Chris? Nope - definately Rich Mate!!
Oxwich is normally fairly/very flat as it's nice and sheltered. Only really works if the wind is blowing in just the right direction. Ideally you need a southerly with a bit of Easterly, too much south and the wind is blocked off by the headland on your right as you look out to sea. (although you can walk further down the beach towards 3 cliffs if the direction marginal) - I love it because you can park right next to the beach and I'm a lazy bugger!
