*** 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

Wollumboola Lake is a shallow coastal lake on the NSW South Coast, separated from the ocean by a sand barrier and strongly influenced by local weather and rainfall. Water temperature here changes with the seasons and can fluctuate fairly quickly because of the lake’s shallow depth. In summer, Wollumboola Lake typically warms to around 22–26°C, which feels comfortably warm on calm, sunny days. Spring and autumn usually sit between 18–22°C, remaining mild enough for a dip when conditions are settled. During winter, water temperatures often fall to about 14–17°C, making the lake feel cool, especially after cold nights or windy weather.

Swimming Conditions

Swimming in Wollumboola Lake is generally not recommended. Although the water temperature in summer may appear suitable, the lake is not managed as a recreational swimming area and water quality can be inconsistent. Limited water circulation, occasional algal growth, and runoff after rainfall can affect clarity and safety. After heavy rain, conditions often deteriorate further, with cooler water and reduced quality. For these reasons, locals and visitors usually avoid swimming and instead use nearby beaches or managed waterways. Overall, Wollumboola Lake is best appreciated as a natural and ecological feature, with its seasonal water temperatures noted but swimming discouraged due to variable and unpredictable conditions.
