In reply to Andy2:
Crags north of St. Davids tend to be pretty shady and cold this time of year, but if the air temperatures are not so bad then crags like
No match for crag id:63 and
No match for crag id:65 have great routes in your grade range and may be dry.
The climbing on
No match for crag id:1265 itself catches more sun (especially in the morning) but the aspect may also mean you get some of the wind problems from the sandstone bays transferred, routes there are OK, slightly short and generally non tidal.
Starting a day at St. Davids head and heading across to Coetan or Trwyn Llwyd later (when they may catch a little oblique sun) can make for a good day.
Worth seeking out are
Barad (E1 5b) (E1 in CC Guide)
Twinkler (HVS 5a) (now given HVS) and
Act of God (VS 4c). More adventurous than the sandstone if you like that sort of thing.
Sandstone wise south of St. Davids
No match for crag id:2791 is positioned in a sheltered bay (as long as the wind isn't blowing right into the mouth of the inlet. It is tidal (though hanging belays are possible) routes there might be generally a little easy for your taste, but
Aries (VS 4b) is a gem.
