*** 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
Upplands Väsby (in Swedish – Upplands Väsby) contains several small lakes and slow-flowing streams typical of Stockholm County. Seasonal water temperatures in these inland waters vary: during winter the water under ice is usually close to 0 °C (32 °F), while spring sees a rapid rise to roughly 4–12 °C (39–54 °F). In summer inland lakes commonly reach 15–22 °C (59–72 °F), and during warm spells can peak around 24–25 °C (75–77 °F). Rivers and faster-flowing stretches tend to be a little cooler than standing water, often a degree or two lower, and autumn brings cooling back toward 5–12 °C (41–54 °F) before ice forms again.
Swimming in the lakes and rivers around Upplands Väsby is generally permitted and enjoyed at designated bathing sites and public access points. The municipality and county monitor water quality and post warnings if bacterial contamination or cyanobacteria make bathing inadvisable, so official beaches may be temporarily closed for health reasons. Lifesaving equipment and marked swimming areas are present at some sites, but open-water conditions vary, so swimmers are advised to heed local signage and exercise caution, especially in cold shoulder seasons; winter ice swimming occurs in organized groups with safety measures in place.
