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.

The Mulgrave River flows out of the rainforest-covered ranges south of Cairns and down across the coastal plain toward the Coral Sea, and its water temperature stays relatively warm year-round thanks to the tropical climate. In summer, the river commonly sits between 26–30°C, especially in the lower and slower-moving sections, where the water can feel almost lukewarm on humid days. During the drier months of winter, temperatures usually ease back to around 22–25°C, which still feels comfortable rather than cold. Spring and autumn tend to fall in between, generally holding steady at about 24–27°C, making the river consistently inviting for a swim.
Swimming Conditions
Swimming in the Mulgrave River is generally allowed and enjoyed in suitable freshwater sections, particularly upstream where the water is clear and fast-flowing enough to stay fresh. These areas are popular for cooling off during hot weather, especially when conditions are dry and stable. Closer to the coast, tidal influence and murkier water make swimming less appealing. After heavy rain, which is common in the wet season, water levels rise quickly, temperatures can drop slightly, and strong currents make swimming unsafe. Outside of flood periods, the Mulgrave River offers warm water and refreshing swimming conditions, providing a pleasant alternative to the nearby beaches when the heat really sets in.
