Water Temperature in Fannie Bay: Daily Trends, Historical Records, and Forecast

✅ Water at this temperature is very warm and feels almost tropical. Swimming is comfortable for most people, even for long periods, with no sensation of cold. These conditions are ideal for relaxed swimming, floating, and water play, especially for families and casual swimmers. However, during very hot weather, the water may feel less refreshing, and short breaks are often welcome.

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

Fannie Bay sits just west of central Darwin, overlooking the Timor Sea with a broad foreshore and a strong tropical feel. Water temperatures here stay warm all year thanks to the northern climate. During the build-up and wet season, roughly from November to April, the sea usually ranges between 28–31°C, often feeling very warm and humid. In the dry season, from May to October, temperatures ease slightly but remain high, typically around 25–27°C. Even in the coolest months, the water is warmer than summer sea temperatures in most of southern Australia.
