*** 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
Murwillumbah is a proper inland beauty sitting in the shadow of Mount Warning, with the Tweed River snaking right through the heart of the town. Since we're away from the coast, the water temperature in this fresh-to-brackish stretch can get quite toasty. During the height of a humid summer, you’re looking at temperatures between 26°C and 28°C, which is spot on for a paddle. When the winter chill hits, the mercury dips down to a more refreshing 19°C or 21°C. While it’s rarely freezing, the river can look a bit murky after a heavy downpour in the caldera, so the locals usually wait for the silt to settle before thinking about a splash.
Swimming Conditions
Swimming is definitely allowed, and you’ll find some legendary spots if you head just a bit out of the main town area. One of the local favourites is the Palmers Road swimming hole, where the water is clear and the vibe is pure relaxation. The reason most folks stick to the upper freshwater reaches or the local aquatic centre in town is that the main river through Murwillumbah is a busy highway for boaties and rowers. There aren't any big salties to worry about this far south, but you’ve still got to keep your wits about you regarding submerged snags and the occasional strong current after rain. As long as you pick a quiet bank and check the water quality, it’s a cracker of a place to cool off.
