Annual Water Temperature Trend

Mylestom sits at the mouth of the Bellinger River on the mid–north coast of New South Wales, where calm estuary waters meet the Tasman Sea. The local climate keeps water temperatures comfortable for swimming through much of the year. In summer, the river and nearby ocean typically warm to around 24–26 °C, making conditions ideal for easy, relaxed swims. Autumn often remains mild, with temperatures usually sitting between 22–24 °C as the weather settles. Spring starts cooler at roughly 20–22 °C before steadily warming toward summer. Winter is the coolest season, but water temperatures generally stay around 18–20 °C, which many locals still find fine for a dip on clear, sunny days.
