*** 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
Finspång (Swedish: Finspång) in Östergötland County is surrounded by smaller lakes and slow-moving rivers whose surface temperatures vary strongly with the seasons. In summer, shallow lakes often warm to about 16–24 °C (61–75 °F), and during warm spells can reach around 25 °C (77 °F). Spring sees a rapid rise from near-freezing to cooler bathing temperatures, roughly 2–12 °C (36–54 °F) as ice melts. Autumn brings steady cooling, with waters falling from about 15 °C (59 °F) in early September to single digits by November, typically 4–10 °C (39–50 °F). In winter many lakes freeze or sit at about 0 °C (32 °F); flowing river sections that remain open are commonly close to 0–4 °C (32–39 °F).
Swimming in Finspång’s lakes and rivers is generally possible and commonly practised in warmer months because these water bodies are used for recreation and often have designated bathing spots. Access to public waters is widely available, but actual swimming can be limited temporarily by algal blooms, water-quality notices, private shorelines or safety warnings near currents and boat traffic. Cold-water risks apply outside the summer season, and ice swimming should only be done with proper precautions. For up-to-date safety and quality information, local signage and municipal advisories should be consulted before entering the water.
