Annual Water Temperature Trend

Oberon Bay lies within Wilsons Promontory on the East Coast of Victoria, facing the open waters of the Bass Strait, and water temperatures here are shaped by the cool southern ocean. In summer, the sea generally warms to around 18–22 °C, which feels refreshing rather than warm but is still comfortable for swimming on sunny days. Autumn often stays mild, with temperatures commonly between 16–20 °C, while spring is cooler at roughly 14–18 °C as the water gradually warms after winter. During winter, water temperatures typically drop to about 11–14 °C, which is cold and usually limits swimming to short dips or those wearing wetsuits.
