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
Source: • location Tararua Ranges Mouth: • location Wellington Harbour • elevation 0 m (0 ft) Length 56 km
The Hutt River flows from the Tararua Ranges through Upper and Lower Hutt before entering Wellington Harbour. As a river that begins in cooler hill country and runs through urban areas, its water temperature varies clearly with the seasons. In winter, temperatures are generally around 8–12°C, particularly in the upper reaches. During spring, the river gradually warms to approximately 12–16°C. In summer, especially in January and February, calmer stretches and deeper pools can reach about 17–22°C on warm days, while faster-flowing sections may feel cooler. In autumn, temperatures typically ease back to between 13 and 17°C. Heavy rain in the ranges can briefly lower water temperatures and significantly increase flow.
Swimming Conditions
Swimming is allowed in suitable parts of the Hutt River, and several popular swimming holes are used during the warmer months. The most comfortable conditions are usually in mid to late summer when water temperatures approach or exceed 18°C and river levels are steady. However, swimmers should be aware of moderate currents, variable depths and occasional debris after rainfall. It is advisable to avoid swimming during high flows or shortly after heavy rain, when water clarity may be reduced. Checking regional water quality updates before entering the river is recommended for safety.
