*** Forecast - Our water temperature forecast
Actual near-shore water temperatures in Green Cape 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 Overview by Month
Monthly Water Temp Ranges
Annual Water Temperature Trend
Green Cape marks one of the most exposed sections of coastline on the Far South Coast of New South Wales, where the Tasman Sea meets rugged headlands and powerful ocean conditions. Water temperatures here are among the coolest in the state. In summer, the sea typically reaches around 19–22 °C, which feels refreshing but noticeably cooler than beaches further north. Autumn remains fairly mild, with temperatures usually between 17–20 °C, while spring is cooler again at roughly 15–18 °C as the ocean slowly warms after winter. During winter, water temperatures often fall to about 13–15 °C, making the water very cold without a wetsuit and limiting most swimming to brief, bracing dips.

Swimming Conditions
Swimming at Green Cape is allowed, but conditions are generally suitable only for experienced and confident ocean swimmers. The area is fully exposed to Tasman Sea swells, with strong waves, surge, and unpredictable currents common throughout the year. There are no sheltered beaches or bays, and conditions can change quickly with wind and weather. On rare calm summer days, swimming can be possible and very clear, but it requires good judgement and constant awareness of the ocean. In cooler months, most people avoid swimming altogether or use full wetsuits. Overall, Green Cape offers clean water, sharp seasonal temperature changes, and challenging swimming conditions in a wild and remote coastal environment.
