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
Suldalsvatnet, in Rogaland County, Norway, is a large, deep lake and reservoir whose surface temperatures are noticeably cool year-round. Typical seasonal surface ranges are roughly 2–8 °C (36–46 °F) in spring, 10–16 °C (50–61 °F) in summer — occasionally reaching about 18 °C (64 °F) in warm spells — 4–10 °C (39–50 °F) in autumn, and close to 0–4 °C (32–39 °F) in winter when ice or near‑freezing conditions can occur in sheltered bays. Because the lake is deep and connected to hydroelectric regulation, colder bottom layers persist even during warm months, and temperatures can vary with weather, depth and water inflow.
Swimming in Suldalsvatnet is generally permitted as it is a public body of water, and locals do swim in the summer where access is practical. However, swimmers should be cautious: the water is colder than many shallow recreational lakes, cold‑water shock is a real risk, and fluctuating water levels or currents related to reservoir operations and hydropower outlets can create hazardous conditions. Bathers are advised to choose sheltered, well‑known spots, avoid solitary swims, wear a wetsuit if unsure about cold tolerance, and obey local signage or restrictions around infrastructure.
