*** Forecast - Our water temperature forecast

Actual near-shore water temperatures in South West Rocks 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.

Sheltered spots, such as those protected by headlands, often have calmer water and fewer rips, making them suitable for families and casual swimmers. Open beaches offer a more traditional ocean swim, with clean water and rolling surf, though conditions can change with swell and weather. Some areas are patrolled during peak periods, adding to safety. This variety means swimmers can usually find a suitable spot year-round by matching their choice of beach to the day’s conditions.
