Water Temperature: Daily Trends, Historical Records, and Forecast
❌ As of today, the minimum water temperature ranges from 47°F (8°C) to 50°F (10°C). This is still cool water, suitable only for experienced swimmers or those accustomed to cold water. Swimming in such conditions is possible, but not recommended for prolonged periods. Extra caution should be taken during extended exposure, as the cold water can cause heat loss and lead to hypothermia. For added comfort, special clothing can be used. 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
Strandavatnet is a mountain reservoir in the former Buskerud area of Norway, and its water temperature reflects its elevation and northern climate. In winter the surface is typically at or just above freezing, roughly 0–4 °C (32–39 °F) beneath or next to ice; during spring thaw temperatures commonly rise through 2–8 °C (36–46 °F). Summer brings the warmest conditions, but even then the lake often remains cool, with surface temperatures generally in the 8–16 °C range (46–61 °F) and only occasionally reaching higher on very warm, calm days. In autumn the water cools again, commonly falling to 4–10 °C (39–50 °F) as air temperatures drop and mixing increases.
Swimming in Strandavatnet is physically possible and frequently done in the warmer months, but several factors affect whether it is advisable. As a mountain reservoir there can be sudden changes in water level, cold thermal layers, and no lifeguards, so local rules or operational restrictions tied to hydropower use may apply in places; access can also be limited by steep or rocky shores. Because of the persistently low temperatures, swimmers should be cautious about cold-water shock and hypothermia—short dips or wetsuits are common precautions. Always check local signage and conditions before entering the water.
