Annual Water Temperature Trend

The Entrance, on New South Wales’ Central Coast, sits where Tuggerah Lake meets the Tasman Sea, giving visitors a mix of sheltered estuary waters and open-ocean conditions. Sea temperatures follow a clear seasonal pattern: summer water generally ranges from about 22–26°C, offering comfortably warm bathing; autumn cools to roughly 19–24°C as the ocean begins to lose heat; winter sees the coldest conditions, commonly around 16–19°C; and spring warms again to near 17–22°C, with temperatures varying day to day. Shallow areas of the lake and river channels tend to warm faster and are often a degree or two higher than exposed ocean water, while deeper channels and surf zones can feel noticeably cooler. Wind, tides and swell size also influence how warm the water feels on any given day.
