*** Forecast - Our water temperature forecast

Actual near-shore water temperatures in Budgewoi 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 popular around Budgewoi, with both ocean and sheltered options depending on conditions. The ocean beach faces the open Tasman Sea, so surf, currents, and rips can be present, particularly after strong swell, making some days better suited to confident swimmers. On calmer days, the water is clean and refreshing, with easy access from the sand. Many locals also choose nearby lake or channel areas when they want gentler conditions, as these spots often feel warmer and more relaxed. With limited patrols, checking conditions and choosing the right spot for the day is key to enjoying safe swimming in Budgewoi.
