Annual Water Temperature Trend

Smiths Beach sits on Phillip Island’s southern coastline, facing the Bass Strait, and its water temperatures reflect the cooler conditions of Victoria’s exposed coast. In summer, the ocean generally warms to around 18–22 °C, which feels refreshing but comfortable for swimming on clear, sunny days. Autumn often stays mild, with water temperatures commonly between 16–20 °C, while spring is cooler at roughly 14–18 °C as the sea gradually warms after winter. During winter, temperatures typically fall to about 11–14 °C, which is quite cold and usually limits swimming to short dips or those wearing wetsuits.
