*** Forecast - Our water temperature forecast
Actual near-shore water temperatures in Kingston 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 in Kingston is allowed and is enjoyed mainly in sheltered spots rather than along fully exposed coastline. Kingston’s reef-protected areas and calmer bays can offer relatively gentle conditions, especially during settled weather, making them suitable for relaxed swims and cooling dips. Even in winter, the water temperature remains mild compared to mainland southern Australia, so wetsuits are optional rather than essential. That said, Norfolk Island’s coast can experience strong swell and surge, and entry points are often over rock or reef, so swimmers need to choose locations carefully and watch conditions. Overall, Kingston offers pleasant year-round swimming by island standards, with the best experiences coming during calm summer days in protected areas where the ocean is at its most approachable.
