It’s important to note that these swimming tips and recommendations apply only in settled weather. When air temperatures drop below 20°C — and sometimes even below 25°C — swimming can feel uncomfortable, even when water temperatures are relatively high.

*** Forecast - Our water temperature forecast
Actual near-shore water temperatures in Penguin 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 Penguin is allowed and is fairly popular, especially at the town’s main beach and nearby sheltered spots. Compared with more exposed Bass Strait beaches, local conditions are often gentler, with smaller waves during settled weather, making short swims and casual dips more comfortable. Even so, the water temperature means most people keep swims brief, and wetsuits are commonly used outside peak summer. After windy days, swell and currents can pick up, so it’s important to be mindful of conditions. Overall, Penguin offers good cold-water swimming by Tasmanian standards, best enjoyed in summer and during calm periods close to shore.
