In reply to Cake:
showers forecast throughout the morning along with the high winds following on from plenty of rain Friday day/night. I wouldn't be looking at abseil approach venues until at least the afternoon once the weather has possibly become more settled.
Your tide time is completely wrong too, see below. Although most of St Govan's East is non tidal it may not be in the heavy high midday seas. As mentioned above I have seen spray going over the tops of the cliffs there on windy days before, we managed on that occasion to climb at Triple Overhang, but it was a dry day.

10-Aug low is 07:42 GMT & 20:24 with high at 14:00 GMT - so pretty rubbish
Probably best if you must climb to try and go to places high above the sea as possible with an walk or easy scrambling descents/escape routes and be prepared to be disappointed.
