Water Temperature in Aspendale: Daily Trends, Historical Records, and Forecast

❌ Water at this temperature feels cold and is generally suitable only for brief immersion. Swimming without a wetsuit can quickly become uncomfortable, and exposure time is usually short. These conditions are mainly suitable for experienced swimmers or those using proper thermal gear.

It’s important to note that these swimming tips and recommendations apply only in settled weather. When air temperatures drop below 20°C — and sometimes even below 25°C — swimming can feel uncomfortable, even when water temperatures are relatively high.

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.
