*** 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
Hutt Lagoon, famously known as the Pink Lake, is a spectacular sight on Western Australia’s Coral Coast, just a short run north of Geraldton. Because it’s a massive salt flat that sits a few metres below sea level, the water temperature is heavily influenced by the searing WA sun. During the height of a stinking hot summer, the shallow waters can reach a toasty 25°C to 28°C, though you’ll often find much of the lake has dried up into crunchy salt crusts. In the cooler months between June and August, the mercury dips to a refreshed 18°C or 20°C. It’s the kind of warmth that makes you want to hop in, but the high salt content means the water holds its heat much differently than the nearby Indian Ocean.
Swimming Conditions
Swimming is technically allowed, but you’ve got to use your noggin before you dive in head-first. While there’s no official ban, most locals reckon it’s more of a look but don't touch situation because the water is incredibly salty—far more than the sea. If you’ve got any little nicks or scratches, they’ll stiiiing like a box jelly the moment you hit the water. The bottom is also lined with sharp salt crystals that’ll do a number on your feet, so wearing some old reef shoes is an absolute must if you're determined to float like a baby flamingo. Most folks prefer to save their big splash for the crystal-clear beaches at Port Gregory just over the dunes, keeping the lagoon for those legendary pink-water photos.
