The cloud base could be down near crag level, so if not raining per se it'll still be damp. It is due to lift though, and with the north westerly wind it could dry up nicely!
Next time look at the rain radar as this shows if it is actually raining and if the radar is animated you can predict the next few hours even if showers are around. Rain Today is one of the best... I check it every time before I climb.
