Annual Water Temperature Trend

Warrain Beach is a quiet stretch of coastline on the South Coast of New South Wales, directly exposed to the Tasman Sea, and its water temperatures reflect that open-ocean setting. In summer, the sea generally warms to around 21–24 °C, making conditions comfortable for swimming and cooling off on hot days. Autumn often stays fairly mild, with water temperatures commonly sitting between 19–22 °C, while spring is cooler at roughly 17–20 °C as the ocean slowly recovers from winter. During winter, temperatures usually drop to about 16–18 °C, which can feel sharp without a wetsuit, especially with southerly winds adding an extra chill.
