*** 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
Storsjön in Gävleborg County typically follows the seasonal temperature pattern of mid‑Swedish lakes. In spring (April–May) surface temperatures commonly range from about 2–10 °C (36–50 °F) as ice melts and the water slowly warms. The bathing season peaks in June–August when sheltered bays and shallower areas often reach 15–22 °C (59–72 °F), with warm spells pushing local spots a few degrees higher. In autumn (September–October) temperatures drop back to roughly 5–12 °C (41–54 °F) as cooling resumes, and winter brings near‑freezing conditions around 0–4 °C (32–39 °F), frequently with ice cover on parts of the lake.
Swimming at Storsjön is generally possible and commonly practiced during the warmer months because the water attains comfortable bathing temperatures and public access to shoreline areas is permitted under Swedish access rights. Local beaches or boat ramps provide usual entry points, but safety and water quality can vary by spot and season, so visitors should heed signage, avoid thin ice in shoulder seasons, and be cautious about sudden depth changes and cold shock. Ice swimming may occur where locals maintain safe holes, but it requires proper precautions and experience.
