What Astrology Has To Say About Taylor Swift and Joe Alwyn?
When Taylor Swift and Joe Alwyn began their relationship in 2017, it marked a notable departure from her typical pattern. She is a Sagittarius, one of the most outwardly expressive signs in the zodiac. He is a Pisces, a private water sign guided by sensitivity and depth. By Sun sign alone, the pairing is unconventional, but astrology rarely stops at the Sun, and the full picture of their charts explains a great deal about why they worked for as long as they did, and what the tensions looked like beneath the surface.
The short answer: Taylor’s Sagittarius fire found something grounding in Joe’s Pisces nature, but Sagittarius ultimately needs forward momentum, and the long-term pressures of Saturn made the structure difficult to sustain.
Taylor Swift as a Sagittarius
Sagittarius is ruled by Jupiter, the planet of expansion, optimism, and reaching beyond the familiar. A Sagittarius woman at her core is an archer: she aims at something meaningful, fires, and moves. She tends toward directness, candor, and a genuine love of exploration in every sense, intellectual, physical, and creative.
Taylor’s public persona has followed this pattern throughout her career. She processes experience through her art almost immediately, and she is honest about her emotional life in a way that feels distinctly Sagittarian. She does not hide in ambiguity. Her work names things.
Her chart shows Saturn in a prominent position, which accounts for the discipline and structure that have made her one of the most deliberate artists of her generation. That Saturnian discipline has also meant that her Saturn return, the astrological milestone that typically occurs in the late twenties, was unusually intense. She has described the corresponding period as feeling like a riptide. That cycle directly preceded her time with Joe.
Joe Alwyn as a Pisces
Joe Alwyn, born February 21, 1991, has his Sun in Pisces. Pisces is ruled by Jupiter and Neptune, the planets of vision, compassion, and the dissolution of boundaries. Pisces people tend to be private, imaginative, and emotionally perceptive in ways that are not always visible on the surface. They connect through depth rather than display.
Joe’s public profile during their relationship was notable for its quietness. He gave very few interviews and maintained a deliberate privacy that was entirely at odds with Taylor’s visibility. For a Pisces, that is not evasion; it is simply the natural preference for interior rather than exterior expression.
Where Their Charts Connect
The astrological connection between Taylor and Joe runs deeper than Sun signs. Taylor’s Moon is in Cancer, a placement that makes her emotionally responsive, attuned to home and private life in ways her Sagittarius Sun does not always show. Joe’s Pisces Sun forms a harmonious trine to her Cancer Moon, meaning that at a core emotional level, he was able to reach a part of her that fire and air sign partners typically cannot.
Joe’s Venus is also in Pisces, the sign where Venus is considered exalted: exceptionally sweet, gentle, and idealistic in love. That Venus in Pisces formed a harmonious trine to Taylor’s Mars and Ascendant in Scorpio. The Mars-Venus connection between two people is one of the most reliable indicators of genuine attraction, and when it falls across signs as compatible as Pisces and Scorpio, the chemistry tends to be felt immediately and deeply.
Taylor’s Venus is in Aquarius, which places it in conjunction with Joe’s Saturn. Venus-Saturn contacts in synastry can bring commitment and seriousness to a relationship, but they can also introduce restriction, particularly when other transits are adding pressure. Over time, that Saturn overlay can feel less like steadiness and more like constraint.
The Sagittarius Need for Forward Motion
What astrology also tells us about Taylor Swift is that a Sagittarius woman needs growth and movement. She needs to feel that a relationship is expanding her life rather than containing it. What a Sagittarius woman looks for in a man comes back to this consistently: freedom, honesty, forward momentum, and a partner who is going somewhere.
Pisces and Sagittarius share their ruling planet Jupiter, which creates genuine philosophical and emotional resonance. But they handle the question of forward movement very differently. Sagittarius moves toward the next horizon. Pisces tends to move inward, going deeper rather than further. When those two orientations align, the relationship is rich. When they pull in different directions, there is a natural divergence that grows harder to navigate.
For a sense of how she moves through relationships after a significant ending, how a Sagittarius woman processes a breakup speaks to her need to process, grow, and eventually redirect her energy forward.
What the Charts Tell Us
Taylor and Joe were not an obvious astrological match on paper, but they were a meaningful one. The depth of the water connections in their charts, her Cancer Moon, his Pisces Sun, his Venus in Pisces touching her Scorpio Mars, gave the relationship a quality of emotional resonance that her earlier, more extroverted pairings likely did not have. It brought out a quieter, more introspective side of her that served her well artistically.
What ultimately matters in astrology is not whether two signs are traditionally compatible, but whether two people’s charts create the conditions for growth. For a period, this one clearly did.
