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.

Luleälven, the Lule River in Norrbotten County, is a large, cold river system influenced by mountain snowmelt, Arctic latitude and hydroelectric regulation. Seasonal surface temperatures typically range from near freezing in late winter—around 0 °C (32 °F) when the river is ice-covered—to about 3–5 °C (37–41 °F) in spring during the thaw. In summer the main channel commonly reaches roughly 10–18 °C (50–64 °F), while shallow bays and slower side arms can warm to around 18–20 °C (64–68 °F) in warm years. During autumn temperatures generally fall back into the 5–10 °C (41–50 °F) band as cooling and increased flows resume. Releases from reservoirs and deep-water outlets can cause some stretches to be colder than nearby surface readings.
Swimming in Luleälven is generally permitted under Sweden’s access rights, and many locals and visitors enjoy bathing in sheltered inlets and downstream stretches in summer. However, swimmers must be cautious: cold water, strong currents, rapid level changes near dams and turbines, and remote conditions increase hypothermia and drowning risk. Areas immediately downstream of hydroelectric facilities are often unsafe or restricted, so local signage, knowledge of flow regimes and taking safety precautions are important when choosing where and when to enter the water.
