*** 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
Melbourne is built around the winding curves of the Yarra River, and the river’s water temperature reflects the city’s cool-temperate climate. In summer, from December to February, the Yarra through Melbourne typically sits around 18–22°C, occasionally edging a bit higher in slow, sheltered sections during hot spells. Spring and autumn are cooler and variable, with water temperatures generally in the 14–18°C range. Winter brings the coldest conditions, often around 10–13°C, especially after rain or during prolonged cloudy weather. Runoff from the catchment and tidal influence near the lower reaches can cause short-term changes in both temperature and how the water feels.
Swimming Conditions
Swimming in the Yarra River at Melbourne is technically allowed, but it’s generally not recommended. While summer temperatures might look inviting, water quality can be inconsistent due to urban runoff, stormwater and boat activity. Visibility is often poor, and there are hidden hazards such as debris, steep banks and sudden depth changes. Currents can also be stronger than they appear, particularly after rain. Because of this, locals usually avoid swimming in the river itself and opt for nearby beaches, bayside swimming areas or public pools instead. In Melbourne, the Yarra is best enjoyed for walking, cycling, rowing and city views rather than as a place to take a dip.
