*** 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
Lake Slivsø (Danish: Slivsø) in the Region of Southern Denmark typically follows the seasonal patterns of shallow Danish lakes, with surface water temperatures that vary considerably through the year. In winter the lake often approaches near-freezing conditions, roughly 0–4 °C (32–39 °F). Spring warming brings temperatures up to about 4–12 °C (39–54 °F) as ice melts and sunlight increases. In summer the surface commonly ranges from about 16–22 °C (61–72 °F), and during warm spells can locally reach the mid-20s °C (around 75 °F). Autumn cooling typically lowers temperatures to roughly 8–14 °C (46–57 °F). Actual readings depend on air temperature, wind, depth and local inflows, so values can vary from year to year.
Swimming in Slivsø is generally permitted and used recreationally, as many Danish lakes are public resources, but it is subject to local rules and water-quality considerations. Municipal monitoring and signage indicate when bathing is considered safe; swimmers should avoid areas with visible algal scums or posted warnings about bacteria or cyanobacteria, which can occur in warm late summer. Access can also be limited by vegetation or private shoreline sections. Cold-water risks in shoulder seasons mean that wetsuits and caution are advisable outside the warmest months. Always follow local notices for up-to-date guidance on swimming safety.
