Compatibility tends to be high with this combination. Both signs are independent, progressive, individualistic, sociable, freedom-loving seekers of novelty and excitement. These two don’t need to spend every moment together, so they don’t tie one another down or make each other feel oppressed.
Aquarians have a number of traits that increase their compatibility with Aries. Although they love a good debate, unlike Aries, they aren’t usually combative and are not inclined to dominate others, so they’re unlikely to trigger a rebellious Aries backlash (which often occurs with more bossy or controlling types). Aquarians also tend to be tolerant and not emotionally reactive, so they’re unlikely to become upset in response to Aries provocation. In addition, typical Aquarians are collaborative rather than competitive, so they don’t compete directly with Aries, removing another potential source of conflict (the exception to this rule is an Aquarius with a feisty, aggressive rising sign such as Aries or Leo).
One potential problem with this match is that Aquarian emotional detachment may bother passionate, emotionally expressive Aries. Aries is a warm, affectionate fire sign whereas Aquarius is a cool, intellectually focused air sign. Aquarian detachment may make Aries feel insecure or even unloved at times, and this problem can be exacerbated by the Aquarian tendency to spend time with many different people and treat everyone similarly rather than prioritizing a romantic partner. Another problem with this match is that neither sign is particularly sensible, so the practical aspects of life may go unaddressed, leading to problems. However, this is otherwise an excellent pairing unless their ascendants and moon signs are not compatible.
Aquarius and Aries are likely to hold one another’s interest for a number of reasons. Aquarius tends to be unpredictable and open to new experiences, so Aries is less likely to grow bored, and Aries is dynamic, impulsive, and also driven to seek new experiences, so Aquarius won’t suffer a descent into stultifying routine. These two are unlikely to get into a rut because one or the other will promote change at the first sign of things becoming too settled. They keep things lively and interesting, which gives their match more sticking power. In a best-case scenario, Aries strength and decisiveness will have a stabilizing effect on erratic Aquarius, while Aquarius’s tolerant, calm nature helps frenetic Aries become more peaceful and focused.
Note: There is more to astrological compatibility than sun signs alone. Other elements in a person’s natal zodiac also play a role. Ascendants (rising signs), moon signs, and other planetary placements and aspects also shape personality and affect compatibility. For example, a Capricorn with Leo rising will be more extroverted than a typical Capricorn, and a Taurus with Aries rising or the moon in Sagittarius will be more compatible with Sagittarius than a typical Taurus.
