*** 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
Bourke sits on a classic outback stretch of the Darling River, where the climate has a strong influence on water conditions. Through summer, roughly December to February, water temperatures around Bourke are often warm, commonly in the 26–30°C range, and can feel hotter in slow-moving sections during prolonged heat. Spring and autumn tend to be more moderate, with the river usually sitting around 18–24°C.

Flow levels and temperature can shift depending on rainfall and upstream conditions.
Swimming Conditions
Swimming in the Darling River at Bourke is generally allowed, but it’s very much a case of picking the right time and place. In summer, the warm water can be appealing, especially when air temperatures climb well above 35°C. Locals tend to favour quieter, familiar spots where entry is easy and the current is gentle. However, the river demands caution. Water quality can vary, and during hot, low-flow periods there may be blue-green algae warnings, when swimming is best avoided. Submerged logs, soft banks and changing depths are also part of the picture. With local advice and sensible timing, a swim can be refreshing, but care is essential.
