*** Forecast - Our water temperature forecast
Actual near-shore water temperatures in Mandalay Beach can vary by several degrees from the values shown, particularly after heavy rain, strong southerlies, or prolonged windy conditions. Certain wind patterns can trigger upwelling, where cooler, deeper water is pushed to the surface and replaces the warmer top layer, leading to noticeable short-term changes in water temperature.
Our water temperature forecast is produced using a proprietary mathematical model that combines real-time measurements with long-term historical patterns, local weather conditions, wind strength and direction, and air temperature specific to each coastal region. To improve accuracy, we cross-check data from nearby locations and use multiple sources, including offshore buoys, satellite-based sea surface maps, and observations provided by local authorities.

Monthly Water Temp Ranges
Annual Water Temperature Trend
Mandalay Beach sits just south-east of Denmark at the mouth of the Wilson Inlet, where freshwater influence and the open edge of the Great Australian Bight shape local conditions. Water temperatures here are cool but slightly moderated compared with fully exposed ocean beaches. In summer, from December to February, the sea usually ranges between 18–21°C, often feeling comfortable on sunny, low-wind days. Autumn sees a gradual drop to around 16–19°C, while winter is colder and brisk, typically sitting at 13–15°C. Spring brings a slow warm-up again to about 15–17°C, though early-season swims can still feel sharp.

Swimming Conditions
Swimming at Mandalay Beach is allowed, but suitability depends on conditions and location. Near the inlet mouth and sheltered sections, the water is often calmer, making swimming more approachable in summer, especially for confident swimmers. These areas tend to have gentler waves and easier entry than the fully open beach. Further along the shoreline, exposure to swell and currents increases, and swimming becomes more challenging. In summer, many people swim without wetsuits, while spring and autumn are better for shorter dips. Winter swimming is usually brief or done with thermal gear. Overall, Mandalay Beach offers varied swimming opportunities, combining cool, clean southern water with both sheltered and open-ocean conditions for those who choose their spot carefully.
