*** 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
Geelong sits near the lower reaches of the Barwon River, where the river slows and broadens before meeting the coast. Water temperature here reflects Victoria’s cool-temperate conditions. In summer, from December to February, the Barwon around Geelong typically sits at about 18–22°C, sometimes nudging a little higher in sheltered bends during hot, still days. Spring and autumn are milder, with water temperatures generally in the 14–18°C range. Winter is noticeably cooler, often around 9–13°C, particularly after rain or during long overcast spells. Because this is a lowland section, temperatures change gradually rather than sharply, though tides can subtly influence how warm the water feels.
Swimming Conditions
Swimming in the Barwon River near Geelong is allowed and does happen, especially in summer when the weather warms up. Locals often choose calmer, well-known stretches upstream of the tidal zone, where access is easy and the current is gentle. In warm weather, the water temperature is usually comfortable enough for a proper swim, even if it still feels refreshing rather than warm. That said, conditions vary. After heavy rain, flows can increase and visibility can drop, and closer to the river mouth tidal movement and boat traffic make swimming less suitable. With settled weather and sensible spot choice, the Barwon offers a pleasant freshwater swimming option around Geelong.
