In reply to ElArt:
Yes they dry quite quickly. The forecast for Interlaken and Meiringen looks poor for the next week according to yr.no though.
In contrast Finale Ligure looks ok. Perhaps a rapid trip south to or towards the Med is needed to rescue some of your holiday if you have a car. It is about 260 miles.
There must be some dry crags on the way in Italy too, but I've not climbed at any there, except Finale, so can't recommend anything.
The Schweiz Plaisir Sud guidebook has a selection of crags in Northern Italy. Finale has it's own guidebook that was available locally when I was there a long time ago.
