Water Temperature: Daily Trends, Historical Records, and Forecast
❌ As of today, the minimum water temperature ranges from 50°F (10°C) to 54°F (12°C). The water is slightly warmer, but still cool for most people. Swimming in such conditions is possible, but for most people, the time spent in the water should be limited to avoid hypothermia. Even experienced swimmers may feel discomfort if they stay in the water for too long. To improve comfort and safety, a wetsuit can be used. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

*** 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
Holsjön, a typical inland lake in Västra Götaland County, shows clear seasonal variation in surface water temperature. In summer months the surface commonly warms to roughly 18–24 °C (64–75 °F) on warm days, while late spring and early autumn temperatures are usually in the range of 6–15 °C (43–59 °F). During winter the lake can cool to near freezing, around 0–4 °C (32–39 °F), and may develop stable ice cover some winters depending on local weather. Deeper water remains colder year-round and responds more slowly to air temperature, so divers and swimmers will notice a marked thermocline on warm, calm days.
Swimming in Holsjön is generally permitted and often practiced, reflecting Sweden’s public right of access and the common use of natural waters for recreation. Whether a particular spot is suitable depends on local amenities, water quality monitoring and safety features; some areas have maintained beaches and dressings, while others are more remote without lifeguards. Occasional algal blooms or low oxygen in late summer can lead authorities to advise against bathing, and winter ice swimming is a distinct activity but requires caution because of thin ice and hypothermia risk. Visitors should follow local signage and municipal guidance.
