In reply to henry castle:
Valle Cochamo in Chile - big, multi-pitch granite nirvana and/or Frey in Argentina - smaller package routes but quality climbing.
Tasmania - routes are not huge but great variety of stone and styles...crack, face, slab. Our winter is a good time to go.
Wadi Rum in Jordan, Oman limestone (much of it is trad), even UAE seems to have some stuff but have not been.
Some reliably dry/warmish places in the US: Red Rocks, NV; Cochise, AZ (free camping options); Moab esp. towers (could be very cold in the dead of winter but typically dry); Joshua Tree (...probably not worth the long trip but that's just an opinion); Zion (again, could be cold & even snowy in dead of winter).
Some single pitch cragging areas around MX City (Los Dinamos &...I forget the name)...combined with some multi-pitch (yes - bolted) climbing around central Mexico would make for an interesting trip I think.
