*** 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
Oltedalsvatnet in Rogaland County, Norway, is a relatively cool, often clear lake whose surface temperatures vary noticeably through the year. In spring (April–May) the water typically sits around 2–8 °C (36–46 °F) as snowmelt and cold inflows dominate. During the summer months (June–August), surface temperatures can rise to roughly 12–20 °C (54–68 °F) on warm days, though shorter periods of warmth are common and deeper water remains colder. In autumn (September–October) temperatures usually fall back to about 6–12 °C (43–54 °F), and in winter the lake often approaches freezing, around 0–4 °C (32–39 °F), with ice cover possible in colder years. These figures are approximate and can change with weather, wind and water management.
Swimming is generally possible, and locals do bathe in the lake during the warmer months, but caution is advised. Oltedalsvatnet functions as a regulated reservoir, so water levels and currents can change with hydropower operations or water releases; these fluctuations, along with cold, deep water and hidden drop-offs, increase risk. For safety, swimmers should heed any local signage, avoid areas near intakes and dam structures, be prepared for cold-water shock, and consider short dips or a wetsuit for longer swims.
