i'd switch font with the alps. you want to be in the alps now, with hopefully sunny weather and in font with fresh temps, maybe in late september.
in general i'd manage to get some precise weather forecast and choose according to where the best is. this may require a bit of driving, though.
we have just came back from the alps (magic) which apart from 2 days rained the entire time.
we went back to font and did mornings and nights which seemed fine as at least we were climbing.
ill just add, it rained for 4 days before we decided to depart as we couldnt bare it any more.
below is a list of climbable problems in magic woods the rain: (in order of dryness)
bruno bloc - never ending story (part 2 more than part 1 as if the river is high then it gets badly sprayed.)
fight club - 7c
sofa surfer 8a - very good line which stays relatively dry, might be slightly moist on the higher holds if its heavy rain
down under 7c- right next to sofa surfer, an over hanging bloc sheltered from the rain but does drip if waterlobbed
roof of darkness is normally dry apart from the lip (top out) when it rains.
practice of the wild is also worth checking
if its not as heavy rain, then these problems could be on:
Blown away - 7b
supernova - 7c - also on the bruno bloc
pirranah might dry if the sun is on it ( if your lucky :[ )
this is just from what we found and tried after endless hours sitting playing shit head in the hut waiting for the rain to stop.
in the end it was that bad rain that we had to retreat back to font. but magic is defionatly one of the best places ive been. even if the walk ins are slightly sketchy in the rain as i found out on the first day as i fell off the path.
