Annual Water Temperature Trend

Aspendale sits on the eastern side of Port Phillip Bay in Melbourne’s south-east, and its water temperatures reflect the sheltered nature of the bay rather than the full force of the Bass Strait. In summer, the water usually warms to around 19–23 °C, which feels comfortable for swimming and cooling off during hot spells. Autumn often stays mild, with temperatures commonly between 17–21 °C, while spring is cooler at roughly 15–19 °C as the bay slowly warms after winter. During winter, water temperatures typically drop to about 13–15 °C, which feels cold but is still manageable for short swims on calm, sunny days.
