*** 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
Långasjön in Blekinge experiences a clear seasonal variation in water temperature. During summer months the surface typically warms to about 16–22 °C (61–72 °F), and on warm spells can reach 24–25 °C (75–77 °F). In spring temperatures are cooler, often in the 4–12 °C range (39–54 °F) as the lake stratifies, while autumn sees a gradual decline to roughly 8–14 °C (46–57 °F). In winter the lake can approach freezing with surface readings near 0–4 °C (32–39 °F) and occasional ice cover in colder years. These numbers are approximate and vary with weather, depth and local inflow.
Swimming in Långasjön is generally allowed and commonly practised in warmer months because the lake has public access points and recreational shorelines. There is no general prohibition, but local rules or temporary advisories may restrict bathing for reasons such as water quality issues, blue-green algae, or maintenance. Swimmers should be mindful of colder temperatures outside summer, which increase the risk of cold-water shock and reduced endurance, and take normal safety precautions such as supervising children, using flotation when needed, and checking local notices about water quality before entering.
