*** Forecast - Our water temperature forecast

Actual near-shore water temperatures in Blacksmiths Beach can vary by several degrees from the values shown, particularly after heavy rain, strong southerlies, or prolonged windy conditions. Certain wind patterns can trigger upwelling, where cooler, deeper water is pushed to the surface and replaces the warmer top layer, leading to noticeable short-term changes in water temperature.

Our water temperature forecast is produced using a proprietary mathematical model that combines real-time measurements with long-term historical patterns, local weather conditions, wind strength and direction, and air temperature specific to each coastal region. To improve accuracy, we cross-check data from nearby locations and use multiple sources, including offshore buoys, satellite-based sea surface maps, and observations provided by local authorities.

Swimming Conditions

Swimming is allowed and popular at Blacksmiths Beach, especially along the wide stretch of sand near the Swansea Channel. The beach is open to the ocean, so surf and rips can be present, particularly after periods of strong swell, and conditions vary from day to day.
