*** Forecast - Our water temperature forecast

Actual near-shore water temperatures in Werri 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.

Annual Water Temperature Trend

Werri Beach stretches along the Illawarra coast facing the Tasman Sea, and its water temperatures reflect the open-ocean setting. In summer, the sea here typically sits between about 21–24 °C, making conditions comfortable for swimming and longer sessions in the water. Autumn often remains mild, with temperatures around 19–22 °C, while spring is cooler at roughly 17–20 °C as the ocean gradually warms after winter. During winter, water temperatures usually drop to about 16–18 °C, which can feel cold without a wetsuit, particularly on windy days, but is still manageable for short swims.

Swimming Conditions

Swimming at Werri Beach is allowed, though conditions are best suited to confident swimmers due to the beach’s exposure to Tasman Sea swells. Waves and currents are common, and water movement can be strong, especially after weather changes. On calmer summer days, swimming can be enjoyable and refreshing, while in cooler months many people prefer brief dips or wearing wetsuits. There are no sheltered bays here, so ocean awareness is important at all times. Overall, Werri Beach offers clean water and seasonal temperatures typical of the open coast, with swimming possible when conditions are favourable and approached with care.
