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.
