*** 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
Vallsjön, as it is called in Swedish, is a typical inland lake in Jönköping County with seasonal surface temperatures that reflect the temperate Swedish climate. In summer (June–August) the water commonly warms to about 18–23 °C (64–73 °F) and can reach around 24–25 °C (75–77 °F) during prolonged heat. In spring (April–May) temperatures are lower, commonly in the 4–12 °C range (39–54 °F) as the lake sheds ice and cools, while early autumn (September) often sees 8–15 °C (46–59 °F) before falling back toward near‑freezing conditions in late autumn and winter. During winter months the surface is frequently close to 0 °C (32 °F) and the lake may be ice‑covered for periods.
Swimming at Vallsjön is generally possible and commonly practiced where there is public shoreline access, as Swedish public access rights permit bathing and recreational use of many lakes. Whether swimming is advisable at a particular time depends on water quality, local rules, and safety conditions: in summer the temperatures are comfortable for most swimmers, whereas spring and late autumn waters are cold and carry a higher risk of cold shock and hypothermia. In winter ice‑bathing occurs in some places but requires proper precautions, local knowledge of ice thickness, and appropriate safety measures. Always observe posted signage and local guidance.
