*** Forecast - Our water temperature forecast

Actual near-shore water temperatures in Contos 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.

Annual Water Temperature Trend

Contos Beach sits along the southern stretch of the Margaret River coastline, where the Indian Ocean rolls in with steady energy and a distinctly wild feel. Water temperatures here are cool but consistent, shaped by southern ocean currents. In summer, from December to February, the sea generally ranges between 19–22°C, which can feel quite comfortable on warm, sunny days. Autumn brings a gradual cooling to around 17–20°C, while winter is colder and more bracing, typically sitting between 14–16°C. Spring sees temperatures slowly rise again to about 16–18°C, though strong coastal winds can make the water feel cooler than the numbers suggest.

Swimming Conditions

Swimming at Contos Beach is allowed, but it’s better suited to confident swimmers who are comfortable in open-ocean conditions. The beach is exposed, with regular swell and currents that can be strong, particularly outside calm summer periods. On settled summer days, swimming can be refreshing and enjoyable, especially close to shore, but conditions can change quickly. Many people prefer shorter swims, and wetsuits are common even in warmer months. Spring and autumn usually suit brief dips, while winter swimming is mainly for experienced locals or those wearing thermal gear. Overall, Contos Beach offers a raw, natural swimming experience, combining cool Indian Ocean water with an energetic coastal setting rather than sheltered, relaxed bathing.
