*** Forecast - Our water temperature forecast

Actual near-shore water temperatures in Yallingup 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.

Swimming Conditions

Swimming at Yallingup is allowed and popular, particularly in the lagoon area. The natural reef provides shelter from swell, often creating calm, clear water that suits families and relaxed swimmers during summer. These conditions make longer swims comfortable without wetsuits for most people. Outside the lagoon, the coastline is more exposed, with stronger waves and currents that are better suited to experienced ocean swimmers. In spring and autumn, shorter swims are common, while winter swimming tends to attract locals used to cooler water or those wearing thermal gear. Overall, Yallingup offers some of the best all-round swimming in the Margaret River area, combining cool, clean water with both sheltered and open-ocean options depending on conditions.
