In reply to Ehmarra:
I've only actually climbed there after a dry day days in the winter, when there was some seepage, but plenty that was dry. I have stopped there several times, when paddling in the spring/summer, usually on a sunny day, but not sure what the previous days were like, the rock always looked inviting. I think this means you will be OK, but if someone else says I'm talking rubbish they are probably correct. At least the rain has stopped now.
