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
Östersund, situated on the shores of Storsjön in Jämtland County, experiences pronounced seasonal shifts in lake water temperature. In spring (April–May) the surface often ranges from around 0–8 °C (32–46 °F) as ice melts and the lake stratifies. Early summer in June typically warms to roughly 10–15 °C (50–59 °F), while midsummer in July and August can bring surface temperatures of about 16–22 °C (61–72 °F) in sheltered bays and shallower areas during warm years. By autumn the water cools again to roughly 8–14 °C (46–57 °F), and in winter the surface freezes in most years, with water at or below 0 °C (32 °F) under the ice.
Swimming in and around Östersund is generally allowed and practiced during the warmer months, with municipal beaches and private spots offering accessible entry points. The public right of access (Allemansrätten) and local facilities mean people can bathe freely, but conditions vary by weather, water depth and currents, so checking local water quality reports and observing safety measures is important. Cold-water risks apply both in shoulder seasons and for winter ice swimming, which is done by experienced bathers with precautions such as supervision, ice holes and thermal protection.
