Annual Water Temperature Trend

Balmoral sits on Sydney’s lower north shore, tucked inside Middle Harbour with the Tasman Sea just beyond the heads. Thanks to its sheltered position, water temperatures here are generally a little steadier than at open surf beaches. In summer, the water usually ranges from about 22–26 °C, often feeling pleasantly warm on calm, sunny days. Autumn brings a gentle cool-down to roughly 20–23 °C. Winter is cooler but still comfortable for many swimmers, with temperatures typically between 16–20 °C, while spring sees a gradual warm-up from around 18 °C into the low twenties as air temperatures rise.
