*** 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
Solna (Swedish: Solna) in Stockholm County includes several small lakes, ponds and slow-flowing waters whose temperatures follow the regional seasonal cycle. In spring (March–May) surface temperatures commonly rise from around 2–10 °C (36–50 °F). Early summer (June) typically brings 10–18 °C (50–64 °F). In July–August shallow lakes and sheltered waters often reach their warmest, roughly 18–24 °C (64–75 °F), while deeper or faster-flowing spots usually stay a few degrees cooler. In autumn (September–November) temperatures fall again toward 5–12 °C (41–54 °F) and by winter many inland ponds and small lakes freeze or sit close to 0 °C (32 °F). Rivers and channels connected to larger water bodies can be cooler and more variable than small, sun-warmed lakes.
Swimming in Solna’s freshwater is generally possible in warmer months where public access exists, but it depends on local water quality, signage and safety conditions rather than a blanket rule. Municipalities and county authorities monitor bathing water and post recommendations; cyanobacterial blooms, turbidity or strong currents can lead to temporary advisories against bathing. Ice swimming is practiced by some in winter, but that requires proper ice thickness, supervision and safety measures. Always check local notices and use designated bathing spots when available for the safest experience.
