Annual Water Temperature Trend

Darwin sits on the Timor Sea and has a fully tropical marine climate, which means the water is warm all year round. Sea temperatures stay high regardless of season. During the wet season and build-up, roughly from November to April, the water typically ranges between 28–31°C, often feeling very warm and sometimes almost bath-like. In the dry season, from May to October, temperatures ease slightly but remain comfortable, usually around 25–27°C. Even at their coolest, Darwin’s sea temperatures are warmer than summer water in most southern parts of Australia.
