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
Sollentuna, in Stockholm County, has a landscape shaped by small lakes and streams that follow typical Swedish seasonal cycles. In winter many lakes freeze and surface water temperatures sit at or just above 0 °C (32 °F). In spring, after ice melt, surface temperatures commonly range from about 0–10 °C (32–50 °F). By early summer lakes and slow-moving rivers warm to roughly 10–18 °C (50–64 °F), and peak midsummer temperatures in July–August are often between 18–24 °C (64–75 °F), occasionally rising above 25 °C (77 °F) during hot spells. In autumn temperatures fall back through the 10–15 °C (50–59 °F) range before refreezing.
Swimming in Sollentuna’s lakes and rivers is generally allowed and common; Swedish public access traditions and municipal bathing areas mean people may bathe unless specific restrictions apply. Local authorities monitor popular bathing spots for water quality, and temporary advisories can be issued for algal blooms or pollution. Safety considerations include cold water shock in shoulder seasons and modest currents in some streams. Access to shoreline immediately adjacent to private dwellings should be respected, so swimmers are advised to follow local signs and municipal guidance for designated bathing locations.
