*** 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
It’s a massive expanse of water that’s basically the local playground for anyone looking to beat the heat. During the height of a cracking summer, the surface water temperature usually hovers around a balmy 24°C to 26°C, making it absolutely spot on for a long dip or a bit of a splash with the family. However, don't let the summer sun fool you; once winter rolls around, the mercury in the water dives down to about 10°C or 12°C. It’s definitely fresh enough to take your breath away then, so most folks stick to the shore unless they’re keen on a bit of cold-water therapy.
Swimming Conditions
Swimming is perfectly fine and is a huge drawcard for the area, especially at popular spots like Ebden Reserve or the Lake Hume Tourist Park beach. There aren't any pesky sharks to worry about, but you’ve got to keep a sharp eye out for submerged trees and shifting water levels, as the lake is a working dam. It’s also worth checking the local alerts for blue-green algae before you jump in, as the warm, still water in late summer can sometimes cause a bit of a bloom. As long as you play it smart and watch the kids, it’s a ripper place to spend a Saturday afternoon.
