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
Norra Dellen, a lake in Kävleborg County known locally as Norra Dellen, has water temperatures that vary markedly over the year. In spring the surface waters are typically cool, roughly 2–10 °C (36–50 °F) as ice melts and the lake stratifies. Summer brings the warmest conditions, with surface temperatures often ranging from 15–22 °C (59–72 °F) on sunny, calm days; shallow bays can warm even more while deeper parts remain noticeably colder. During autumn the lake cools again, commonly falling to 6–12 °C (43–54 °F) as the surface loses heat, and in winter the lake is frequently ice-covered with water at or near 0 °C (32 °F) under the ice.
Swimming in Norra Dellen is generally possible and commonly practiced in summer because Sweden’s public right of access and local bathing spots allow recreational use of the shoreline. However, conditions vary: water quality should be checked locally, currents and sudden depth changes can pose hazards, and cold water in spring, autumn or near deep sections increases the risk of cold-water shock. Ice-cover in winter makes casual swimming unsafe unless undertaken as ice bathing with appropriate safety measures and local guidance. As always, swimmers should choose sheltered, designated areas and use caution appropriate to season and weather.
