*** 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
Lake Nørresø (Danish: Nørresø) in the Region of Southern Denmark experiences the same temperate seasonal pattern as other Danish lowland lakes. In winter the surface water commonly lies close to freezing, roughly 0–4 °C (32–39 °F), while spring sees a steady rise to about 4–12 °C (39–54 °F) as the lake stratifies. Summer temperatures typically range between 16–22 °C (61–72 °F) and on warm, calm days can briefly reach around 24 °C (75 °F). In autumn the water cools again, usually falling to 8–16 °C (46–61 °F) before the lake mixes and approaches winter values. Local weather, depth, and inflows influence these numbers, so actual conditions at a given time may differ.
Recreational swimming in Nørresø is generally allowed and popular during the warmer months when temperatures are most comfortable. Municipal authorities or local signage normally indicate designated bathing spots and report water quality; routine monitoring for bacterial contamination and occasional blue‑green algal blooms can lead to temporary warnings or restrictions for health reasons. Swimmers should therefore follow posted guidance, be aware that deeper parts remain markedly colder even in summer, and take standard safety precautions related to water temperature, visibility and access.
