*** 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
Wamberal Lagoon is a coastal beauty on the Central Coast of New South Wales, tucked behind the dunes of Wamberal Beach. Because it’s a relatively shallow, semi-enclosed body of water, it tends to warm up beautifully in the sun. During a cracking summer, the water temperature usually hits a balmy 23°C to 26°C, making it feel more like a warm bath than the open ocean. It’s a top spot for a bit of a splash when the sea breeze is kicking up spray on the beach. Even in the middle of winter, the mercury rarely drops into freezing territory, typically hovering between 16°C and 19°C, though you’ll mostly see the local birdlife enjoying it then.
Swimming Conditions
Swimming is definitely allowed and is a legendary choice for families with little ones, as the calm, protected waters are a world away from the heavy rips and swells of the main beach. It’s absolute gold for a bit of a float or some low-key paddleboarding. However, you’ve got to use your noggin and check the local water quality alerts before jumping in. Because the lagoon acts as a natural buffer for stormwater, the bacteria levels can spike after a heavy downpour, so the local council generally reckons you should steer clear for about three days after rain. As long as the sun’s been out and the entrance isn't choked with weed, it’s a ripper spot to cool off in a more relaxed setting.
