Annual Water Temperature Trend

Bremer Bay sits on a rugged yet surprisingly varied stretch of the far south coast, where sheltered bays contrast with open ocean beaches along the Great Australian Bight. Water temperatures here stay on the cool side year-round. In summer, from December to February, the sea typically ranges between 18–21°C, feeling pleasant on calm, sunny days. Autumn brings a gradual drop to around 16–19°C, while winter is distinctly cold, most often sitting at 13–15°C. Spring sees a slow warm-up again, usually around 15–17°C, though brisk winds can keep the water feeling cooler than expected.
