*** 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
Casino sits on a broad inland stretch of the Richmond River, where the water is fresh and strongly shaped by the Northern Rivers’ subtropical climate. Water temperatures here are inviting for much of the year. In summer, from December to February, the river around Casino usually sits around 22–26°C, and in slower pools it can feel a bit warmer during long hot spells. Spring and autumn are comfortable and steady, with water temperatures generally in the 18–22°C range. Winter is cooler but still manageable, typically around 14–18°C, especially in deeper sections where the water holds its warmth. After heavy rain, fresh inflows can briefly cool the river and increase the flow.
Swimming Conditions
Swimming in the Richmond River at Casino is allowed and is a common local pastime in the warmer months. In summer, the water temperature is usually pleasant enough for proper swimming rather than just a quick dip. Locals tend to choose familiar upstream spots and calmer stretches where access is easy and currents are gentle. Being well inland, this part of the river is free from tidal influence and marine hazards, which makes swimming more relaxed than closer to the coast. That said, conditions can change after heavy rain, when flows rise and visibility drops. With settled weather and sensible spot choice, swimming around Casino is refreshing and enjoyable.
