*** 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
Carnarvon sits near the mouth of the Gascoyne River, a river that’s better known for its floods than for steady year-round flow. When there is water in the river, its temperature reflects the warm, dry climate of Western Australia’s mid-west. In summer, from December to February, water temperatures can be quite warm, often around 25–30°C, especially in shallow pools left after flows. Autumn and spring tend to be a little milder, usually sitting in the 20–26°C range. Winter is noticeably cooler but still comfortable by Australian standards, with water temperatures generally around 16–20°C. Because the Gascoyne is an intermittent river, these figures can vary a lot depending on recent rainfall and how long water has been sitting in the channel.
Swimming Conditions
Swimming in the Gascoyne River at Carnarvon is allowed, but it’s very dependent on conditions. For much of the year the riverbed is dry, so swimming is only possible after significant rain or flood events, when pools and channels fill. When water is present and fresh, locals may swim in calm, clear sections, and the temperature is usually pleasant, especially outside winter. However, water quality can decline as pools stagnate, and uneven banks, soft sand and debris are common. For this reason, swimming tends to be occasional rather than routine, with people choosing spots carefully and only when conditions are right.
