The face of the Harvey Oswald boulder stays dry in the rain and the top is mega juggy, so you might be able to get away with stuff there. Carreg Hylldrem stays dry in the rain and the seepage isn't too bad. Manor Crag dries very quickly and often has better weather than the mountains. The Orme area in general might not be a bad shout.
If you're there for a week and don't need to be climbing all day every day there will likely be some breaks in the weather for quick drying stuff to come into ok condition. The crag table in the start of the newest guide might be very useful to figure out where suits a given day best.
