*** 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
Windsor is a historic gem tucked along the banks of the Hawkesbury River in Greater Western Sydney, and the river is the absolute heart of the town. When it comes to the water temperature, it’s a fair dinkum treat for most of the year. During the scorching summer months, you’re looking at balmy temperatures between 23°C and 26°C, though on a real stinker of a day, the shallower parts can feel even warmer. In the winter, the mercury drops quite a bit, usually hovering between 13°C and 16°C. It’s a bit of a fresh one then, so unless you’re as tough as nails, you’d probably stick to the banks or wear a thick steamer if you’re heading in.
Swimming Conditions
Swimming is technically allowed at spots like Macquarie Park—often called Windsor Beach—but you’ve got to keep your wits about you. It’s a popular spot for a paddle because of the sandy banks, but the council often puts out warnings because the Hawkesbury is a powerful tidal river with deep drop-offs and currents that pull like a train. It’s also wise to check the Beachwatch alerts, as the water can get a bit murky or have high bacteria levels after a heavy downpour. If the river is looking a bit rough or the current is ripping, most of the locals head to the Hawkesbury Oasis in South Windsor for a worry-free soak, but on a calm day, the river is a legendary spot to cool off.
