*** 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.

Swimming Conditions
Swimming in the Noosa River around Tewantin is allowed and popular, especially in sheltered areas away from main boating channels. The river is wide and slow-moving here, with minimal wave action and gentle currents, which suits casual swimming and cooling off in hot weather. Water quality is usually good, particularly during dry periods, and the absence of surf makes it a relaxed option for families and less confident swimmers. After heavy rain, the water can become slightly cooler and murkier, so locals often wait for conditions to settle. In stable weather, Tewantin offers consistently warm, safe river swimming and a reliable alternative to the nearby ocean beaches.
