*** 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.

The Murray River stretches across south-eastern Australia and runs through a mix of warm inland plains and cooler southern regions, so water temperatures change noticeably through the year. In summer, from December to February, the river commonly sits between about 22 °C and 26 °C, with some shallow sections warming a bit more during heatwaves. Autumn brings a gradual drop into the 16–20 °C range, while winter temperatures are much cooler, often around 10–14 °C. In spring, the water slowly warms again, usually reaching 15–20 °C by late October or November, depending on local weather and flow conditions.

Swimming Conditions

Swimming in the Murray River is generally allowed and quite popular in many towns and camping areas, especially during the hotter months when the water offers welcome relief from the heat. However, conditions can vary a lot along its long course. Currents may be stronger after rain or water releases, and some sections have cold inflows from dams or irrigation channels. Water quality is usually suitable for recreation, but algae blooms can occur in warmer periods, and locals keep an eye on advisories. With sensible precautions and local knowledge, the Murray is widely used for swimming, paddling, and cooling off on a hot Aussie day.
