Annual Water Temperature Trend

Marlo sits where the Snowy River meets the Bass Strait on the East Coast of Victoria, and water temperatures here reflect the cooler southern ocean conditions. In summer, the sea and river mouth usually sit around 18–22 °C, which feels refreshing but comfortable for swimming on warm 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 generally suits only short dips or swimmers wearing wetsuits.
