In reply to gavinpeach:
Try to have a look at the webcams in the area:

A report from gulliver.it dating 12 of July:
Still snow at the traverse before Colle del Leone. At Carrel bivouac hard to find any water, no clean snow left.
Good conditions for the climb, crampons only to cross Linceu glacier (10 minutes), due to hard snow and fixed cable partially buried.
At Cervinia they have first hand info though, better to ask there.
