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
Flåsjön in Jämtland County is a freshwater lake whose surface temperatures follow the marked seasonal rhythm of the Swedish inland. In spring the water is cold, commonly around 1–10 °C (34–50 °F) as snowmelt and cool air keep temperatures low. During summer months surface readings often climb into the range of roughly 12–22 °C (54–72 °F) on warm sunny days, though cooler winds and depth can keep some spots several degrees lower. In autumn the lake cools back toward about 5–12 °C (41–54 °F), and in winter the surface typically freezes or sits just above 0 °C (32 °F), with liquid water below the ice at slightly higher but still near-freezing temperatures.
Swimming at Flåsjön is generally possible and common in summer, thanks to Swedish access rights and informal local use, but it is not formally supervised and conditions vary. Bathing is allowed unless specific local restrictions are posted, yet swimmers should be mindful of cold-water hazards, sudden weather changes, underwater obstacles and the absence of lifeguards. For safer and more comfortable swims consider sheltered bays, warmer days, short exposures or a wetsuit; experienced cold-water enthusiasts sometimes use cut ice for winter dips, but that requires proper safety precautions and knowledge.
