Apparently there are some steel posts sticking out of the sand in the middle of the beach that weren't exposed before. Notice is aimed at surfers but ribbers also beware.
I got excited for a minute when I read about the exposed wreck - until I saw it said "steel posts". A few Spanish treasure ships have sunk in the bay and on the aptly named Spaniard rocks. Some of the cannons are in a garden in the village and you still get gold doubloons and silver dollars(pieces of eight) washed up from time to time.
