Annual Water Temperature Trend

Christmas Beach is a lesser-known stretch of coastline on the far north coast of New South Wales, facing the Coral Sea and shaped by a warm subtropical climate. Water temperatures here are generally comfortable for swimming through much of the year. In summer, the ocean typically warms to around 25–27 °C, creating pleasant conditions for extended swims. Autumn often holds onto that warmth, with temperatures commonly between 23–25 °C as the sea settles between weather systems. Spring starts a little cooler at roughly 21–23 °C before steadily warming toward summer. Winter brings the coolest water, but even then temperatures usually sit around 19–21 °C, which many locals still find suitable on clear, sunny days.
