*** 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
The Donssøerne (Don’s Lakes) in the Region of Southern Denmark typically show marked seasonal variation in water temperature. In winter the surface often sits around 0–4 °C (32–39 °F) and can approach freezing during cold spells. Spring warming brings temperatures up to roughly 4–12 °C (39–54 °F) as ice thaws and daylight increases. By summer the lakes commonly reach their warmest, often between about 18–24 °C (64–75 °F) on mild to warm days, though short heatwaves can push values a few degrees higher. In autumn the water cools again to roughly 8–15 °C (46–59 °F) as air temperatures drop and mixing increases. These ranges are typical for modest-sized lakes in Southern Denmark and will vary with weather, depth, and local inflows.
Swimming in Donssøerne is generally possible and often allowed, reflecting Denmark’s widespread public access to inland waters, but specific conditions determine whether it is advisable at any given time. Many people swim from informal banks or marked bathing spots when water quality is good and temperatures are comfortable; however, local rules, signage, and municipal guidance should be checked because occasional algal blooms, pollution events, or safety concerns (steep drop-offs, poor visibility, absence of lifeguards) can prompt temporary restrictions. Always heed posted information and test local conditions before entering the water.
