Annual Water Temperature Trend

South Wall Ballina sits at the southern entrance of the Richmond River on the far north coast of New South Wales, where river waters meet the Coral Sea. Water temperatures here are shaped by the region’s warm subtropical climate and are generally comfortable for swimming through much of the year. In summer, the water typically reaches around 25–27 °C, both in the river mouth and nearby ocean, making conditions pleasant for longer swims. Autumn often stays warm, with temperatures commonly between 23–25 °C as the weather settles. Spring begins cooler at roughly 21–23 °C before gradually warming. Winter is the coolest season, but even then water temperatures usually sit around 19–21 °C, which many locals still find fine on sunny days.
