❌ 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

George Town sits at the mouth of the Tamar River on Tasmania’s north coast, where river and sea meet before opening into the Bass Strait. This mix influences local water temperatures, which remain cool across the year. In summer, from December to February, sea temperatures usually reach around 15–17 °C, while the river can feel slightly milder on calm, sunny days. Autumn sees water temperatures ease back to about 13–15 °C, winter is coldest at roughly 11–12 °C, and spring brings a gradual rise to around 12–14 °C as conditions become more settled.
