*** 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
Ballerup, a suburban municipality in the Capital Region of Denmark, has a mix of small lakes, ponds and slow-moving streams rather than large inland waters. Seasonal water temperatures in these bodies typically run from about 4–12 °C (39–54 °F) in spring, through roughly 17–22 °C (63–72 °F) in summer — with sheltered, shallow spots occasionally reaching 24–25 °C (75–77 °F) during warm spells — then cooling to about 8–15 °C (46–59 °F) in autumn and down to around 0–4 °C (32–39 °F) in winter when ice can sometimes form. Rivers and flowing reaches tend to be cooler than small, sun-exposed ponds, and shallow waters warm and cool more quickly with the weather.
Swimming in Ballerup’s lakes and streams is generally possible and not universally prohibited, but many sites are informal bathing spots rather than official, lifeguarded beaches. Local authorities monitor water quality and will advise against bathing when problems occur, for example after heavy rain that causes runoff, during algal blooms or when bacterial counts are high. Safety considerations such as depth, underwater obstacles and lack of lifeguards also influence whether a particular location is suitable for swimming, so checking municipal advisories and exercising caution is recommended.
