*** 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
Arstaddalsdammen in Nordland County, Norway is a man-made reservoir whose surface temperatures reflect the cool coastal and inland climate of the region. In winter the lake commonly sits around 0 °C (32 °F) and is often ice-covered; spring thaw typically yields surface temperatures of about 1–8 °C (34–46 °F) as the water slowly warms. In summer, on calm sunny days, surface readings can reach roughly 8–16 °C (46–61 °F), though deep water remains substantially colder. During autumn the temperature drops again into the 4–8 °C (39–46 °F) range as cooling and mixing resume.
Swimming in Arstaddalsdammen is physically possible, but not without caution. Because it is a regulated reservoir there are often steep banks, infrastructure, intake areas and the potential for rapid level changes, so some zones near the dam or equipment may be restricted for safety reasons. Even in summer the water is cold enough to cause cold-water shock or hypothermia, and deeper spots remain chilly. Anyone choosing to swim should obey local signage, avoid restricted areas around facilities, enter slowly, wear a flotation aid if uncertain, and be aware of the cold-water risks.
