Annual Water Temperature Trend

Mullaway sits on the far north coast of New South Wales, facing the Tasman Sea and shaped by 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, making conditions inviting for long swims and time spent in the water. Autumn often holds onto that warmth, with sea temperatures commonly between 23–25 °C as weather patterns settle. Spring begins cooler at roughly 21–23 °C before steadily warming toward summer. Winter is the coolest season, but even then the water usually sits around 19–21 °C, which many locals still find suitable for a swim on clear, sunny days.
