Annual Water Temperature Trend

Peaceful Bay sits south-west of Denmark in a naturally protected cove, offering a calmer feel than many beaches along the Great Australian Bight. Water temperatures here follow the cool pattern of the far south coast but are often a touch more comfortable due to the sheltered setting. In summer, from December to February, the sea typically ranges between 18–21°C, which feels pleasant on warm, sunny days. Autumn cools gradually to around 16–19°C, while winter is colder and bracing, usually about 13–15°C. Spring brings a steady warm-up again, generally 15–17°C, though early-season swims can still feel fresh.
