In reply to samben6:
Not much to be honest. I think you'd be best off at Sea Walls in Avon Gorge, which at least is quick drying. The micro routes on choice wall are worthwhile and some can be highballed, the Arete just to the left is a good and techy 7A, and there's a few other bits and bobs. The new quarry traverse is also just round the corner.
Most of the actual bouldering is in the woods and sandstone, so won't dry fast - but you might be ok if we get a sustained dry spell.
