*** 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
Gentofte Sø (Gentofte Lake) in the Capital Region of Denmark typically has cool, seasonally variable water temperatures. In winter the surface usually hovers around 0–4 °C (32–39 °F) and can partially freeze in cold spells. Spring sees a gradual rise to roughly 4–12 °C (39–54 °F) as the lake stratifies, while summer temperatures commonly reach 16–22 °C (61–72 °F), with occasional warm periods pushing toward 24–25 °C (75–77 °F). In autumn the water cools again into the range of about 8–15 °C (46–59 °F). These figures are typical averages; actual temperatures vary with weather, wind and water depth.
Swimming in Gentofte Sø is possible and the lake is used for recreation, but it is not formally managed like a monitored public beach. There is no blanket prohibition on entering the water, yet access can be limited by private shoreline, posted warnings, or temporary advisories. In late summer algal blooms or cyanobacteria can occur and lead authorities to recommend avoiding swimming; post-storm runoff can also affect water quality. For safety, swimmers should heed local signage, be aware of cold-water shock in spring/autumn, and note that lifeguards are generally not present. Checking municipal water-quality notices before swimming is advisable.
