*** 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
Lake Seppings sits just inland from the coast at Albany and is influenced by a cool, temperate climate with steady coastal breezes. Being shallow, the lake’s water temperature responds quickly to seasonal weather. In summer, it typically reaches around 18–22°C, which can feel refreshing rather than warm, especially when the wind is up. Spring and autumn usually sit between 14–18°C, while winter water temperatures often drop to about 10–14°C, giving the lake a distinctly cool feel. Cloud cover, wind, and overnight cooling can cause noticeable day-to-day changes.
Swimming Conditions
Swimming in Lake Seppings is generally not recommended. Although summer temperatures may look suitable on paper, the lake is managed as an urban wetland and recreational reserve rather than a swimming spot. Water quality can be variable due to urban runoff, nutrient levels, and periods of algal growth, particularly after rain. The lake is also an important habitat for birdlife and other wildlife, and human swimming would disturb the ecosystem. Access points are designed for walking and cycling, not safe water entry. Overall, Lake Seppings is best enjoyed for its scenic paths and nature values, with its seasonal water temperatures noted but swimming avoided in favour of safer, managed beaches and waterways nearby.
