Annual Water Temperature Trend

Pyramid Rock sits on the rugged southern edge of Phillip Island, looking straight out over the Bass Strait, and water temperatures here reflect the cool, exposed nature of Victoria’s coastline. In summer, the ocean usually reaches around 18–22 °C, which feels refreshing rather than warm but is comfortable enough for swimming on sunny, settled days. Autumn often remains mild, with temperatures commonly between 16–20 °C, while spring is cooler at roughly 14–18 °C as the sea gradually warms after winter. During winter, water temperatures typically drop to about 11–14 °C, which is cold and generally limits swimming to short dips or those wearing wetsuits.
