Hi Adam,
Is this your first time to either Mello or Orco or Finale? This time of the year you would be baking everywhere in Italy. Instead... we've had so much rain that we've never seen in centuries... The weather has gone mad. I've never been to Mello (Val Masino), my friends say it would be too hot and in fact yesterday I've climbed in Orco with some friends from Milan.
Now...
In Orco if it rains you haven't got much choice. There are two sheltered sport crags: Bosco and Falesia di Luca (both featured on Oviglia's guidebook). Bosco is a little nicer than Falesia di Luca. Neither is great, I'm afraid, they have chipped holds
However, rock will dry quickly when it stops raining. Not everyone knows that the central lines at the Droide above Ceresole, past the tunnel, not only they're the only two trad lines (one useless bolt half way), but they're also dry in the rain. A couple of more extreme sport routes to the left which also looked dry in the rain last Sunday when... it rained. Though I suppose a proper downpour would make no prisoners... Avoid all dihedrals, e.g. Diedro Nanchez
, it's been raining quite a bit, they're normally wet in August, this year thell be even wetter.
Just off Orco, you'll find the Piantonetto Valley (look for Rock Paradise, Oviglia's original guidebook to the area). Weather is very changeable, if it rains in one valley, it doesn't mean it's raining in the one next to it. In Piantonetto there's plenty more. The most accessible (walking wise) buttress is Scoglio di Mroz with some really cool classics. If you're looking for alpine adventure and a summit, google Becco di Valsoera. You'll need two days of decent weather for that.
Also parallel to Orco there's Vallone di Sea, an off-the-beaten-track little climbing paradise with a mix of trad, sport and mixed longer lines as well as boulders. They held a climbing meeting last weekend. Hard to find info about this area, if you do end up there, drop me a line, happy to help.
If cragging is your thing, also consider going to Cadarese and the Ossola area in general all the way into Switzerland (Gondo area). The central sector of Cadarese (lines around Edera) are normally dry in the rain. If it gets too hot, Cadarese may be out of the question - again.... it should be out of the question
- you may want to venture up to Yosesigo (north facing, ~40 mins walk) aka Full Metal Jacket. More info here:

Finally, if the weather changes abruptly and the Italian summer hits the country... go as high as you can
Good luck!
Ciao!
Nic
PS: I hope someone will give you some beta on Mello too.
PS2: Forgot to say. Don't go to Finale. Not in August. Not for climbing. It's wrong regardless the weather. Trust me
