Bathing water

Page updated on: 22/09/2026

Natural Resources Wales (NRW) monitors water quality at the designated bathing waters at Pembrey and Pendine beaches, as well as the designated river bathing water at Llandeilo Swing Bridge.

Water quality sampling results are published by NRW throughout the bathing season. The information below shows the latest available water quality classification for each location and whether it meets the standards set out in the Bathing Water Directives (76/160/EEC and 2006/7/EC).

Water Quality Information

Please note: Water quality information displayed on this page is sourced directly from Natural Resources Wales (NRW). Whilst Carmarthenshire County Council aims to make the latest information available as quickly as possible, there may occasionally be a delay between NRW receiving and validating monitoring results and those results appearing on their website.

Where Carmarthenshire County Council receives water quality notifications directly from NRW before they are published online, we will display a summary of those updates below to help keep visitors informed.

Latest Updates from NRW

"There are currently no additional updates to report. Please refer to the water quality information table below for the latest published results."

Before You Enter the Water

Water quality can change rapidly, particularly following periods of heavy rainfall. A favourable water quality result reflects conditions at the time of sampling only and should not be regarded as a guarantee that conditions remain unchanged.

Bathers should:

  • Check the latest NRW bathing water profile before visiting.
  • Be aware of any pollution warnings, advice against bathing or abnormal situation notifications.
  • Consider recent weather conditions, particularly heavy rainfall, which can affect river and coastal water quality.
  • Make their own assessment of conditions before entering the water.

Important Information

Bathing water quality and water safety are not the same thing. A designated bathing water classification relates to water quality monitoring and does not indicate that a location is free from physical hazards or supervised by lifeguards. Visitors should always follow local safety advice, observe warning signage and take responsibility for their own safety.
