Annual Water Temperature Trend

Newport, on Sydney’s Northern Beaches, sits right on the edge of the Tasman Sea and experiences water temperatures that make ocean swimming appealing for much of the year. In summer, the sea is at its warmest, usually around 22–26 °C, which feels comfortable for longer swims and regular dips. Autumn brings a gradual cool-down to roughly 20–23 °C, still pleasant for most swimmers. Winter is cooler but far from extreme, with water temperatures generally between 16–20 °C, while spring sees a steady warm-up from about 18 °C into the low twenties as air temperatures rise and conditions become more settled.
