From my limited experience it's generally hit and miss! Oxwich is the only beach sheltered on a W/SW wind, but I have rarely fished there. Might go this weekend and see how it is and I'll let you know! Other than that, the slightest wind or swell usually messes things up everywhere else.
Wind looks as if it's picking up this weekend along with the swell so even with the small tides it could be a right off! I've seen videos of mewslade and the water is crystal clear! Maybe because theres generally not much sand that could be another place to check out when everywhere else is shite. Have you had much experience around the Gower?
