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.
Bacterial levels are highly susceptible to storm runoff. Heavy rainfall in the local catchment is likely to trigger storm overflows and agricultural runoff, rendering the water temporarily unsafe.
Tested weekly by the Environment Agency England for bacteria levels (E. coli & Intestinal Enterococci) between May and September.
Monitored as a transitional or estuarine bathing water. Estuarine sites experience a mix of tidal ocean flushing and river discharge, causing fluctuating salinity and water quality.
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 1990. This designation mandates regular public health monitoring.
Governed under local district sanitation and environmental safety regulations in the Gwynedd area.
