In reply to spacecadetjake:
Where in Sweden will you be? In the south (ie Malmö/Helsingborg area), there are a couple of small crags - Soffabacken, which has a reasonable amount of decent single pitch, but, as it is located in a forest valley, probably won't be dry until around March, and Kullaberg, which is primarily single pitch trad but has a small selection of sport routes. If the weather is clear, though, it's possible to have a decent day at Kullaberg, and we spent a Sunday in early November there in nothing but T-shirts! There are also some pretty good topos on the website that Toby posted a link to.
I can't really speak for further north, as I've not been there yet, but Bohuslän is the name of the area near Gothenberg which I've heard to be decent - There's a guidebook which is out of print, I believe, and fairly difficult to get hold of, but if you're interested have a look here
