Annual Water Temperature Trend

Tathra sits on the Far South Coast of New South Wales, facing the open Tasman Sea, and its water temperatures reflect the cooler end of the state’s coastline. In summer, the ocean usually warms to around 20–23 °C, which feels refreshing and comfortable for swimming on warm days. Autumn often stays mild, with temperatures commonly between 18–21 °C, while spring is cooler at roughly 16–19 °C as the sea gradually warms after winter. During winter, water temperatures typically drop to about 14–16 °C, which can feel quite cold without a wetsuit and usually limits swimming to short, bracing dips.
