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

Stor-blåsjön (Swedish: Stor-blåsjön) is a mountain lake in Jämtland County where seasonal water temperatures vary markedly. In summer, surface temperatures commonly range from about 12–18 °C (54–64 °F) and in warm spells can reach 20–22 °C (68–72 °F) in sheltered, shallow bays. During spring and early summer, after ice melt, temperatures are typically low, around 4–8 °C (39–46 °F). In autumn the water cools again to roughly 4–10 °C (39–50 °F). In winter the lake is usually ice-covered and the water beneath the ice sits close to 0 °C (32 °F); any open-water holes used for winter bathing will be at or just above freezing.

Swimming at Stor-blåsjön is generally permitted as it is natural public water, and many people swim there in summer where shore access allows. There are usually no formal bathing facilities or lifeguards, so swimmers should judge conditions themselves, be aware of cold-water shock and hypothermia risks, and use wetsuits or flotation for longer swims. Normal swimming is not practical when the lake is frozen; ice bathing is practiced by some, but requires careful safety measures, local knowledge, and attention to any rules or signage that may restrict access.
