*** 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
Myall Lakes is a chain of large freshwater lakes on the Mid North Coast of New South Wales, surrounded by national park and bushland. Water temperature across the lakes follows the local coastal climate and varies gently through the seasons. In summer, the lakes usually warm to around 22–26°C, feeling comfortably warm and ideal for swimming. Spring and autumn are slightly cooler, generally sitting between 18–22°C, which still suits swimming on sunny days. During winter, water temperatures tend to drop to about 14–18°C, cool but not extreme, especially compared with inland lakes further south.
Swimming Conditions
Swimming in Myall Lakes is allowed and widely enjoyed, particularly in sheltered bays and near sandy shorelines where access is easy and the water is calm. The lakes are mostly shallow with little current, creating safe and relaxed conditions for casual swimming and floating. Water quality is generally good, especially during dry periods, as the lakes are largely freshwater and protected from heavy development. After prolonged rain, the water can become cooler and slightly tannin-stained, though this does not usually prevent swimming once conditions settle. Overall, Myall Lakes offer reliable and pleasant swimming opportunities for much of the year, combining moderate water temperatures with quiet, natural surroundings well away from crowded ocean beaches.
