*** 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.

Brisbane Water is a broad tidal river system on the Central Coast of New South Wales, sheltered from the open Tasman Sea and influenced by both freshwater inflow and ocean tides. Water temperatures here are generally a little warmer and more stable than along nearby surf beaches. In summer, the river commonly sits around 22–26 °C, and can feel even warmer in shallow, sheltered bays on still days. Autumn brings a gradual cooling to roughly 20–23 °C. Winter is cooler but still manageable for many swimmers, with temperatures usually around 16–20 °C, while spring sees a steady warm-up from about 18 °C into the low twenties as air temperatures rise.
Swimming Conditions
Swimming is allowed and popular in Brisbane Water, particularly in calm bays and along sandy shorelines away from boat channels. The sheltered nature of the river means there are no waves and far fewer hazards than the open ocean, making it suitable for relaxed swimming and paddling. However, water quality can vary depending on rainfall, tides, and boat activity, so choosing clear, calm days is important. Strong tidal flows can occur in narrow sections, and boat traffic is common in some areas. When conditions are right, Brisbane Water offers gentle, accessible swimming with warmer-feeling water and a peaceful estuary setting.
