Annual Water Temperature Trend

Strahan sits on Tasmania’s rugged west coast beside the sheltered waters of Macquarie Harbour, with the Indian Ocean just beyond the harbour entrance. Water temperatures here are cold throughout the year, though the harbour tends to be slightly milder than the open coast. In summer, from December to February, water temperatures usually range around 14–16 °C, occasionally feeling a touch warmer inside the harbour on calm, sunny days. Autumn brings a gradual cooling to about 13–15 °C, while winter is the coldest period, commonly around 10–12 °C. Spring sees a slow warm-up, with temperatures generally between 11–13 °C as daylight increases.
