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 Tweed River is a real coastal gem in the Northern Rivers region of New South Wales, where the warm tropical waters from the north meet the cooler southern currents. If you’re planning a dip, you’ll find the water temperature is an absolute dream for most of the year. During the peak of summer, the river water hits a balmy 26°C to 28°C, which is spot on for a long afternoon splash or a bit of snorkelling. Even when winter rolls around, the mercury rarely drops into freezing territory, usually hovering between a comfortable 19°C and 22°C. It’s the kind of waterway that stays inviting long after the southern rivers have started to bite, making it a favorite for year-round paddlers and swimmers alike.
Swimming Conditions
Swimming is definitely allowed and is a top-notch way to spend a day, especially at family-friendly spots like Jack Evans Boat Harbour or the sandy reaches near Fingal Head. The river is famous for its clarity near the mouth on an incoming tide, but you’ve got to keep your wits about you because the tidal currents can pull like a train in the deeper channels. While you don't have to worry about the big crocs found further north, it’s always smart to be SharkSmart—avoid swimming at dawn or dusk and stay out of the water for a few days after heavy rain when runoff can make things a bit murky. As long as you stick to the calm shallows and keep an eye on the tides, it’s a legendary spot to cool off and enjoy the scenery.
