*** Forecast - Our water temperature forecast
Actual near-shore water temperatures in Ethel 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.

Swimming Conditions
Swimming at Ethel Beach is allowed, but it’s best suited to confident swimmers who understand local conditions. Unlike the sheltered harbour at Flying Fish Cove, Ethel Beach is more exposed to ocean swell, and waves, currents, and surge can be present even on calm-looking days. On settled weather days, the warm, clear water is excellent for short swims and snorkelling close to shore, with no need for wetsuits. However, changing tides and sudden swell mean swimming is not always recommended, and conditions should be checked carefully before entering the water. Overall, Ethel Beach offers appealing warm-water swimming in a wild tropical setting, where enjoyment depends on calm conditions and sensible caution rather than water temperature.
