*** 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
Farum Sø is a modest-sized lake in the Capital Region of Denmark that shows marked seasonal variation in water temperature. In winter the surface often hovers close to freezing, roughly 0–4 °C (32–39 °F), and can freeze over in cold spells. Spring sees a steady rise as the lake warms to about 4–12 °C (39–54 °F), while summer brings the highest values, typically in the range 15–22 °C (59–72 °F) on warm days. In autumn temperatures decline again to roughly 6–15 °C (43–59 °F) as cooling air temperatures and increased rainfall lower the surface temperature. Local microclimates and wind can cause variation from these typical figures.
Swimming in Farum Sø is generally permitted and used by locals during the warmer months, especially at designated bathing spots where access and safety are better. Local authorities monitor water quality and may issue advisories or temporary bans if bacterial levels or blue‑green algal blooms make swimming unsafe. Even when officially allowed, water can be cool outside mid‑summer and swimmers should be aware of cold shock and depth changes; ice and very cold conditions in winter make bathing hazardous. Observing posted notices and municipal guidance ensures that swimming remains a safe recreational option.
