Sediment Type
Sand

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.

Annual Rating
Sufficient

Water complies with minimum legal safety limits. However, higher bacterial levels are occasionally recorded, indicating moderate vulnerability to runoff.

Rainfall Impact
High Risk

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.

Monitoring Authority
Environment Agency

Tested weekly by the Environment Agency England for bacteria levels (E. coli & Intestinal Enterococci) between May and September.

Water Body Type
Coastal Beach

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.

Sewerage Provider
Unknown

Unknown is the regional utility responsible for waste water treatment, sewage infrastructure, and storm overflow management in this catchment area.

Designated Year
2012

Officially designated as a protected bathing water site in 2012. This designation mandates regular public health monitoring.

County / District
Pembrokeshire

Governed under local district sanitation and environmental safety regulations in the Pembrokeshire area.
