Annual Water Temperature Trend

Arrawarra sits on the far north coast of New South Wales, where a quiet creek meets the Tasman Sea under a warm subtropical climate. Water temperatures here are generally comfortable for swimming through most of the year. In summer, the ocean typically warms to around 25–27 °C, while the creek often feels just as warm or slightly warmer on still days. Autumn usually remains pleasant, with temperatures holding between 23–25 °C as conditions settle. Spring starts cooler at roughly 21–23 °C before steadily warming toward summer. Winter is the coolest period, but even then water temperatures usually sit around 18–21 °C, which many locals still find suitable for a swim on sunny days.
