*** Forecast - Our water temperature forecast
Actual near-shore water temperatures in Lady Bay 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 Overview by Month
Monthly Water Temp Ranges
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.
