*** 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

Tweed Heads is a proper coastal paradise where the Tweed River meets the Pacific, and the water here is as inviting as a cold drink on a hot Friday afternoon. Being right on the border with the Sunshine State, the river stays pretty tropical and lush for most of the year. In the height of summer, you’re looking at water temperatures peaking around 26°C to 28°C, which is absolute gold for a long soak. Even when winter rolls around in August, the mercury rarely drops below 19°C or 22°C, so you can still have a splash without your teeth chattering, though the locals might reach for a thin spring suit if the breeze picks up.

Swimming Conditions

Swimming is definitely allowed and is a top-tier way to spend the day, with Jack Evans Boat Harbour being a standout choice for a calm, protected dip. It’s a ripper of a spot because it’s tucked away from the main river traffic and usually boasts crystal-clear water on an incoming tide. You’ve got to use your noggin, though, as the main river channels can have currents that pull like a train and plenty of boaties zooming past. While the lower estuary is generally top-notch, it’s best to steer clear for a few days after a heavy downpour when runoff can make things a bit murky. As long as you stick to the sandy shallows and keep an eye on the tides, it’s a legendary place to cool off.
