*** 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
Around Katrineholm in Södermanland the lakes and slow rivers follow the typical inland Swedish seasonal cycle. In spring surface temperatures usually rise from near freezing to roughly 4–12 °C (39–54 °F) as ice breaks up; summer surface temperatures commonly range from about 18–22 °C (64–72 °F) and can reach 24–26 °C (75–79 °F) during warm spells. In autumn waters cool back through roughly 15–8 °C (59–46 °F) and by winter many smaller lakes are ice-covered with surface temperatures at or near 0 °C (32 °F), while deeper water under ice is closer to 4 °C (39 °F). Flowing rivers around Katrineholm are generally a few degrees colder than lakes and may remain cooler year‑round depending on flow and shading.
Swimming in lakes and designated bathing areas is generally allowed and common, supported by the Swedish public right of access (allemansrätten) and municipal maintenance of public beaches, which are often monitored for water quality in summer. Caution is advised: river currents, sudden depth changes and lower temperatures increase risk, and winter ice and very cold water make unprepared bathing hazardous. Local signage and municipal advisories should be followed for safety and hygiene.
