Annual Water Temperature Trend

Iluka Bluff Beach sits beneath the Iluka headland on the far north coast of New South Wales, facing the Coral Sea and influenced by a warm subtropical climate. Water temperatures here are generally comfortable for swimming across much of the year. In summer, the ocean typically warms to around 25–27 °C, making the water feel inviting for longer swims. Autumn often holds onto that warmth, with temperatures commonly between 23–25 °C and more settled conditions. Spring starts a little cooler at roughly 21–23 °C before steadily warming as summer approaches. Winter is the coolest period, but even then the sea usually sits around 19–21 °C, which many locals still find fine for a swim on clear, sunny days.
