Water Temperature: Daily Trends, Historical Records, and Forecast
❌ As of today, the minimum water temperature ranges from 47°F (8°C) to 50°F (10°C). This is still cool water, suitable only for experienced swimmers or those accustomed to cold water. Swimming in such conditions is possible, but not recommended for prolonged periods. Extra caution should be taken during extended exposure, as the cold water can cause heat loss and lead to hypothermia. For added comfort, special clothing can be used. It is important to note that these swimming tips and recommendations apply only in good weather. When the air temperature is below 68°F (20°C), and sometimes even below 77°F (25°C), swimming can be unpleasant even with relatively high water temperatures.

*** 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
Allgunnen (Allgunnen) in Jönköping County typically follows the seasonal temperature patterns of small Swedish lakes. In spring the surface water usually warms from near freezing to about 2–10 °C (36–50 °F) as ice melts and air temperatures rise. During summer months the surface commonly reaches 18–23 °C (64–73 °F) on average, and in warm spells it can climb toward 24–26 °C (75–79 °F) in shallow bays. Autumn brings a steady cooling, with waters dropping to roughly 5–12 °C (41–54 °F). In winter the lake surface is often at or just above 0 °C (32 °F) when ice forms; water beneath the ice remains around 0–4 °C (32–39 °F).
Swimming in and around Allgunnen is generally permitted and used for recreation, consistent with Sweden’s tradition of public access to nature and the presence of informal or municipal bathing spots along the shoreline. Local rules, private property boundaries and posted signs should be observed, and water temperature, depth and weather influence safety; summer swims are common, whereas winter swimming requires special precautions and equipment if attempted through holes in the ice. Visitors are advised to check current conditions and use common-sense safety measures such as not swimming alone and being mindful of sudden temperature changes.
