Annual Water Temperature Trend

Sapphire Beach sits just north of Coffs Harbour on the far north coast of New South Wales, facing the Tasman Sea and influenced by a warm subtropical climate. Water temperatures here are comfortable for swimming across much of the year. During summer, the ocean typically warms to around 25–27 °C, making the water feel inviting for long swims and cooling off on hot days. Autumn often stays pleasant, with sea temperatures commonly between 23–25 °C as conditions become more settled. 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 swimmable on clear, sunny days.
