*** 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
Shark Beach sits inside Nielsen Park in Sydney’s eastern suburbs, overlooking the calm waters of Sydney Harbour rather than the open ocean. Because of its sheltered position, water temperatures here are generally steadier than along surf beaches. In summer, the harbour water usually ranges from about 22–26 °C and can feel especially warm in the shallows on still, sunny days. Autumn brings a gradual cooling to roughly 20–23 °C. Winter is cooler but still swimmable for many people, with temperatures typically between 16–20 °C, while spring sees a steady rise from around 18 °C into the low twenties as air temperatures improve.
Swimming Conditions
Swimming is allowed and very popular at Shark Beach, largely because of its calm and protected conditions. The beach is enclosed by a net, which helps keep marine life out and adds an extra level of confidence for swimmers. There are no waves or rips, making it well suited to families and relaxed swimming. Entry from the sand is easy, and the water is usually clear in dry weather. While water quality can dip after heavy rain, Shark Beach offers comfortable, low-energy swimming for much of the year, especially for those who prefer sheltered harbour water over surf conditions.
