*** Forecast - Our water temperature forecast
Actual river water temperatures may vary by several degrees from the reported values, particularly after heavy rainfall or periods of changing weather. Rainfall, river flow rates, and runoff from cooler upstream areas can significantly affect water temperature, especially in flowing sections and shaded stretches. Air temperature and cloud cover also play an important role, with warm, sunny conditions helping rivers warm up more quickly. As a result, noticeable temperature differences can occur along the same river.
Our forecast is based on a proprietary mathematical model that takes into account real-time river temperature changes, historical data, seasonal patterns, river flow conditions, recent rainfall, and local air temperature. We also factor in broader weather conditions specific to each region of Australia to improve accuracy.

Location & Local Information
Parsley Bay Beach sits in Sydney’s eastern suburbs, tucked into a narrow harbour inlet with high bushy banks on either side. Thanks to this sheltered setting, water temperatures here tend to be steadier than at open ocean beaches. In summer, the harbour water usually sits around 22–26 °C and can feel pleasantly warm, especially in the shallows on calm days. Autumn brings a gradual 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 steady warm-up from about 18 °C into the low twenties as air temperatures rise.
Swimming Conditions
Swimming is allowed and very popular at Parsley Bay Beach, largely because of its calm, enclosed conditions. There is no surf, no rips, and very little current, making it well suited to families and relaxed swimming. A swimming net is often in place, adding extra confidence for bathers. Entry from the sand and nearby steps is easy, and the water is generally clear in dry weather. While water quality can drop briefly after heavy rain, Parsley Bay offers gentle, low-energy swimming for much of the year in a quiet harbour setting.
