Annual Water Temperature Trend

Kingscote sits on the eastern side of Kangaroo Island, facing the relatively sheltered waters of Spencer Gulf, which makes a noticeable difference to water conditions compared with the island’s open-ocean beaches. Sea temperatures here follow a clear seasonal pattern. In summer, from December to February, the water usually ranges between 18–21°C, often feeling a touch warmer than the south coast on calm days. Autumn cools gradually to around 16–19°C, while winter is the coldest period, commonly 13–15°C. Spring brings a steady rise again, with temperatures generally sitting between 15–17°C as daylight and air temperatures improve.
