In reply to LukeDclimber:
Your best bet between vienna and graz are Höllental (mostly multipitch) and Adlitzgräben (single pitch).
Closer to vienna, Hohe Wand (mainly multipitch) may be a touch hot even considering your migration history, afternoon shade comes around, while peilstein has shade all day.
Alpine, but partially well bolted and cool northfacing stuff is to be found at Gesäuse ... you'll need a rack. Everything from 4-7c and up to 25 pitches.
