Water Temperature: Daily Trends, Historical Records, and Forecast
❌ As of today, the minimum water temperature ranges less than 41°F (5°C). Such water is extremely cold and not recommended for swimming without proper preparation. In these conditions, the risk of hypothermia is very high, and prolonged exposure to the water can be hazardous to your health. If you decide to swim, it is important to have the appropriate gear, such as a wetsuit. Typically, only experienced swimmers or those who practice winter swimming venture into such waters. 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
Betarsjön, a modest lake in Västernorrland County, Sweden, follows the typical northern temperate pattern of seasonal heating and cooling. In spring (April–June) surface temperatures commonly rise from near freezing after ice-out to roughly 5–15 °C (41–59 °F) as daylight increases. Peak summer warmth (July–August) usually brings surface temperatures in the range of about 15–22 °C (59–72 °F), with shallow bays warming fastest on sunny days. During autumn (September–October) the water cools again to roughly 5–12 °C (41–54 °F) before the lake typically freezes over in late autumn or early winter, when temperatures hover at or just above 0–4 °C (32–39 °F) beneath ice cover. Local weather, depth and shading all influence these values, so actual measurements can vary year to year.
Swimming at Betarsjön is generally possible and commonly practiced in warm months, since many Swedish lakes are accessible for recreational bathing. There are no inherent restrictions tied to the lake itself, but access may be limited by private shoreline ownership or seasonal signage, and swimmers should always observe posted notices about water quality or safety. Cold-water risks, sudden depth changes and ice cover in winter make prudence essential: wear a buoyant aid if uncertain, avoid lone swims in cold conditions, and check local guidance for current conditions before entering the water.
