Important! Tide times are for the nearest measurement point (Mumbles) and may not be accurate for this beach. You should not rely on these times for anything other than a broad indication of when the tide will be at its highest or lowest.

In particular, these tide times are not suitable for navigational use.

Accurate tide forecasts require complex calculations and detailed local information. If you intend to engage in any activity for which tidal information is important for safety reasons (including sailing, powerboating, diving, and surfing) then you should obtain professional data.

Tidal predictions are © Crown Copyright and/or database rights. Reproduced by permission of the Controller of Her Majesty's Stationery Office and the UK Hydrographic Office (www.ukho.gov.uk).
