Aunque takes the indicative when the fact is given and known —aunque llueve, salgo, and it IS raining— and the subjunctive when it is a possibility or when you are setting it aside: aunque llueva, salgo, whether it rains or not. The same goes for a pesar de que and por mucho que.
The usual slip. Using the indicative always, and losing a distinction that English marks with two different conjunctions.
Why it catches you out. English says “although it's raining” for one and “even if it rains” for the other: two conjunctions. Spanish uses ONE conjunction and changes the verb instead — so what your language puts in the connector, this one puts in the mood.
