Sector Bruixes at Terredets is pretty good for this. I doubt it'll be sun bathing temperatures but it gets plenty of sun. Its moderately overhanging, maybe 20 odd degrees (plus a small cave on the right hand end), and the rock is very skin/tendon friendly. Most routes are 7b+-8a+, if you onsight around that grade then there won't be enough for a month, though there are some upper 8's in the cave. Lower grade wise there's not much at that sector, a few low 7's, and maybe a couple 6's but I got the impression that they weren't very good. There are other sectors nearby, e.g. Sector Regina for more sport climbing but its North facing, and some multipitch sectors which I don't have any details on.
