*** 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
Borlänge (Swedish: Borlänge) sits inland in Dalarna County surrounded by lakes and rivers where water temperatures vary strongly with the seasons. Typical lake temperatures after ice-out in spring are low, often 1–10 °C (34–50 °F), warming in summer to roughly 15–22 °C (59–72 °F) on average, and cooling again in autumn to about 4–12 °C (39–54 °F). Rivers in the area tend to be a few degrees cooler and faster-moving: spring 1–8 °C (34–46 °F), summer commonly 12–18 °C (54–64 °F), and autumn 3–10 °C (37–50 °F). In winter most open water is ice-covered and sub-ice temperatures are close to 0–4 °C (32–39 °F). Local variations depend on depth, shading, inflows and recent weather, so shallow bays warm faster than deep basins.
Swimming in lakes and rivers around Borlänge is generally allowed; Sweden’s public right of access and local bathing areas mean many residents swim in summer at designated beaches and informal spots. Municipalities typically monitor popular bathing sites for water quality, but occasional advisories or closures can occur due to algae blooms or contamination. River swimming requires extra caution because of currents, cold inflows and boat traffic. Winter ice-swimming happens but demands proper safety measures, tested ice thickness and support. Overall, summer offers the most comfortable conditions for swimming, while spring and autumn are colder and winter requires specialist precautions.
