⚠️ This is cool water that may feel brisk on entry. Swimming is usually limited to short sessions, and prolonged stays can become uncomfortable without thermal protection. Many swimmers choose a wetsuit, especially for surfing or open-water swimming.

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.
