*** Forecast - Our water temperature forecast

Actual near-shore water temperatures in Patonga 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 is allowed and very popular at Patonga, largely because the beach is well protected from strong ocean swell. The calm waters mean there are usually no breaking waves and very few strong currents, making it suitable for families, casual swimmers, and anyone who prefers a relaxed swim. Entry from the sandy shoreline is easy, and the water is generally clean and clear. While boat traffic can be present farther out in the bay, the swimming areas close to shore are typically safe on calm days. Thanks to its sheltered position and pleasant seasonal water temperatures, Patonga offers reliable and easy swimming for much of the year.
