In reply to duchessofmalfi:
Fantastic climbing but as far as temperature is concerned, that's pretty much personal preference, I'd look up the climate statistics. If you don't know what average daily maximum temperature suits you for climbing, look up the values for climbing destinations you have already climbed at and found the weather agreeable.
Personally I enjoyed Sicilly in the depths of winter but for me an average daily maximum for 15C is probably "climb in the shade" and anything much above 17C is "meh, go somewhere cooler".
