Anglesey · open water conditions information
Aberffraw Bay (Traeth Mawr) is a coastal location in Anglesey, one of 35 Anglesey spots covered by NippyIndex.
The shore faces broadly south-west, so it is most open to wind and swell arriving from the south-west.
As a tidal location, its tide predictions are referenced to the nearest tidal station, Porth Trecastell.
NippyIndex draws on published marine and weather data (sea state, wave information and water temperature) and UKHO tidal predictions.
