*** 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 Lyndon, in the Canterbury Region along the inland route between Christchurch and the West Coast, is a small alpine lake set among open high country hills. Its elevation and exposure to mountain weather keep water temperatures cool for much of the year. In winter, surface temperatures are generally around 4–7°C, and frosty conditions are common around the shoreline. During spring, snowmelt and cool winds maintain temperatures typically between 6 and 10°C. In summer, particularly in January and February, sheltered near-shore areas may warm to approximately 11–16°C on calm, sunny days, while deeper water remains colder. By autumn, temperatures usually ease back to between 7 and 12°C. Strong winds can quickly mix the surface water.
Swimming Conditions
Swimming is allowed at Lake Lyndon, but it is not widely used as a swimming destination due to the consistently cool conditions. Even in mid-summer, water temperatures generally remain in the low to mid teens, which can feel brisk. The most suitable time for a brief swim is during settled summer weather when winds are light. Swimmers should choose sheltered spots and enter gradually to reduce the risk of cold shock. Checking weather conditions beforehand helps ensure a safer and more comfortable experience.
