*** 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
Sämsjön in Västra Götaland County is a typical Swedish small lake with marked seasonal changes in surface water temperature. In spring the lake warms from near freezing to about 4–10 °C (39–50 °F) as ice thaws and runoff cools the surface. During summer surface temperatures commonly reach 18–23 °C (64–73 °F), and in warm spells can approach 25 °C (77 °F) in shallow bays. In autumn the water cools back to roughly 8–14 °C (46–57 °F) as air temperatures drop and mixing increases. In winter the surface typically lies at or close to 0 °C (32 °F) under ice; open-water temperatures, if present, are generally below 4 °C (39 °F).
Swimming at Sämsjön is generally allowed during the ice-free season and many people use beaches, jetties or gently sloping shorelines for bathing; there are no universal bans but local rules or signage may apply. Water quality is often suitable for recreation in rural Västra Götaland lakes, though conditions vary with runoff, algal blooms and nearby land use, so checking local advisories is sensible. Winter ice swimming is practiced by some, but it requires proper precautions because of thin ice and hypothermia risk; safe swimming depends on season, weather and local safety measures.
