Water Temperature: Daily Trends, Historical Records, and Forecast
❌ As of today, the minimum water temperature ranges less than 41°F (5°C). Such water is extremely cold and not recommended for swimming without proper preparation. In these conditions, the risk of hypothermia is very high, and prolonged exposure to the water can be hazardous to your health. If you decide to swim, it is important to have the appropriate gear, such as a wetsuit. Typically, only experienced swimmers or those who practice winter swimming venture into such waters. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

*** Forecast - Our water temperature forecast
Actual nearshore water temperatures may fluctuate by several degrees from the reported values, especially following heavy rainfall or extended periods of strong winds. Certain wind patterns can cause colder, deeper waters to rise and replace the sun-warmed surface water, leading to noticeable variations.
Our forecast is based on a proprietary mathematical model that considers real-time water temperature changes, historical trends, key weather patterns, wind strength and direction, and air temperature specific to each region. Additionally, we incorporate data from other resorts to enhance accuracy.

Location & Local Information
The lake Femunden (Norwegian name: Femunden) is a large, upland lake and its water remains relatively cold year-round due to elevation and northern climate. In spring, as ice breaks up, surface temperatures typically range from about 0 to 6 °C (32 to 43 °F). During the high summer months the warmest surface readings are usually between 10 and 16 °C (50 to 61 °F), and in sheltered bays on warm, calm days temperatures can occasionally approach 18 °C (64 °F). In autumn the water cools again to roughly 4 to 8 °C (39 to 46 °F), while winter brings ice cover and surface water at or around 0 °C (32 °F), with deeper water nearer to 4 °C (39 °F) where density effects stabilize temperatures.
Swimming in Femunden is permitted and commonly practiced in summer, but conditions are distinctly cool compared with more southern lakes. The combination of low temperatures, sudden weather changes and the lake’s remote locations means that swims are generally brief unless a wetsuit is used; visitors should take standard safety precautions, enter slowly to avoid cold shock, and be aware there are few lifeguarded areas. Ice swimming or winter bathing is possible where ice conditions are safe, but it requires specialist experience and equipment.
