Annual Water Temperature Trend

Canunda sits along a wild stretch of South Australia’s south-east coast, facing straight into the Great Australian Bight, and this exposure keeps water temperatures cool for most of the year. In summer, the ocean is at its warmest, usually around 17–20°C, which still feels brisk but can be refreshing on hot days. Autumn brings a gradual cooling to roughly 15–18°C, while winter is distinctly cold, often around 12–14°C. Spring warms slowly, with water temperatures commonly sitting between 13–16°C, and conditions can change quickly after strong southerly winds or swell.
