Annual Water Temperature Trend

Sandon is a small coastal settlement on the far north coast of New South Wales, where the Sandon River meets the Coral Sea. The area enjoys a warm subtropical climate, and water temperatures are generally comfortable for swimming through much of the year. In summer, both the river and nearby ocean typically reach around 25–27 °C, making the water feel warm and inviting. Autumn often remains mild, with temperatures commonly 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.
