Annual Water Temperature Trend

Eucla sits right on the edge of the Nullarbor, facing the vast sweep of the Great Australian Bight, and the water here reflects that exposed, southern-ocean setting. Sea temperatures stay cool throughout the year. In summer, from December to February, the water generally ranges between 17–20°C, sometimes feeling warmer on calm, sunny days. Autumn brings a gradual drop to around 15–18°C, while winter is cold, often sitting near 12–14°C. Spring marks a slow recovery, with temperatures usually in the 14–16°C range, though the water can still feel sharp due to wind and swell.
