Annual Water Temperature Trend

Nanarup Beach lies just east of Esperance and faces straight into the open sweep of the Great Australian Bight, giving it a raw and energetic coastal feel. Water temperatures here follow the familiar pattern of the far south coast. In summer, from December to February, the sea usually sits around 18–22°C, which can feel quite comfortable on warm days. Autumn sees a gradual cooling to about 16–19°C, while winter is distinctly cold, most often between 13–15°C. Spring brings a slow rise again, generally 15–17°C, though frequent southerly winds can make the water feel cooler than the numbers suggest.
