Annual Water Temperature Trend

Casuarina Beach stretches along the northern edge of Darwin, facing the Timor Sea within the Casuarina Coastal Reserve. Water temperatures here are consistently warm due to the tropical climate. During the build-up and wet season, roughly from November to April, sea temperatures usually sit between 28–31°C, often feeling very warm and humid. In the dry season, from May to October, the water cools only slightly, generally ranging between 25–27°C, which is still comfortably warm by any standard. There is very little seasonal variation compared with southern Australian beaches.
