*** 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
Bastrup Sø (Bastrup Lake) in the Capital Region of Denmark typically shows clear seasonal variation in surface water temperature. In winter the lake is cold, often near freezing with temperatures around 0–4 °C (32–39 °F), and ice can form in cold spells. Spring brings gradual warming to roughly 4–12 °C (39–54 °F) as daylight and air temperatures increase. During summer the surface commonly reaches 16–22 °C (61–72 °F), and in warm, calm summers it can briefly climb toward 24 °C (75 °F) in shallow bays; deeper water stays cooler. Autumn sees a steady decline, with temperatures usually in the 8–15 °C (46–59 °F) range. Local weather, wind and depth all influence these figures, so conditions vary from day to day.
Swimming in Bastrup Sø is generally possible and used recreationally because the lake has accessible shores and is part of the public natural environment, but there are no universal guarantees of access or safety. Whether people choose to swim depends on water quality, seasonal temperature and any posted restrictions; in summer the temperature is most comfortable, while winter swimming is only for experienced, well-prepared individuals due to hypothermia risk. Visitors should observe local signs, check for any advisories about pollution or algae, and be aware that lifeguards are not usually present.
