Annual Water Temperature Trend

Ocean Beach lies just south of Denmark and faces directly into the Great Australian Bight, giving it a classic open-ocean feel with long sands and constant movement in the water. Sea temperatures here are cool and strongly seasonal. In summer, from December to February, the water usually sits around 18–21°C, which can feel quite pleasant on warm, still days. Autumn brings a gradual drop to about 16–19°C, while winter is cold and bracing, most often around 13–15°C. Spring sees a slow warm-up again, typically 15–17°C, though frequent southerly winds can keep the water feeling sharp.
