Replying to Europe summer glacier skiing

so me and a few buddies across Canada are missing the peak time to ride our usual whistler glacier as we are all booked with plans until mid-end of july, (where north american summer skiing basically goes to shit). So basically to get the good conditions we're forced to go to europe, now at first we were thinking fonna glacier in norway, where the summer season goes up until september, but my buddy is worried about conditions going bad mid august, anyone have any info on this and/or european skiing in general???
