*** 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
Norra Öllesjön in Blekinge typically follows the seasonal temperature patterns common for small southern Swedish lakes. In spring surface temperatures often rise from around 3–10 °C (37–50 °F) as the ice thaws and sun returns. In summer the surface commonly reaches 15–22 °C (59–72 °F) on warm days, making swimming most comfortable in June through August. Early autumn sees cooling to roughly 10–16 °C (50–61 °F) before winter brings near-freezing conditions around 0–4 °C (32–39 °F), and the lake can freeze over some winters. Deeper water remains colder year-round, so conditions just below the surface are noticeably chillier than the reported surface values.
Swimming at Norra Öllesjön is generally possible and often practiced during the summer months; Swedish access rights (allemansrätten) allow public recreation along many shorelines, though private land and posted restrictions still apply in places. There are usually no formal lifeguards or extensive facilities, so swimmers should use common-sense precautions: be aware of colder water at depth, watch for aquatic vegetation or slippery banks, and avoid prolonged exposure in cooler temperatures. Water quality and local rules can vary, so checking local notices or signs before entering the water is advisable.
