*** 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
Muswellbrook sits on an inland stretch of the Hunter River, where the climate is more continental than coastal and seasons are clearly felt. Water temperatures here rise and fall with the air temperature and river flow. In summer, from December to February, the Hunter around Muswellbrook typically reaches about 20–25°C, sometimes feeling warmer in slow pools during extended hot spells. Spring and autumn are milder, with the river usually sitting in the 15–20°C range. Winter brings cooler conditions, often around 10–14°C, especially after cold nights, giving the water a sharp, refreshing feel. Rainfall and upstream releases can temporarily cool the river and change how it feels day to day.
Swimming Conditions
Swimming in the Hunter River at Muswellbrook is allowed and does happen, particularly in summer when inland temperatures climb. Locals tend to swim in familiar, calmer sections where access is easy and the current is manageable. During the warmer months, the water temperature is generally comfortable enough for a proper swim rather than just a quick dip. That said, conditions can vary. After heavy rain, flows can increase and visibility can drop, and there are deep holes and submerged snags in places. With settled weather and sensible spot choice, swimming around Muswellbrook can be a refreshing way to cool off.
