*** Forecast - Our water temperature forecast
Actual near-shore water temperatures in Warriewood 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 Warriewood, particularly along the long stretch of sandy beach that runs north–south. As an open-ocean beach, conditions can change from day to day depending on swell, wind, and tides, and rips can form, especially after periods of stronger surf. Parts of the beach are often patrolled during peak seasons, providing safer swimming areas when flags are in place. On calmer days, the water is clean and refreshing, with straightforward access from the sand. Confident swimmers enjoy the classic surf-beach feel, while families and casual swimmers tend to stick between the flags or choose lighter swell days for a safer, more relaxed swim.
