*** 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
Gravatnet is a freshwater lake in Agder County, Norway, with temperatures that follow the typical seasonal pattern for southern Norwegian inland waters. In winter the surface commonly approaches freezing, often around 0–4 °C (32–39 °F) where ice forms; spring warming is gradual, with waters typically in the 4–10 °C (39–50 °F) range. By summer the surface can rise to roughly 12–20 °C (54–68 °F) on warm days, though sheltered or deeper parts remain cooler. In autumn temperatures usually fall back into the 6–12 °C (43–54 °F) band as air temperatures drop and stratification breaks down. Local conditions such as depth, inflow from streams, recent weather and wind will cause variation from these general ranges.
Swimming in Gravatnet is generally allowed and common in summer months because Norwegian access rights (allemannsretten) permit entering and using most natural water bodies, unless specific restrictions are posted. Water quality in many Agder lakes is suitable for recreational use, but swimmers should exercise caution because cold water can cause shock even on warm days, and hidden depths, sudden drop-offs and boat traffic present hazards. It is sensible to check local signage or municipal information for any warnings, to swim with a companion, and to use appropriate safety gear.
