Water Temperature in Saltwater: 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

Saltwater sits near Green Cape on the Far South Coast of New South Wales, right where the Tasman Sea meets a rugged, windswept shoreline. Water temperatures here reflect the cooler southern conditions and the exposed ocean setting. In summer, the sea usually warms to around 19–22 °C, which feels refreshing rather than warm but is still comfortable for swimming on sunny days. Autumn often stays mild, with temperatures commonly between 17–20 °C, while spring is cooler at roughly 15–18 °C as the ocean slowly warms after winter. During winter, water temperatures typically drop to about 13–15 °C, which can feel very cold without a wetsuit and generally limits swimming to short, bracing dips.
