*** 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
Gympie sits along the upper tidal reaches of the Mary River, where the water reflects the warm subtropical climate of south-east Queensland. Through summer, from December to February, river temperatures around Gympie are usually comfortable, commonly around 24–28°C, and can feel warmer in slow pools during long hot spells. Spring and autumn are milder, with water temperatures generally sitting between 20–24°C. Winter is cooler but still pleasant by most standards, typically around 16–20°C, especially in deeper sections where the water holds its warmth. Heavy rain upstream can cool the river temporarily and affect clarity, but overall temperatures remain fairly moderate year-round.
Swimming Conditions
Swimming in the Mary River at Gympie is allowed and does take place, particularly in summer when inland temperatures climb. The water is usually warm enough for a proper swim rather than just a quick dip, and locals tend to use familiar spots where access is easy and the current is gentler. That said, the river needs respect. After heavy rain, flows can rise quickly and visibility can drop, making swimming unsafe for a while. Further downstream, tidal influence and bull sharks are also factors. With settled weather and sensible spot choice, the Mary can offer a refreshing and enjoyable swimming option around Gympie.
