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 Rottnen (Rottnen in Swedish) in Kronoberg County typically follows the seasonal temperature patterns of southern Swedish lakes. In spring the surface water usually rises from about 4–12 °C (39–54 °F) as ice melts and air temperatures warm. During summer the lake commonly reaches 15–22 °C (59–72 °F), with sheltered bays occasionally warming to about 24 °C (75 °F) in very warm spells. In autumn surface temperatures fall again to roughly 8–15 °C (46–59 °F) before the lake cools toward freezing, and in winter the water near and under ice is close to 0–4 °C (32–39 °F) when ice cover is present.
Swimming in and around Rottnen is generally permitted and is a popular activity in summer because of the accessible shoreline and relatively mild surface temperatures. Sweden’s public right of access (allemansrätten) allows people to enter the countryside, but local restrictions can apply near private property, water supply facilities or sensitive nature reserves, so checking local signs is advisable. Water quality can vary and occasional algal blooms or stagnant conditions may make swimming unadvisable; cold water and sudden temperature changes also pose risks, so appropriate caution, gradual immersion and attention to safety are recommended.
