Annual Water Temperature Trend

Port Victoria sits on the western side of the Yorke Peninsula, looking out over the relatively sheltered waters of Spencer Gulf, and this location gives it milder water temperatures than the open southern ocean. In summer, the sea is at its warmest, usually around 20–24°C, which feels comfortable and inviting for swimming on hot days. Autumn brings a gradual cooling to roughly 18–21°C, while winter is cooler but still manageable, often around 13–15°C. Spring sees a steady warm-up, with water temperatures commonly sitting between 16–19°C, helped by sunshine and calmer gulf conditions.
