could reveal some fascinating (and perhaps disturbing) information about those in power. Before stepping into a leadership role, make sure you know what you’re getting into. Heavy is the head that wears the crown—at least until August 11.

Mercury retrograde in SAGITTARIUS and SCORPIO

November 9-18, 2025 (Sagittarius), November 18-29, 2025 (Scorpio)

Please DON’T say the quiet part out loud. Big-mouthed Mercury spins retrograde in tactless Sagittarius for the last retrograde of the year on November 9, 2025, flashing a code red blurt alert. This three-week cycle lasts until November 29, but before Mercury moves back into Scorpio on November 18, honesty can be particularly brutal, smashing relationships to smithereens.

If you don’t want to spend the holidays estranged from your nearest and dearest, think twice about going on any attacks, even if you’re “just trying to be helpful.” Equally disruptive are off-color remarks and X-rated humor which could fall flat with a general audience. Visiting loved ones might require extra precautions during this argumentative time. If you need to cut a trip short or stay at a hotel to preserve the peace, err on the side of personal space. Leave early for the airport and triple check all reservations since this retrograde can be particularly disruptive of travel.
