*** 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
Alingsås (in Swedish - Alingsås) lies inland in Västra Götaland County, surrounded by lakes and smaller rivers whose surface temperatures vary seasonally and with depth. In spring surface waters typically rise from around 3–10 °C (37–50 °F) as ice breaks up and air temperatures climb. Summer is the warmest period, with many shallow bays and small lakes commonly reaching 18–24 °C (64–75 °F) on warm days; deeper basins remain cooler. During autumn surface temperatures decline to roughly 8–15 °C (46–59 °F) as cooling and mixing begin. In winter open water near the surface can approach 0 °C and, where lakes freeze, the liquid water beneath the ice is generally close to 0–4 °C (32–39 °F). Flowing rivers often stay colder than sheltered lakes and respond more rapidly to weather changes.
Swimming in Alingsås’ lakes and rivers is generally permitted and popular in summer where access points and beaches exist, but it depends on local rules, water quality and safety conditions. Authorities and property owners may close or advise against bathing during algal blooms, heavy rain runoff, or poor bacterial test results. In winter some people practice ice swimming, but safe participation requires verified ice thickness, local guidance and precautions. Because temperature, currents and underwater hazards vary, swimmers should choose designated bathing spots, heed warnings and be aware that river currents and cold water present additional risks.
