*** Forecast - Our water temperature forecast
Actual near-shore water temperatures in Crowdy Bay 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 enjoyed around Crowdy Bay, but conditions are very much dictated by the open ocean. The long, exposed beaches can experience rolling surf and rips, particularly after periods of 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 and plenty of space to spread out. The natural setting means patrols are limited, so choosing suitable conditions is important. With the right weather and swell, Crowdy Bay offers rewarding ocean swimming in a quiet, unspoilt coastal environment.
