Annual Water Temperature Trend

Wallaga Lake is a small coastal town on the Far South Coast of New South Wales, set beside the sheltered waters of the lake and close to the Tasman Sea. Water temperatures here follow the cooler southern pattern but are slightly moderated by the calm lake environment. In summer, lake and nearby coastal waters usually sit around 20–23 °C, which feels comfortable for swimming, especially on still, sunny days. Autumn often remains mild, with temperatures commonly between 18–21 °C, while spring is cooler at roughly 16–19 °C as the water gradually warms after winter. During winter, water temperatures typically drop to about 14–16 °C, which can feel cold without a wetsuit but is still manageable for short dips.
