Hi Pete
Here's a local website address;

On the Map we raced from Mumbles (bottom right) to Oxwich (bottom middle) if you click on each of the Beach names you should find some photo's. Between Mumbles Head and Langland there are the Mixon sandbanks and the swell is really thrown up. Off Pwll Du Head you have some overfalls which can be interesting and Oxwich Bay is a Catamaran sailors Heaven, clean prevailing winds and super flat sea.
