Llanddona sits in Isle of Anglesey, Wales as a designated coastal bathing water featuring a sandy shoreline. Bathing water monitoring across the season yields an official annual rating of Excellent for the site. Formally designated in 1997, it remains an important coastal destination for residents and visitors alike.
The shoreline consists primarily of sand. Sediment type dictates underfoot comfort, wave energy absorption, and the water's clarity when currents stir up the seabed.
Water quality is classified as excellent, meeting the highest cleanliness standards. Bacterial counts (E. coli & Intestinal Enterococci) are consistently low, posing negligible health risks.
This bathing water is generally resilient and has a low risk of quality degradation after heavy summer storm events.
Tested weekly by the Environment Agency England for bacteria levels (E. coli & Intestinal Enterococci) between May and September.
Monitored as a coastal beach. Coastal beaches are subject to tidal flows and marine dilution, whereas inland lakes/rivers suffer from low water circulation, meaning bacteria can linger longer.
Unknown is the regional utility responsible for waste water treatment, sewage infrastructure, and storm overflow management in this catchment area.
Officially designated as a protected bathing water site in 1997. This designation mandates regular public health monitoring.
