Scorpio Sun aims to understand what is really going on, including the parts nobody says; Aquarius Moon needs room, and not to have your feelings interpreted for you. The two signs are three signs apart, which is what decides whether those two agree, and it also tells you the lunar phase you were born under.

Scorpio Sun, Aquarius Moon: a square, 90 degrees.
The short answerScorpio Sun with Aquarius Moon means you are aiming to understand what is really going on, including the parts nobody says, while needing room, and not to have your feelings interpreted for you. The two signs are three signs apart, a square, 90 degrees, so the aim and the need pull against each other. It also means you were born somewhere in the first quarter moon part of the cycle.
Scorpio Sun: what you are trying to become
The Sun is the aim. Not what you are like, which is a different question, but what you are consciously oriented toward and what you would be proud of being. With the Sun in Scorpio that is to understand what is really going on, including the parts nobody says.
What Scorpio quietly takes pride in is honesty about hard things. At its best this placement becomes somebody who can be told anything. Scorpio is Water and Fixed, ruled by Pluto and Mars, and the recognised weak spot is that it tests people before trusting them.
Aquarius Moon: what you need
The Moon is the private half, and it is usually the placement people recognise most sharply once it is described. It covers what you need in order to feel alright and what you do before you have thought about it. With the Moon in Aquarius you need room, and not to have your feelings interpreted for you.
What settles you: distance, a problem to think about, friends who do not fuss. And the giveaway, the thing people close to you would recognise: becomes very reasonable, which is the sign it is bad. Aquarius is Air and Fixed, ruled by Uranus and Saturn.
What happens when you put the two together
Scorpio and Aquarius are three signs apart, which is a square, 90 degrees. The friction one. What you are trying to become and what you need in order to feel safe actively pull against each other, so progress tends to cost comfort and comfort tends to cost progress.
Water and Air are different elements, which is the part that actually produces the mismatch people notice: you are aiming with one kind of energy and recovering with another.

The practical version
Because the two disagree, you will recognise this: the thing you are working toward keeps costing you the thing you need. To understand what is really going on, including the parts nobody says does not sit comfortably with needing room, and not to have your feelings interpreted for you, and most people with this combination have arranged their life around the tension without ever naming it.
The useful move is not to pick a side. It is to notice which one you default to when you are tired, because that is almost always the Moon, and to notice what you have been postponing, because that is almost always the Sun.
The phase you were born under
There is a second thing these two placements tell you, and almost nobody mentions it. The distance from the Sun to the Moon, counted forwards, is the lunar phase you were born under. Aquarius is 3 signs ahead of Scorpio, which puts you in the first quarter moon band.
That is a band rather than a verdict: the exact phase needs the degrees, not just the signs, so somebody at the edge of a sign could land either side of it. What a first quarter moon birth is read as is here, along with the arithmetic to check your own properly.
What this page is missing
Your rising sign, which is what people meet first and which needs a birth time. On any given day, twelve different people share this Sun and Moon and have twelve different rising signs, and they do not come across remotely alike.
Two placements out of about fortyThe Sun and Moon are the two biggest things in a chart and they are still two things. The rising sign, which needs a birth time, is what people meet first and is missing from everything on this page. So is every house, every aspect to anything else, and the whole of Mercury through Pluto. A Sun and Moon reading is a sketch, and a sketch that fits is not evidence of anything beyond the sketch being well drawn.
You aim to understand what is really going on, including the parts nobody says while needing room, and not to have your feelings interpreted for you. The two signs are three signs apart, so those pull against each other.
Is Scorpio Sun Aquarius Moon a good combination?
It is a demanding one, and that is not the same as bad. The friction is what forces people with this combination to examine themselves, which most comfortable combinations never have to.
Do I need my birth time for this?
Not for the Sun. For the Moon, often yes: the Moon changes sign every two and a half days, so anybody born on a day it moved needs a time to be sure.
What lunar phase was I born under?
Aquarius is 3 ahead of Scorpio, which puts you in the first quarter moon band. The exact phase needs degrees rather than signs.
