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.
