Picks up more swell than any of the other Anglesey beaches - lefts and rights - mellow wave, not too steep - rips are not too bad - probably the best spot on Anglesey!
Not a very good wave, slow and never hollow. Good for beginners as it can't handle a swell bigger than a 4 or 5 ft. However on rare days a good shorey can be surfed at high tide breaking heavy and fast in shallow water. Also if the swell is bigger than a proper 2ft then venture south and you may come across a decent reef, and on occasions a perfect right breaking on sand.
My local break, there are no crowds and can get big and washed out, but you must watch out for the canoeists (no regard for surfers). Not ideal but best we've got.
Rhosneigr is arguably the best spot on Anglesey, the waves are usually half a foot smaller than in Hellsmouth. Breaking over sandbanks the surf here is safe and never gets bigger than 6ft without being storm surf. The wave is a right, rarely barrels
