In reply to purple sue:
It won't be cold trad climbing in the sun and no wind tomorrow at swanage, I'll be in my t shirt. Swanage main cliffs reputably don't seep much atall and I've been alot in the last few months and the only issue I've had is on overcast low wind high humidity days when it rained overnight (and only once has that been a big problem).
Hedbury is quite quick drying and was bone dry (apart from the stream) on boxing day. I can't comment when it will be dry enough tomorrow.
