In reply to Reedie:
There are some facebook groups you could try:
Central Belt Trad Collective
North East Outcrops
Scottish Rock Climbing Partners
If you are on facebook that is.
Also, if you fill in your UKC profile with a mugshot and some info about yourself, you are more likely to get someone in this thread offering to take you outside.
You should state as well if you are looking to get into sport climbing outside or trad climbing or both, the transition to sport climbing from indoors is a more natural progression - lets you get used to reading the rock and doing moves you wouldn't do indoors - before moving on to learning all the extra stuff you need to know to trad climb. Sport climbing is also a less risky undertaking with a novice partner than trad, so probably easier to find an experienced person to take you out on sport than on trad.
Finally, as someone else said, you probably got about 2 more weeks of marginally ok weather before it all gets a bit cold and wet for outdoor climbing.
