*** Forecast - Our water temperature forecast
Actual lake water temperatures may differ from the reported values by several degrees, particularly during periods of strong winds or rapid weather changes. Wind can mix surface and deeper layers in a lake, bringing cooler water to the surface, while shallow areas may warm more quickly under direct sunlight. Air temperature, sunshine, and cloud cover strongly influence how quickly a lake heats up or cools down. These factors can lead to noticeable temperature variations across different parts of the lake.
Our forecast is based on a proprietary mathematical model that considers real-time lake temperature observations, historical trends, seasonal cycles, wind strength and direction, and region-specific air temperature. To enhance accuracy, we also incorporate data from nearby monitored locations and comparable lakes within Australia.

Location & Local Information
Lake Cargelligo sits out on the Lachlan floodplain in central western New South Wales, and its water temperature is very much shaped by the inland climate and seasonal inflows. In summer, from December through February, the lake commonly warms to around 22–28°C, and during extended hot spells it can feel even warmer in sheltered shallows. Spring and autumn are more moderate, with water temperatures generally in the 16–22°C range, which is comfortable on a sunny day but can feel cool in the mornings. Winter sees a clear drop, with the lake often sitting around 8–12°C, making the water feel brisk rather than inviting for long swims.
Swimming Conditions
Swimming in Lake Cargelligo is generally allowed and has long been part of local life, especially in summer when air temperatures regularly push into the mid to high 30s. The lake’s shallow edges and relatively calm conditions make it suitable for casual swimming and wading during warmer months. When the water is fresh and levels are healthy, the temperature is usually pleasant enough for a proper swim. However, conditions can change with drought, low inflows or prolonged heat. At times, water quality issues such as blue-green algae can occur, when swimming is best avoided. Keeping an eye on local advice and conditions helps ensure swimming here stays safe and enjoyable.
