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 Manning River flows from the Great Dividing Range to the NSW Mid North Coast, and its water temperature reflects a mild, coastal-influenced climate. In summer, from December to February, the river is usually a comfortable 22–26°C, sometimes feeling warmer in sheltered bends and backwaters during hot, still days. Spring and autumn are pleasant and steady, with water temperatures generally in the 18–22°C range. Winter is cooler but far from icy, typically around 14–18°C, especially in deeper sections where the water holds its warmth. Rainfall upstream can affect clarity and flow, but temperature changes are usually gradual rather than sudden.
Swimming Conditions
Swimming in the Manning River is generally allowed and widely enjoyed, particularly in summer. The water temperature during the warmer months is usually ideal for proper swimming, floating and cooling off on hot days. Locals tend to favour known river beaches and calmer stretches where access is easy and currents are gentle. Closer to the mouth, tidal movement and boat traffic mean swimmers need to be more cautious. After heavy rain, flows can increase and visibility can drop, making swimming less suitable for a while. With settled weather and sensible spot choice, the Manning offers some of the most relaxed and enjoyable river swimming on the Mid North Coast.
