*** Forecast - Our water temperature forecast
Actual near-shore water temperatures in Macquarie Heads 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.

Monthly Water Temp Ranges
Annual Water Temperature Trend
Macquarie Heads sits at the entrance to Macquarie Harbour on Tasmania’s remote west coast, where sheltered harbour waters meet the open Indian Ocean. This setting creates a mix of conditions, but temperatures stay cold year-round. In summer, from December to February, water temperatures generally range from about 14–16 °C in the ocean, with slightly milder conditions inside the harbour on calm days. Autumn sees a gradual drop to around 13–15 °C, while winter is the coldest period, typically about 10–12 °C. Spring brings a slow and modest warm-up, with water temperatures usually sitting between 11–13 °C, often influenced by wind and changing weather.

Swimming Conditions
Swimming at Macquarie Heads is allowed, but it’s not a typical swimming destination. The open coastline is exposed to strong Indian Ocean swells, cold water, and powerful currents, making ocean swimming suitable only for experienced swimmers and only during rare calm conditions. Inside Macquarie Harbour, the water is more sheltered, with little wave action, which can make short swims possible in summer. Even there, cold temperatures mean swims are usually brief, and wetsuits are common. Overall, Macquarie Heads offers limited but possible cold-water swimming, with safety heavily dependent on choosing sheltered spots and paying close attention to weather and local conditions.
