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.

The Vefsna River in Nordland County is a cold, glacial- and snowmelt‑fed watercourse whose temperatures vary substantially through the year and along its length. In winter the river is close to freezing, often around 0–4 °C (32–39 °F) in open stretches; during spring snowmelt temperatures typically rise to roughly 4–10 °C (39–50 °F) as runoff increases. In summer the warmest surface readings in slower, sheltered sections may reach about 10–18 °C (50–64 °F), though faster and more turbulent stretches remain cooler. By autumn temperatures decline again toward the 6–10 °C (43–50 °F) range as air temperatures fall and discharge patterns change. Local conditions, depth, flow and exposure to sun make spot-to-spot variation significant.
Swimming in the Vefsna is not broadly prohibited and is possible in calmer, shallow areas during the warmer months, but it carries clear cautions. Strong currents, cold temperatures outside mid-summer and sudden weather changes increase the risk of hypothermia and drowning, so many people use wetsuits or choose sheltered pools rather than main channels. Public access rights in Norway generally allow entering waterways, but swimmers should respect private land, heed local warnings and be mindful of conservation and safety measures, especially in important salmon habitats and near infrastructure.
