Annual Water Temperature Trend

Lady Bay Beach is a small, secluded cove on Sydney’s eastern coastline, sitting just inside the harbour entrance with the Tasman Sea close by. Water temperatures here follow the usual Sydney north coast pattern but can feel a touch steadier thanks to the sheltered setting. In summer, the water typically sits around 22–26 °C, which feels comfortable for longer swims and relaxed dips. Autumn brings a gradual cool-down to roughly 20–23 °C. Winter is cooler but still swimmable for many, with temperatures generally between 16–20 °C, while spring sees a steady rise from about 18 °C into the low twenties as air temperatures improve and conditions settle.
