*** 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
Bacchus Marsh is a ripper of a town nestled in a fertile valley just west of Melbourne, where the Werribee River carves its way through some truly spectacular country. When it comes to the water temperature, it follows the classic Victorian seasonal swing that'll either have you diving in or keeping your boots on. During the peak of a scorching summer, the river pools can reach a comfortable 22°C to 25°C, providing a lush relief when the sun is beating down on the surrounding orchards. In the winter months, though, the mercury takes a proper dive, often dropping to a brisk 8°C or 12°C. It’s the kind of fresh that’ll give you a real wake-up call, so most locals wait for the warmer months before thinking about a soak.
Swimming Conditions
Swimming is definitely allowed and is a legendary pastime, especially if you head just out of town to the Werribee Gorge State Park. Spots like Needles Beach and Blackwood Pool are absolute gold for a wild swim, surrounded by ancient cliffs and native bush. The reason you’ve got to be a bit careful, though, is the water quality; because the river flow can be quite low and it carries runoff from upstream, it’s best to avoid a dip for a few days after heavy rain. As long as you stick to the clearer sections in the gorge and keep an eye out for submerged rocks or snags, it’s a top-notch way to experience the local landscape from a different perspective.
